Ingredients explained

Propolis Extract

Propolis extract for antimicrobial care; complex composition, potential allergy risk.

Aloe Barbadensis Leaf Water

Aloe juice, humectant and fragrance; perishable, requires preservatives, prone to browning.

Camellia Sinensis Leaf Water

Green tea leaf water containing polyphenols; offers soothing, astringent, and antioxidant effects, often a base for toners.

Butylene Glycol

Polyol humectant and solvent at 1–5%; aids solubilization, light feel

Cetyl Ethylhexanoate

Synthetic oil providing slip; large molecule, low penetration, non-comedogenic, suitable for dry or rough skin.

Glycerin

Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives

1,2-Hexanediol

Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives

Niacinamide

Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

High-molecular-weight thickener and emulsion stabilizer; requires electrolytes or acid adjustment near isoelectric point for optimal performance.

Cyclomethicone

Volatile silicone for light feel; contains D4 restricted by EU, must be <0.1% after 2026

Cetearyl Olivate

Natural emulsifier pairing with glucosides; skin-like feel, biodegradable, prone to oxidation requiring light protection

Betaine

Betaine for mild moisturizing/surfactant; low concentration 1-2% common, high may irritate.

Cetearyl Alcohol

Fatty alcohol emulsifier at 1-5%; non-ionic surfactant

Sorbitan Olivate

O/W emulsifier, HLB ~15, requires ionic co-surfactant, potential sensitizer.

Panthenol

Panthenol (vitamin B5) at 1–5%; moisturizing and reparative, supports barrier recovery

Ethylhexylglycerin

Mild conditioner and preservative booster at 0.5–1%; reduces preservative load, smooth feel

Allantoin

Skin soother at 0.5-2%; promotes cell regeneration

Xanthan Gum

Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration

Dimethicone/Vinyl Dimethicone Crosspolymer

Crosslinked silicone thickener at 0.5-2%; silky/matte feel, non-comedogenic, partial oil phase incompatibility, use co-solvent/pre-emulsification.

Sodium Hyaluronate

Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture

Arginine

Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.

Zinc Pca

Zinc salt for sebum control and antimicrobial; often paired with PCA sodium, high levels may cause sensitization

Betaine Salicylate

Salicylate derivative for keratolytic and antimicrobial action; milder than salicylic acid.

Mentha Haplocalix Extract

Mentha haplocalix extract, fragrance; provides cooling and scent, limit for children due to potential irritation.

Menthyl Lactate

Menthyl lactate, cooling and fragrance agent, provides mild menthol sensation for refreshing

Citric Acid

Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH

Melaleuca Alternifolia Leaf Oil

Tea tree oil, antibacterial and sebum regulating; highly sensitizing at concentrate level, dilute; avoid on broken skin.

Asiaticoside

Plant glycoside, healing and antioxidant; poor solubility, use low levels with solubilizers.

Asiatic Acid

Pro-healing active, 0.1–1%; stability affected by light, store protected from light.

Madecassic Acid

Madecassoside hydrolysis product for barrier repair and anti-inflammatory action; mild, low typical usage
