Lip Sleeping Mask Berry

A diester formed from malic acid and isostearyl alcohol. It conditions and smooths skin with no known safety issues in cosmetic use.

A synthetic emollient with properties similar to silicones, used for a smooth skin feel. Inert and not absorbed through intact skin, with no documented safety concerns in cosmetic formulations.

A synthetic polymer that functions as a lightweight occlusive emollient, providing slip and smoothness to formulations. It is an inert ingredient with no reported sensitization or irritation concerns and is widely used in cosmetic and personal care products.

A refined cellulose derivative processed from plant sources, used as a thickener and texturizing agent in cosmetics. It is an inert polysaccharide with no known sensitization or irritation potential and is widely used in personal care and pharmaceutical formulations.

A rich plant butter pressed from shea tree nuts, valued for softening and cushioning dry skin. It is generally well tolerated, though very rare allergic reactions have been reported and people with tree nut allergies who are cautious may want to patch test first.

A chemically produced wax derived from petroleum refining, used to add texture, viscosity, and occlusive properties to formulations. It is an inert ingredient with a long history of safe use in cosmetics and is well documented as non-toxic and non-irritating.

A plant-derived wax extracted from the Euphorbia cerifera shrub native to Mexico and the southwestern United States. It provides emollient and thickening benefits and has a long history of traditional use with no documented sensitization or irritation concerns at typical cosmetic concentrations.

A naturally occurring mineral silicate that adds shimmer and light-diffusing properties to cosmetics. Cosmetic-grade mica is well tolerated and should be free of asbestos and talc contamination.

A plant butter from the seeds of the Murumuru palm, used as an emollient in skincare formulations. Limited published cosmetic safety data exists, but it has not been associated with documented safety concerns, and the use pattern is consistent with other plant butters.

A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

A polyol ester emulsifier that stabilizes water-in-oil and oil-in-water emulsions with minimal irritation. Like other polyglyceryl esters, it is valued for its mildness and is used across a range of skincare and color cosmetics.

Dehydroacetic acid is a preservative regulated under the EU preservative annex with a set maximum concentration. Sensitization appears to be rare, though occasional contact dermatitis case reports exist, so people with reactive skin may want to patch test.

A plant-derived wax from carnauba palm leaves, widely used in cosmetics to provide texture and protective film-forming properties. Extensively documented as safe for topical use.

A stearic acid derivative used to thicken and stabilize formulations while providing mild emollient properties. Graded low concern with no documented sensitization or safety issues.

The base most products are built on. It carries the other ingredients and has no safety concern.

A corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

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

A fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.

A mineral salt used in cosmetics as a humectant and antioxidant. It is the same compound used in food and personal care products, and is well tolerated in both rinse-off and leave-on formulations.

A humectant that holds water at the skin surface for a more hydrated look. No safety concern.

A polysaccharide extracted from yeast cell walls or oat bran. Used for hydration and skin conditioning, beta-glucan is well tolerated with emerging evidence for supporting skin barrier function. No safety concerns flagged in cosmetic use.

A gentle, stable vitamin C derivative that the skin converts to active vitamin C, popular for brightening with less irritation than pure ascorbic acid. It is well tolerated and graded low concern in published assessments.
