Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Caffeine
- Active ingredient, 0.1–2%; promotes circulation, irritation risk at high concentration.
- Poria Cocos Extract
- Poria extract, traditionally used for hydration balance; data limited, usually a co-formulant
- Glyceryl Polyacrylate
- Water-soluble film former at 1–5%; light feel, soluble in polyols, non-occlusive
- Acetyl Tetrapeptide-5
- Acetyl tetrapeptide-5, a moisturizing peptide that enhances skin hydration via hydrolysis, typically mild, used to improve dryness
- Dipeptide-2
- Not decoded yet
- Acetyl Hexapeptide-8
- Acetyl hexapeptide-8; signal peptide, low concentration, used for firming and hydration, low irritancy.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Palmitoyl Tripeptide-1
- Palmitoyl Tripeptide-1 for repair; requires lipid carrier, unstable in aqueous phase
- Palmitoyl Tetrapeptide-7
- Palmitoyl Tetrapeptide-7 boosts collagen; use 0.1–1%, formulate with lipid carriers
- Caprylic/Capric Triglyceride
- Light occlusive and solvent at 1–10%; non-greasy feel, suitable for oily and combination skin
- Hydrogenated Lecithin
- Emulsifier from lecithin; stable, used in powder emulsions
- Palmitoyl Tripeptide-38
- Palmitoyl tripeptide; signaling peptide for collagen and antioxidants; 0.1-1% typical, light-sensitive
- Betaine
- Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.
- Polyporus Umbellatus Extract
- Not decoded yet
- Glutathione
- Antioxidant and brightening agent; unstable, requires antioxidants and protection from light.
- Ectoin
- Cosmectin and skin protector, enhances skin tolerance; water-soluble, 0.1–5% common, compatible with most systems
- Aminobutyric Acid
- GABA for hair hydration and shine, low irritation, acts as a conditioner.
- L-Ergothioneine
- Not decoded yet
- Ascorbic Acid
- Vitamin C, potent antioxidant requiring acidic environment for stability; oxidizes and discolors easily, needs light and air protection, concentration 1-10%, pure L-ascorbic acid is more irritating.
- Acetyl Glucosamine
- Glycosaminoglycan precursor supporting skin hydration and elasticity; highly biocompatible.
- Glucose
- Low-MW humectant and buffer; high hygroscopicity requires careful preservation and humidity control.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- 1,2-Octanediol
- Not decoded yet
- Tropolone
- Natural phenolic compound used as a skin conditioner; strong antioxidant activity, often a fragrance alternative.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
