OUR PHILOSOPHY
Nature already solved sleep.
We just listened.
Why We Choose Natural Ingredients
The answer to sleeplessness was never a synthetic shortcut — it was the right ingredients, working with your body. Every ingredient in our formulas is there because science has validated what it does. No fillers, no label dressing. If it's in there, it's earning its place.
What "Melatonin-Free" Actually Means
Melatonin is a hormone your body already makes. Supplement it synthetically and your body notices — dialing back its own production, leaving you dependent and groggy. Our Sleep Patch skips the shortcut entirely. Instead, it delivers the cofactors — Magnesium, B6, B12, L-Theanine — your body needs to produce melatonin on its own, naturally and on schedule.
"The goal was never to knock you out.
It was to help your body remember how to rest."
SLEEP PATCH
The Sleep Patch
A transdermal blend of 6 natural actives crafted for deeper sleep, cellular recovery, and lasting calm — without a single milligram of melatonin.
0% MELATONIN
0% CALORIES
DRUG-FREE
NATURAL & PLANT-BASED
All ingredients sourced from nature · Validated by science · Delivered transdermally
Korean Pine Nut Oil
PINUS KORAIENSIS · SIBERIA & KOREA
Rich in pinolenic acid, a rare polyunsaturated fatty acid that supports appetite regulation and anti-inflammatory pathways. Applied transdermally, it nourishes skin while delivering calming lipid signals that prime the body for rest.
Tourmaline
BORON SILICATE MINERAL · NATURAL CRYSTAL
A naturally occurring mineral known to emit far-infrared radiation and negative ions. These properties are associated with improved microcirculation, reduced oxidative stress, and a gentle warming effect that may support muscle relaxation before sleep.
GABA
Γ-AMINOBUTYRIC ACID · NEUROTRANSMITTER
The brain's primary inhibitory neurotransmitter. GABA reduces neuronal excitability, quieting racing thoughts and anxiety that delay sleep onset. Transdermal delivery bypasses digestive breakdown, supporting direct bioavailability.
L-Theanine
CAMELLIA SINENSIS · GREEN TEA LEAF
Found naturally in green tea, L-Theanine promotes alpha brainwave activity — the same relaxed-yet-alert state achieved in meditation. Paired with GABA, it creates a synergistic calm that eases the body into sleep without sedation or grogginess.
Ecklonia Cava
BROWN ALGAE · DEEP PACIFIC OCEAN
A marine polyphenol harvested from deep-sea brown algae, clinically studied for its ability to improve sleep quality and duration. Its phlorotannin compounds are proposed to cross the blood-brain barrier, promoting deeper slow-wave sleep and supporting cellular longevity.
Magnesium Chloride
MGCL₂ · ANCIENT OCEAN DEPOSITS
The most bioavailable form of magnesium for transdermal absorption. Magnesium is essential for over 300 enzymatic processes, including melatonin synthesis, muscle relaxation, and nervous system regulation. Deficiency is one of the most common drivers of poor sleep.
Vitamins B6 & B12
Pyridoxine & Methylcobalamin · Essential Vitamins
B6 is a critical cofactor in the synthesis of serotonin and GABA — the neurotransmitters that govern mood and sleep. B12 supports the circadian rhythm and healthy nerve function. Together they ensure your body has the building blocks to produce its own sleep chemistry naturally.

The Science of the Blend
How It Works: Synergy Over Single Ingredients
Most sleep supplements pick one ingredient and dose it high. We took the opposite approach — a lower dose of multiple ingredients that activate each other. The result is a cascade your body recognizes, not a signal it has to override.
01
Calm the nervous system
GABA quiets neuronal activity while L-Theanine amplifies alpha brainwaves — together shifting the brain from alert to restfully calm without sedation. Tourmaline's far-infrared emission relaxes muscle tension at the same time, addressing the physical and mental simultaneously.
02
Unlock your body's own melatonin
Magnesium Chloride activates the enzymes needed for melatonin synthesis. Vitamins B6 and B12 supply the cofactors that convert tryptophan → serotonin → melatonin. Korean Pine Nut Oil reduces the inflammation that disrupts this pathway. Your body produces exactly what it needs — no surplus, no dependency.
03
Deepen and protect sleep quality
Ecklonia Cava's phlorotannins cross the blood-brain barrier to enhance slow-wave sleep — the deep restorative phase most supplements never reach. Meanwhile, Magnesium continues regulating cortisol, keeping you asleep rather than pulling you into light sleep cycles.
