Formulation view Solvated in Propylene Glycol and Water, featuring a multi-actives stack including Niacinamide, Azelaic Acid, Salicylic Acid, and Retinol.

- Polyol humectant at 3-10%; hygroscopic, slight tackiness, mild irritation at high conc., verify preservative efficacy, no allergen.
- Purified Water
- Deionized or purified water serving as the formulation solvent base; requires protection from microbial contamination, typically constitutes the majority of the formula.
- Niacinamide
- Niacinamide at 2–5%; improves texture, controls oil, brightens; high levels may cause sensitivity
- Azelaic Acid
- Acne and pigment agent; 15-20% can be irritating, needs controlled release or lower doses.
- Polysorbate 20
- Non-ionic emulsifier and cleansing surfactant; contains PEG, control microbial load.
- 1,2-Hexanediol
- Polyol solvent and preservative booster at 1–5%; light feel, can replace some traditional preservatives
- Sodium Hyaluronate
- Potent humectant at 0.1–2%; different MW for penetration depth, high levels may draw moisture
- Salicylic Acid
- Lipophilic BHA at 0.5-2%; exfoliant/sebum control, irritation/sensitization at high conc., photosensitivity (SPF needed), avoid sensitive/pregnant.
- Hinokitiol
- Natural antistatic and hair conditioner; low irritancy, comedogenicity data not publicly available
- Melaleuca Alternifolia Leaf Oil
- Tea tree oil, antibacterial and sebum regulating; highly sensitizing at concentrate level, dilute; avoid on broken skin.
- Retinol
- Highly active and unstable, needs robust antioxidant encapsulation; 0.1-1.0%, pregnancy contraindicated
