Ingredients explained
- Aqua
- Solvent, main base; microbial control is critical
- Hamamelis Virginiana Water
- Hamamelis water; tannins/flavonoids for astringent and soothing; low conc, generally well-tolerated
- Carthamus Tinctorius Seed Oil
- Natural seed oil rich in linoleic acid; moisturizing, prone to oxidation, needs antioxidants
- Glycerin
- Workhorse humectant at 3–10%; tacky at high levels, pair with occlusives
- Sodium Lactate
- Sodium lactate for moisturizing and exfoliation; pH buffering agent
- Sodium Acrylates Copolymer
- Water-soluble film former for styling and thickening; check residual acryloyl chloride for sensitive skin.
- Phospholipids
- Biomimetic repair and emollient, mimics skin lipids; typically processed at low temps, may be sticky at high levels
- Hydrogenated Polyisobutene
- Hydrogenated polyisobutene; petroleum-derived lubricant forming breathable film; high purity, low irritation/comedogenicity.
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- Cetyl Alcohol
- Cetyl alcohol for emulsification/thickening; high concentration >10% may irritate.
- Retinol
- Highly active and unstable, needs robust antioxidant encapsulation; 0.1-1.0%, pregnancy contraindicated
- Retinal
- Potent vitamin A aldehyde for cell turnover; low effective range 0.01-0.05%, unstable, avoid for pregnant users.
- Proline
- Proline, amino-acid humectant; boosts stratum corneum hydration, stable at pH 4-5.
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Helianthus Annuus Seed Oil
- Sunflower seed oil for emollient/occlusive; high linoleic acid, low comedogenicity.
- Tapioca Starch
- Tapioca starch; powder thickener/oil absorbent; inert, mild comed risk at high conc
- Leuconostoc/Radish Root Ferment Filtrate
- Bio-fermented filtrate for antimicrobial and anti-dandruff effects; assess individual variability, avoid in known allergy.
- Lonicera Caprifolium Flower Extract
- Honeysuckle extract for soothing and antioxidants; trace use, low allergenic risk
- Lonicera Japonica Flower Extract
- Honeysuckle extract for soothing; requires antimicrobial protection.
- Santalum Austrocaledonicum Wood Oil
- Not decoded yet
- Lavandula Hybrida Oil
- Essential oil for emollience and fragrance; contains allergens like linalool, requires EU 26 labeling
- Galactoarabinan
- Gum arabic polysaccharide; film-forming humectant; highly soluble.
- Glycosaminoglycans
- Water-soluble polysaccharide film former delivering intense hydration and emollience; used in moisturizing and anti-aging formulations.
- Potassium Hydrolyzed Polygamma-Glutamate
- Not decoded yet
- Tocopherol
- Natural antioxidant (vitamin E) at 0.1–1%; prone to oxidation, store protected from light
- Squalane
- Emollient from plants or synthetic; light texture
- Hydroxypropyl Starch Phosphate
- Thickener and bulking agent for creams; 1-5%, avoid cationic systems
- Dimethicone
- Silicone occlusive at 1–5%; provides smooth feel, non-penetrating, suitable for sensitive skin
- Polyglyceryl-10 Stearate
- Polyglyceryl-10 stearate emulsifier; multi-source, mild, co-emulsifier
- Lecithin
- Phospholipid emulsifier at 1-5%; biocompatible, moisturizing/antioxidant, prone to oxidation (add TBHQ), mild for sensitive skin.
- Xanthan Gum
- Natural thickener at 0.1–1%; provides gel texture, pH-stable, requires full hydration
- Tetrasodium EDTA
- Chelator removing metal ions to enhance antioxidant and preservative efficacy; very low usage, typically 0.05-0.1%, no direct skincare function.
- Citric Acid
- Buffer and chelator at 0.1–2%; adjusts pH, may irritate sensitive skin at low pH
- Alcohol
- Ethanol for solubility/drying at 5-15%; high conc. is drying/irritating, avoid lip/eye, low residue, balance with humectants.
- Potassium Sorbate
- Preservative effective below pH 6; combinable with sodium benzoate