Single-Ingredient Melatonin
- Overrides your body's natural rhythm
- Builds tolerance over time
- Morning grogginess common
- Does nothing for sleep quality
vs
Checked Out Sleep Patch
- Works with your body's own chemistry
- Non-habit forming by design
- Wake up clear, not groggy
- Improves deep sleep architecture
Why No Melatonin?
Melatonin is a hormone — supplementing synthetically suppresses your own production over time, creating dependency and grogginess. Our patch gives your body the cofactors to make its own melatonin naturally, keeping your sleep architecture intact.
Frequently Asked Questions
Yes. Every ingredient in the Sleep Patch is naturally derived, non-synthetic, and non-habit forming. Unlike melatonin supplements — which can suppress your body's own hormone production over time — our formula works by supporting your body's existing sleep chemistry, not overriding it. It is designed for consistent nightly use.
As with any topical product, if you experience skin sensitivity, discontinue use and consult a healthcare provider.
The Sleep Patch is ideal for adults who struggle with falling asleep, staying asleep, or waking up feeling unrestored — without wanting to rely on pharmaceutical sleep aids or synthetic hormones. It suits those who travel frequently and deal with disrupted circadian rhythms, high-stress individuals whose racing mind delays sleep onset, and anyone who has found melatonin leaves them groggy in the morning.
It is also a strong choice for the wellness-conscious consumer who wants to understand and support their body's natural processes rather than bypass them.
Pregnant or breastfeeding individuals should consult their physician before use.
Those with known sensitivities to any listed ingredient — particularly magnesium compounds or pine-derived oils — should patch test before full application.
Individuals on prescription medications that affect the CNS or sleep-wake cycle should speak with their doctor, as GABA and L-Theanine may interact with these pathways.
The patch is not intended for use on children under 18 without medical guidance.
When you swallow a supplement, it passes through the digestive system before reaching the bloodstream — a process that degrades a significant portion of the active compounds, particularly GABA, which has limited oral bioavailability. Transdermal delivery bypasses digestion entirely, allowing ingredients to absorb directly through the skin at a steady, sustained rate throughout the night.
Mouth Tape
The Mouth Tape
The world's first hydrocolloid-based mouth tape that doubles as a peptide lip mask. Promotes nasal breathing for deeper sleep — while actively repairing your lips overnight.
Hydrocolloid Technology
Peptide-Infused
Latex-Free
Skin-Safe Adhesive
Hydrocolloid Matrix
Dermatology-Grade · Wound Healing Technology
Originally developed for advanced wound care, hydrocolloid creates a moist healing environment by absorbing moisture while maintaining a protective seal. On the lips, it draws out impurities, softens dry skin, and accelerates overnight repair — the same technology used in acne patches and medical dressings.
Peptide Complex
Bioactive Peptides · Signal Proteins
Short chains of amino acids that signal skin cells to produce collagen and elastin. Topically applied peptides support lip plumpness, reduce fine lines around the mouth, and strengthen the skin barrier — turning your sleep tape into an active overnight treatment.
Hyaluronic Acid
Sodium Hyaluronate · Naturally Occurring
A humectant capable of holding up to 1,000x its weight in water. In the hydrocolloid matrix, hyaluronic acid draws atmospheric moisture into the lip tissue, combating transepidermal water loss and ensuring you wake up with hydrated, supple lips instead of dry, cracked ones.
Vitamin E (Tocopherol)
Natural Antioxidant · Plant-Derived
A fat-soluble antioxidant that protects skin cells from oxidative damage caused by free radicals. In the mouth tape formula, it stabilizes the peptide complex while conditioning the delicate lip skin, reducing inflammation and promoting the natural healing process during sleep.
Skin-Safe CMC Adhesive
Dermatology-Grade · Latex-Free
A gentle, pressure-sensitive adhesive designed to hold securely through a full night's sleep without leaving residue or irritating sensitive skin. Formulated without latex, harsh solvents, or synthetic fragrances — safe for all skin types including those with sensitive skin or allergies.
Nasal Breathing Support
Functional Design · Sleep Science
Beyond ingredients, the tape's primary function is to encourage nasal breathing during sleep — the way the human body was designed to breathe. Nasal breathing filters air, humidifies it, produces nitric oxide, reduces snoring, and deepens sleep stages. No ingredient can replicate what breathing correctly does for your body.
