Formulation view Hydrating base with multiple glycol humectants, featuring Hydrolyzed Sodium Hyaluronate and Trehalose for deep hydration. Includes glycolipids and amino acid complexes for barrier repair, supported by Ginkgo and Apple stem extracts. Thickened with Carbomer and Xanthan Gum. Suitable for dry, dehydrated skin. Formulator's note: Multi-weight hyaluronic acid combined with biomimetic lipids aims for layered hydration and membrane repair, with stability dependent on pH adjustment.

Ingredients explained
- Water/Aqua/Eau
- Primary aqueous solvent and carrier; no specific incompatibilities, focus on microbial stability.
- Butylene Glycol
- Polyol humectant and solvent at 1–5%; aids solubilization, light feel
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Pentylene Glycol
- Polyol humectant at 1-3%; low irritancy, suitable for sensitive skin
- Diglycerin
- Diglycerin humectant and conditioner; low viscosity suitable for liquid formulas, very low irritancy.
- Diphenylsiloxy Phenyl Trimethicone
- Phenyl trimethicone for anti-foaming and slip; silicone-based, silky feel
- Squalane
- Emollient from plants or synthetic; light texture
- Hydrolyzed Sodium Hyaluronate
- Low-molecular-weight hyaluronic acid derivative with better penetration and strong hydration; different molecular weights provide hydration at various depths, typical concentration 0.1-1%.
- Trehalose
- Trehalose; mild humectant and stabilizer for proteins/actives; hygroscopic, light skin feel.
- Glycolipids
- Cell membrane lipids mimicking skin barrier structure; used in repair formulations and biomimetic membranes
- Cryptomeria Japonica Bud Extract
- Not decoded yet
- Alanine
- Amino acid for antistatic and conditioning; low irritation, slight salty taste at high levels
- Arginine
- Arginine for moisturizing/conditioning; amino acid, high biocompatibility, often used in blends.
- Glycine
- Humectant amino acid, 1–3%; small molecule, low irritation.
- Serine
- Humectant amino acid, 1–3%; high water solubility, compatible with sensitive skin.
- Threonine
- Threonine, essential amino acid for hair/skin; blended with other AAs for balance.
- Malus Domestica Fruit Cell Culture Extract
- Cell-culture apple extract for antioxidant skin conditioning
- Chamomilla Recutita Flower Extract
- Plant extract, soothing properties; contains natural allergens, high levels may irritate.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer
- Crosspolymer for thickening/film; needs neutralization to pH 7-8 to hydrate, check ion strength.
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Potassium Hydroxide
- Strong alkali pH adjuster, trace usage (<0.1%); corrosive, must be neutralized.
- Sorbitan Stearate
- Non-ionic emulsifier for O/W systems; hydrophobic, requires co-emulsifiers, inert at high purity
- Carbomer
- Gelling thickener requiring neutralization; watch out for ion compatibility
- Sodium Polyacrylate Starch
- Sodium polyacrylate starch graft, absorbent and binder; hydrophilic polymer for powders, watch for hardness changes upon hydration.
- Lecithin
- Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.
- Phenoxyethanol
- Broad-spectrum preservative at ≤1%; may irritate sensitive eye areas, often paired with ethylhexylglycerin
- Parfum/Fragrance
- Blended fragrance for odor; contains 26 restricted allergens, use caution in sensitive/child/eye products, verify compliance.
- Linalool
- Natural fragrance component at ≤0.05%; one of EU 26 allergens, caution for sensitive skin
- Benzyl Salicylate
- UV absorber/light stabilizer, restricted in EU; potential sensitizer, risk assessment needed.
- Blue 1
- Synthetic water-soluble dye for color; use within regulatory limits
