A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A multi-ester emollient created from pentaerythritol and ethylhexanoic acid. It provides silky texture and skin conditioning with no documented safety concerns at cosmetic concentrations.

Lavender essential oil naturally contains linalool, geraniol, and coumarin, several of the recognized fragrance allergen constituents, so it can trigger contact reactions in fragrance-sensitive users even though it is a "natural" ingredient. It is not a general hazard for most people, but those with a known fragrance allergy should treat it like any other essential oil.

The sodium salt of lactic acid and a key component of the skin barrier and natural moisturizing factor that attracts water to the skin. It is well established as a safe and effective humectant with no known hazards at cosmetic concentrations.

A cyclic oligosaccharide derived from corn starch that acts as a solubilizer and delivery vehicle for other ingredients. It is chemically inert, well tolerated, and has extensive use in pharmaceuticals and cosmetics.

A phospholipid emulsifier from soy or sunflower that binds water and oil and helps other ingredients absorb. It is a natural component of skin membranes, well tolerated, and reviewed as safe as used; a soy-derived grade is not a meaningful concern for a soy food allergy because the protein is largely absent.

A class of naturally derived lipid compounds used to soften skin and support barrier health. They are extracted from plants or microorganisms and used at low concentrations as conditioning agents. Well tolerated with rare contact sensitivity.

A natural alkaloid and studied active ingredient in skincare, valued for its antioxidant properties and potential to promote local circulation and reduce puffiness. Topical application results in minimal systemic absorption, graded low concern in regulatory assessments.

A purified triterpene from Centella asiatica (the "cica" plant) used in soothing and barrier-support products, especially Korean formulas. It is well tolerated with a low reported irritation rate; the strong repair and anti-aging claims around it are more marketing than settled evidence.

A lab-made version of a lipid naturally found in the outer skin barrier. It is added to creams and cleansers to help replace lipids that washing can strip away, and it is not linked to irritation or safety concerns.

A polyphenol antioxidant from grapes and berries, used in skincare to defend against environmental stress. Published assessments indicate it is well tolerated; it may also support the skin barrier when used consistently.