The Science of the Blend
How It Works: One Tape, Two Jobs
Standard mouth tapes are passive — they hold your mouth shut and that's it. Ours is an active overnight system. The hydrocolloid matrix, peptides, and hyaluronic acid don't just coexist: each ingredient enables the next, turning sleep into a treatment window.
01
Seal and begin nasal breathing
The skin-safe adhesive creates a secure, comfortable seal that holds through a full night without residue. This single shift — mouth closed, nose open — triggers nitric oxide production, filters and humidifies incoming air, reduces snoring, and deepens sleep stages.
02
Activate the repair environment
The hydrocolloid matrix creates a moist microenvironment against the lips — the same mechanism used in advanced wound care. This draws out impurities, softens dry skin, and creates ideal conditions for the peptide complex and hyaluronic acid to penetrate and work.
03
Rebuild overnight
Hyaluronic acid floods lip tissue with moisture. Peptides signal collagen and elastin production. Vitamin E neutralizes oxidative damage and locks the repair in. By morning, lips are visibly softer, plumper, and healthier than when you went to bed.
Standard Mouth Tape
- Holds mouth shut. That's it.
- Often leaves residue or irritation
- No skin benefit
- Passive — inert while you sleep
vs
Checked Out Mouth Tape
- Promotes nasal breathing for deeper sleep
- Gentle, residue-free adhesive
- Active lip repair while you sleep
- Wakes up looking better than last night
Why Hydrocolloid Changes Everything
Most mouth tapes are just adhesive strips — functional but inert. Ours uses medical-grade hydrocolloid technology to make the tape an active overnight treatment. It's not just keeping your mouth closed — it's repairing your lips. Your sleep routine should be doing double duty.
Frequently Asked Questions
For healthy adults who can breathe freely through their nose, mouth taping during sleep is considered safe and is widely recommended by sleep specialists and ENT physicians. Our tape uses a gentle, skin-safe adhesive — it is not an airtight seal. If you instinctively open your mouth during sleep, the tape releases without resistance.
If you have significant nasal congestion, a deviated septum, or any condition that restricts nasal airflow, consult a physician before use.
The Mouth Tape is ideal for adults who snore, breathe through their mouth at night, wake up with a dry mouth or sore throat, or simply want to optimize their sleep quality through nasal breathing. It also works well for anyone wanting an active overnight lip treatment — the hydrocolloid and peptide formula makes it a genuine skincare product, not just a functional sleep tool.
Do not use if you have moderate to severe sleep apnea that has not been evaluated or treated.
Those with nasal congestion due to illness, allergies, or structural issues should not use the tape until nasal breathing is fully clear.
Individuals with sensitive skin or adhesive allergies should patch test on the inner wrist before lip application.
The tape is not recommended for children without direct parental supervision and medical advice.
Our adhesive is specifically formulated to be gentle on the delicate perioral skin. The hydrocolloid matrix actually conditions the skin as it works, and Vitamin E has anti-inflammatory properties that help protect against irritation. Most users report softer, healthier skin around the lips with continued use.
To remove, peel gently from the corners inward. If any redness occurs, discontinue use.
Bypassing digestion entirely · Steady 8-hour release · Direct absorption through skin
Why It Matters
Transdermal delivery.
Transdermal delivery.
The smarter way in.
When you swallow a supplement, it enters a gauntlet. Stomach acid, digestive enzymes, and first-pass metabolism in the liver all degrade active compounds before they ever reach your bloodstream. For ingredients like GABA — which has notoriously poor oral bioavailability — the majority of what you swallow is simply lost.
Transdermal delivery bypasses all of it. Our patch adheres to the skin and delivers a slow, controlled release of actives directly through the dermal layers into local tissue and systemic circulation — all night, at a steady rate, with no digestive interference.
The result is more consistent absorption, no spike-and-crash effect, and ingredients that work in sync with your sleep cycle rather than front-loading and fading by 2am.
8hr
Release
Sustained overnight delivery
Ingredients release steadily across a full 8-hour sleep window — not in a single surge that peaks and fades.
0×
GI Loss
No digestive degradation
Bypasses the stomach, liver, and first-pass metabolism entirely — none of the active compounds are broken down before absorption.

GABA
Meaningfully higher GABA bioavailability
GABA is poorly absorbed orally due to limited gut-to-blood transport. Transdermal delivery sidesteps this barrier entirely, potentially offering meaningfully better bioavailability than an equivalent oral dose -transdermal GABA research is ongoing.
✓
No Spike
No spike. No crash.
Pills and gummies flood the system at once — creating a spike that often fades mid-sleep. Our patch maintains steady plasma levels so you stay asleep, not just fall asleep.

