Retro Matte Lipstick - Ruby Woo

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

A mild white clay that absorbs excess oil and lightly buffs the skin surface in wash-off masks; it is well tolerated across skin types and rinses away cleanly.

A refined mineral wax used to firm up ointment and balm texture and help form an occlusive barrier alongside petrolatum. Highly refined cosmetic-grade mineral waxes have long been reviewed as inert at the concentrations used in personal care products.

A highly refined, inert petroleum-derived emollient that has been used in cosmetics and skincare for over a century. It creates a protective moisture barrier on the skin and is well tolerated by the vast majority of users, with minimal risk of irritation or sensitization.

This branched ester is a CIR-reviewed emollient used to give creams and lotions a silky, fast-absorbing after-feel. It is generally rated non-comedogenic and has not shown irritation or sensitization concerns in the available safety data.

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 mineral thickener and anti-caking agent widely used in sunscreens and cosmetics to control texture and prevent ingredient separation. CIR has reviewed silica in cosmetic use and found no basis for concern at the levels used topically.

A lightweight, odorless emollient made by combining coconut or palm-derived fatty acids with glycerin. It spreads easily, feels non-greasy, and has a long history of use in skin and hair products with no meaningful irritation or sensitization signal.

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 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 or extracted aromatic aldehyde that mimics vanilla scent. It is a known contact allergen in people with fragrance sensitivities, and oxidation over time can increase allergenicity, making it a watch-if-sensitive ingredient in cosmetics.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

A plant-derived emollient and emulsifier made from glycerin and oleic acid, typically from olives or canola. Softens skin while stabilizing oil-water formulas; well tolerated at typical use levels.

VP/Hexadecene Copolymer combines a petroleum derived hydrocarbon with vinylpyrrolidone to form a thin, glossy film that helps waterproof mascara, foundation, and long wear makeup grip skin and lashes. CIR reviewed it with the broader vinylpyrrolidone polymer group, and patch testing on a product with nearly 15% of the ingredient produced no skin reactions in 50 subjects, with no eye irritation reported in a separate eye shadow test.

A silane used to improve texture and conditioning properties in leave-on cosmetics. It is hydrolyzed during formulation and creates silicone-like benefits; well tolerated at standard use levels.
