Tanu Recovery Serum

A serum formulated to visibly support stressed-looking skin, replenish hydration, support a comfortable-feeling barrier, and improve the appearance of post-treatment-looking redness and sensitivity.

Tanu is a concentrated serum designed to support skin when it looks depleted, reactive, or in need of comfort. Copper tripeptides are housed within a liposomal carrier system. Skin-identical ceramides, acetyl tetrapeptide-40, glycerin, propanediol, dimethyl isosorbide, and soy lecithin pair to deliver lightweight hydration and a silky serum feel.

What makes it unique

• Designed for skin that looks stressed, compromised, or recovery-prone
• Supports the look of calmer, more resilient skin after visible irritation
• Pairs research-anchored peptides and skin-identical ceramides with lightweight humectant hydration
• Helps improve the appearance of redness-prone, fragile-looking, or uneven skin

Best for

• Post-procedure-looking skin (on unbroken skin)
• The appearance of visible redness
• Reactive-looking skin
• Compromised-looking barrier
• Dry or tight-feeling skin
• Dull, depleted-looking skin
• Uneven-looking tone
• Fragile or sensitive-feeling skin
• Rough or uneven texture

Key ingredients

• Copper Tripeptide-1
• Ceramide Complex
• Acetyl Tetrapeptide-40

Size: 40 ml

Tanu came from a frustration I had with the ‘recovery’ category. Most products in it are silicone-thickened creams designed to feel soothing — without any meaningfully researched active inside them. In regenerative medicine, the principle is to work with the body’s own biology, not against it. GHK-Cu is a peptide your plasma makes naturally — and one researchers have studied for decades. Tanu is the recovery layer I wanted on my own shelf.

Tanu is built on a principle drawn from the regenerative biology literature: that skin responds best to ingredients which work alongside its natural processes. The active architecture pairs Copper Tripeptide-1, housed within a biomimetic phospholipid carrier, with a peptide researched in connection with visibly reactive skin and a complex of ceramides identical to those found in healthy skin.

Copper Tripeptide-1 (GHK-Cu), liposomally encapsulated — a naturally-occurring human tripeptide-copper complex. GHK is a peptide first isolated from human plasma by Loren Pickart in 1973. Research has documented that plasma GHK concentrations decline measurably with age — from approximately 200 ng/mL in the third decade of life to ~80 ng/mL by the sixth. The peptide has been extensively studied across the dermatology and regenerative-biology literature, including research on its role in fibroblast biology (Pickart & Margolina, Cosmetics, 2018) and broader gene-expression research spanning tissue-remodeling, antioxidant-defense, and DNA-repair pathways (Pickart et al., Int J Mol Sci, 2018).

Raw GHK-Cu is hydrophilic and structurally large. In Tanu, GHK-Cu is housed within soy lecithin phospholipid bilayers — a carrier structure that mirrors the architecture of natural cell membranes. Liposomal encapsulation has been extensively studied in the cosmetic formulation literature as a means of stabilizing peptides in topical formulations (El Maghraby et al., Arch Dermatol Res, 2012), with research on peptide carrier systems dating back several decades (Vora et al., J Pharm Sci, 1995).

Acetyl Tetrapeptide-40 — a peptide studied in connection with visibly reactive skin. Researched in the context of VEGF biology and the appearance of reactive, visibly red-looking skin — an area of active investigation in cosmetic science. Added at cool-down only, after the batch is verified below 35°C.

Ceramide Complex — lipids identical to those naturally found in healthy skin. A multi-ceramide blend of Ceramide NP, AP, and EOP with cholesterol and phytosphingosine. Ceramides comprise approximately half of the stratum corneum’s intercellular lipid lamellae and have been documented to decline measurably with age, sun exposure, and barrier-disruptive events. Topical ceramide research is an established area within dermatology and cosmetic science.

Disodium EDTA — non-negotiable in a copper-peptide formula. Trace metals catalyze the degradation of GHK-Cu. Disodium EDTA is dissolved in the water phase before the peptide is ever introduced. It is the first thing into the vessel and the reason the peptide is still intact at the end.

GHK-Cu is the most-studied member of the copper-peptide family. Acetyl Tetrapeptide-40 is researched in connection with capillary-related visible redness. Ceramides are the structural lipids of healthy skin. Liposomal carriers are a well-established cosmetic technology. Recovery, formulated as a system.

Patch test first. Apply a thin layer to clean skin and follow with moisturizer if needed. Avoid use on broken or actively irritated skin. Consistent use over 4–6 weeks as tolerated is recommended for best results. If using after lasers, peels, microneedling, injectables, surgery, or another professional treatment, consult your licensed provider first.