Sleep is not a single state · It is an architecture · Eight hours of biology worth protecting
Why sleep is
more complex than you think.
Sleep isn't a single state — it's an architecture. Understanding what happens inside each stage explains why generic sleep aids so often fall short, and why supporting your body's natural chemistry matters more than any quick fix.
Stage 1 · N1
Light Sleep
The transition between wakefulness and sleep. Brain activity begins to slow, muscles relax, and you can be easily woken. This stage lasts only 1–5 minutes per cycle.
Entry PointStage 2 · N2
True Sleep
Body temperature drops, heart rate slows, and sleep spindles appear — bursts of brain activity that consolidate memory. You spend roughly 50% of your night here.
Memory ConsolidationStage 3 · N3
Deep Sleep
The most physically restorative stage. Growth hormone is released, cells repair, and the immune system strengthens. This is the stage Ecklonia Cava is clinically studied to enhance.
★ Most RestorativeREM Sleep
Dream Sleep
Brain activity surges close to waking levels. Emotional memory processing, creativity, and learning consolidation all happen here. REM cycles lengthen through the night.
Emotional ProcessingWhat disrupts your sleep architecture
Most people know they sleep poorly. Fewer understand why.
Synthetic Melatonin
Supplementing melatonin externally signals your brain to reduce its own production. Over time, your natural circadian output weakens — making you more dependent, not less.
Blue Light Exposure
Blue light from screens suppresses melatonin production for up to 3 hours after exposure by tricking your brain into thinking it's still daytime.
Cortisol & Stress
High evening cortisol directly antagonizes melatonin and blocks the transition into deep sleep. Racing thoughts at bedtime aren't just mental — they're biochemical.
Magnesium Deficiency
Up to 50% of adults are estimated to be magnesium deficient. Magnesium is essential for GABA activity, melatonin synthesis, and muscle relaxation.
Mouth Breathing
Breathing through your mouth during sleep reduces nitric oxide production and causes micro-arousals that fragment deep sleep — often without you ever fully waking up.
Circadian Misalignment
Irregular schedules, shift work, and jet lag push melatonin and cortisol out of sync — making it hard to fall asleep, stay asleep, or feel rested even after a full night.
Your body's 24-hour sleep-wake clock
Melatonin rises as it gets dark, peaks around 2–3am, then fades as cortisol climbs toward morning. Every ingredient in our Sleep Patch is timed to support — not override — this natural rhythm.

Why sleep quality affects everything
Sleep isn't passive recovery — it's active biology. What happens during those 7–9 hours shapes how you look, perform, feel, and age.
Sleep is your
best performance tool.
best performance tool.
Deep sleep (N3) is when human growth hormone (HGH) peaks — the body's primary signal for muscle repair, tissue rebuilding, and strength adaptation. Without sufficient deep sleep, the gains from your workout are only partially realized.
Reaction time, decision-making, and endurance all degrade measurably after even a single night of poor sleep. Studies of professional athletes show that extending sleep consistently improves sprint speed, accuracy, and mood simultaneously.
Magnesium in our Sleep Patch directly supports muscle relaxation and glycogen replenishment overnight. Ecklonia Cava's enhancement of N3 sleep means more time in the exact stage where physical recovery happens.This isn't passive rest — it's active rebuilding.
Sleep Patch → supports N3 deep sleep & muscle recovery- +9%Sprint speed improvement
Stanford study on basketball players who extended sleep to 10 hours per night showed significant gains in speed and shooting accuracy.
- 70%Of HGH released during deep sleep
Human growth hormone — essential for muscle repair and recovery — is predominantly released during N3 slow-wave sleep.
- 3×Higher injury risk when under-slept
Athletes sleeping fewer than 8 hours are significantly more likely to sustain injury, according to research published in Sleep journal.
- ↑Reaction time, focus & endurance
Even partial sleep restriction reduces cognitive performance equivalent to being legally drunk — directly impacting training quality.
Your skin repairs
while you sleep.
while you sleep.
The skin's circadian clock runs on its own 24-hour repair cycle — and the night shift is when the real work happens. Cell turnover accelerates, collagen synthesis peaks, and the skin barrier repairs itself from the day's environmental damage.
Poor sleep raises cortisol and inflammatory cytokines, degrading collagen and slowing the skin's natural renewal. The phrase "beauty sleep" is not a metaphor — it describes a measurable biological process that only occurs during sufficient, quality sleep.
