Developing effective and gentle cosmetics for sensitive skin requires a meticulously curated selection of raw materials. The core philosophy shifts from mere functionality to one of maximum tolerability, focusing on ingredients that soothe, protect, and reinforce the skin barrier while minimizing potential triggers of irritation, redness, or stinging.

The foundation of these formulations is built on soothing and barrier-supporting actives. Key ingredients include:

• Ceramides: Essential lipids that repair and fortify the skin's natural barrier, reducing trans epidermal water loss and protecting against environmental aggressors.cosmetic raw materials

• Niacinamide (Vitamin B3): A multi-functional superstar that improves barrier function, reduces redness, and possesses anti-inflammatory properties.

• Panthenol (Provitamin B5): A potent humectant and anti-irritant that soothes and promotes skin healing.

• Oat Beta-Glucan and Colloidal Oatmeal: Renowned for their anti-inflammatory and itch-relieving properties, providing immediate comfort.

• Centella Asiatica (Cica) and Madecassoside: Powerful botanicals known to calm irritation and stimulate skin repair.

Equally critical is the strategic choice of base ingredients. Formulators prioritize high-purity, hypoallergenic emollients like squalane, caprylic/capric triglyceride, and diisopropyl dimer dilinoleate. Gentle, sulfate-free surfactants such as decyl glucoside and coco-glucoside are used for cleansers. Preservative systems also move away from parabens and formaldehyde-releasers towards milder options like phenoxyethanol (at low concentrations), ethylhexylglycerin, and organic acid-based systems (e.g., benzoic acid, sorbic acid).
