Cellular rejuvenation
Science your cells actually recognize. Five products. Nine mechanisms. Zero pharmaceuticals.
The system
Each product targets a distinct biological mechanism. Nothing overlaps. Nothing is redundant.
Two audiences. One formula.
GHK-Cu is one of the most studied actives in both hair restoration and anti-aging skincare. Same formula — two completely different transformations.
For men
Rebuilding the hairline
GHK-Cu at 2% signals dormant follicles to reactivate, blocks DHT through four independent pathways, and suppresses PGD2 — the hidden second driver of hair loss that most brands have never heard of. Nine mechanisms targeting frontal thinning simultaneously.
For women
Hair loss, skin aging — or both
Women experience hair thinning too — hormonal changes, postpartum loss, and androgenic alopecia are all addressable with the same mechanisms. Apply to the scalp for hair regrowth, to the face and neck for collagen and anti-aging. Essoir I is one of the rare formulas that genuinely works for both.
Why it works
Every ingredient has published evidence. Every mechanism is distinct. Nothing in this system is decoration.
Phospholipid encapsulation delivers actives 7x deeper than standard serums — reaching the follicle bulb and dermis where the science actually happens.
Prostaglandin D2 is a hidden second driver of hair loss most brands don't target. Essoir I suppresses it with quercetin and ecklonia cava — ingredients with human cell evidence.
NAD+ and methylene blue restore cellular energy from two independent angles — precursor replenishment and direct electron transport enhancement.
Methylene blue photosensitizes the scalp for 650–850nm red light — amplifying photobiomodulation significantly beyond what either achieves alone.
Grass-fed tallow's sebum-mimicking fatty acid profile is one of nature's most effective carriers for actives deep into the hair follicle canal.
Catalase directly breaks down hydrogen peroxide — the root cause of hair bleaching from within. L-tyrosine then fuels new melanin production.
The routine
Every product has a clear role. Each step prepares or amplifies the next.
Bundles
Every product is stronger with the others. Save when you commit to the full system.
All products
Five products. Five steps. Complete cellular rejuvenation — for men targeting hair loss and women targeting skin aging.
The science
Every ingredient in every product has published evidence. Here is the full science behind each mechanism.
Phosphatidylcholine liposomes encapsulate actives in phospholipid bilayers that bypass the stratum corneum — delivering GHK-Cu, NAD+, and methylene blue directly to the dermis and follicle bulb rather than sitting on the surface.
University of Pennsylvania researchers found PGD2 is significantly elevated in bald scalp and directly inhibits hair growth. Quercetin inhibits PTGDS enzyme. Ecklonia cava polyphenols have outperformed minoxidil in human dermal papilla cell proliferation studies.
Essoir I targets 5-alpha reductase from four angles simultaneously: saw palmetto, rosemary extract (comparable to minoxidil in RCT at 6 months), pumpkin seed oil (44% reduction in hair fall, human RCT), and zinc PCA.
NAD+ declines with age, reducing mitochondrial function in follicle cells. Topical liposomal NAD+ with NMN precursor delivers directly to the scalp — bypassing the systemic absorption inefficiency of oral supplementation.
Applied before 650–850nm red light therapy, methylene blue acts as a photosensitizer creating a photodynamic amplification effect. Significantly enhances the photobiomodulation stimulus to follicle cells beyond what RLT alone achieves.
Hair greys through hydrogen peroxide accumulation bleaching the shaft from within. Catalase directly neutralizes H2O2. L-tyrosine provides the raw melanin precursor. Fo-Ti supports melanocyte function through traditional pathways.
Grass-fed tallow's oleic, palmitic, and stearic acids mirror human sebum ratios closely. The whipping process creates a lightweight aerated texture that absorbs without greasiness while maintaining exceptional follicle canal penetration.
Essoir Zero combines sulfur (antifungal + keratolytic), zinc oxide (antimicrobial + barrier repair), salicylic acid (follicle clearing), and mixed tocopherols (anti-inflammatory) to prep the scalp for maximum treatment absorption.

Our story
The science of cellular rejuvenation has existed for decades. GHK-Cu was discovered in 1973. NAD+ research has been in peer-reviewed literature since the 1980s. Methylene blue has been used clinically for over a century. The evidence was always there.
What was missing was a brand willing to actually use it — at therapeutic concentrations, in delivery systems that work, without hiding behind proprietary blends or burying actives in ingredient lists at ineffective doses.
Essoir was built to close that gap. Every product is formulated around the published evidence, not the marketing story. Every concentration is chosen for efficacy, not optics. Every mechanism is distinct — nothing in this system is filler.
The name comes from two French words — essor, meaning growth and upward momentum, and soin, meaning care and repair. That is what every product in this system does. Nothing more. Nothing less.
ESSOIR
Cellular rejuvenation
The philosophy
Every ingredient exists in the formula because published research says it should. No trendy actives, no label decoration. If the evidence isn't there, neither is the ingredient.
Most brands list GHK-Cu and call it done. We use 2% in a liposomal system. The difference between an effective dose and a marketing dose is the whole game.
Essoir I doesn't just contain GHK-Cu — it targets nine distinct biological pathways simultaneously. We design around mechanisms, then find the ingredients that hit them.
Grass-fed tallow has been used for skin health for centuries. Liposomal delivery was developed in the 1960s. Both belong in the same formula when the science supports it.
The science timeline
Methylene blue in clinical medicine
First used therapeutically. Decades of clinical data established its safety and mitochondrial mechanism before cosmetic applications were ever considered.
GHK-Cu discovered by Dr. Loren Pickart
Isolated from human plasma. Shown to decline significantly with age — high in your 20s, dramatically lower by your 60s. Fifty years of subsequent research confirmed its role in collagen synthesis, wound healing, and follicle signaling.
NAD+ research enters the scientific mainstream
The role of NAD+ in cellular energy, DNA repair, and mitochondrial function becomes one of the most studied areas in longevity biology. Its decline with age is now considered a central driver of cellular aging.
PGD2 identified as a driver of hair loss
University of Pennsylvania researchers discover prostaglandin D2 is significantly elevated in bald scalp and directly inhibits hair growth — a completely separate mechanism from DHT that most brands still haven't addressed.
Essoir — all of it, in one system
Five products. Every mechanism. Liposomal delivery. Therapeutic concentrations. No pharmaceuticals. The science was always there. Essoir puts it in your hands.