- 11pm–2amPeak cell renewal window
Skin cell mitosis peaks between 11pm and 2am — making early, quality sleep critical for skin regeneration.
- ↑48%Increase in water loss when sleep-deprived
Poor sleep compromises the skin barrier, leading to dehydration, dullness, and increased sensitivity within 24–48 hours.
- 30%More collagen broken down under high cortisol
Elevated cortisol from poor sleep activates enzymes that degrade collagen and accelerate the appearance of fine lines.
- 2×More effective skincare absorption at night
Skin permeability increases at night — making topical treatments like our Mouth Tape's peptide complex significantly more effective overnight.
Sleep regulates
hunger, fat, and energy.
hunger, fat, and energy.
Two nights of short sleep is enough to dysregulate ghrelin and leptin — the hormones that control hunger and satiety. Ghrelin (hunger signal) rises. Leptin (fullness signal) falls. The result is a measurable increase in appetite — not from lack of willpower, but from biochemistry.
Sleep deprivation also impairs insulin sensitivity, making it harder for cells to uptake glucose efficiently. This is why chronic poor sleep is now considered an independent risk factor for type 2 diabetes.
- +24%Increase in hunger after 2 nights of short sleep
Research shows sleep restriction raises appetite hormones significantly in just 48 hours.
- 55%Higher obesity risk with chronic short sleep
Adults sleeping fewer than 7 hours per night are significantly more likely to develop obesity over time.
- ↓Insulin sensitivity after one week of poor sleep
Even one week of mild sleep restriction reduces insulin sensitivity in healthy adults.
- 300+Extra calories consumed daily when sleep-deprived
Studies show under-slept individuals consume significantly more calories the following day, driven by hormonal changes.
REM sleep is
emotional medicine.
emotional medicine.
REM sleep is when the brain processes the emotional weight of the day — consolidating difficult experiences, reducing their emotional charge, and building the resilience to face the next day.
Chronic REM disruption is now recognized as a primary driver of anxiety and depression, not merely a symptom. GABA and L-Theanine in our Sleep Patch directly support the neurological conditions for REM sleep.
- 40%Increase in anxiety after a sleepless night
UC Berkeley research shows a single night of no sleep triggers a 40% increase in anxiety levels.
- 2–3×Higher depression risk with chronic poor sleep
Insomnia is one of the strongest independent predictors of depression onset.
- REMThe emotional overnight therapy session
REM sleep strips the emotional charge from difficult memories while preserving the factual content.
- ↑Emotional regulation and stress resilience
People who consistently get high-quality sleep show measurably better emotional regulation and reduced reactivity to stress.
Deep sleep is
cellular housekeeping.
cellular housekeeping.
During deep sleep, the brain activates the glymphatic system — a waste-clearance network that flushes toxic proteins including beta-amyloid and tau, the plaques associated with Alzheimer's disease.
Deep sleep also triggers autophagy — the process by which cells identify and clear damaged components. Autophagy is one of the most researched mechanisms in longevity science, associated with reduced cancer risk and slower biological aging.
- GlymphaticSystem — only active during sleep
The brain's waste-clearance system is 10× more active during sleep than waking — removing the toxic proteins linked to neurodegeneration.
- ↑Autophagy peaks during deep sleep
Cellular cleanup — the mechanism most associated with biological aging — is significantly upregulated during N3 slow-wave sleep.
- 25%Higher all-cause mortality risk with chronic short sleep
Adults consistently sleeping under 6 hours show significantly elevated risk of cardiovascular disease and all-cause mortality.
- TelomereLength correlates with sleep quality
Telomere length — a key biomarker of biological age — is consistently shorter in chronic poor sleepers.
How Checked Out works with your biology
Most sleep products treat symptoms — they knock you out or flood your system with synthetic hormones. We take a different approach: giving your body the specific nutrients it needs to run its own sleep program correctly.
The result isn't sedation. It's alignment — your circadian rhythm working the way it was designed to, without interference or dependency.
- ✓ GABA + L-Theanine calm neurological activity at sleep onset — naturally
- ✓ Magnesium + B6 + B12 supply the cofactors for your own melatonin synthesis
- ✓ Ecklonia Cava deepens N3 slow-wave sleep — the stage most supplements skip
- ✓ Tourmaline addresses physical tension, so body and mind arrive at rest together
- ✓ Mouth Tape promotes nasal breathing, preventing micro-arousals that fragment deep sleep
- ✓ Transdermal delivery sustains all of this across a full 8-hour window
