Cryo Rubber Mask With Moisturizing Hyaluronic Acid

A light, low-odor glycol used as a solvent and humectant, extremely common in Korean toners and essences. It has a low reported irritation rate and is graded low concern in published assessments.

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

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 form of vitamin B3 used to support a more even-looking tone and a comfortable barrier. Well tolerated at cosmetic levels.

A glycol used very widely in Korean and Western skincare as a lightweight humectant, solvent, and gentle preservative-booster, often in place of traditional preservatives. It has a low reported irritation rate at use levels and is graded low concern in published assessments.

A lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

A common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

A PEG-based emulsifier that blends oils and water in formulas. It is a workhorse ingredient in stable emulsions and is approved for cosmetic use. Well tolerated.

A water-soluble humectant that holds moisture and gives essences a soft feel. It is well tolerated and graded low concern in published assessments.

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

A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.

A disaccharide sugar that acts as a humectant, drawing moisture into the skin and helping prevent dryness. It is well tolerated and commonly found in skincare formulas designed to support skin barrier health.

A lightweight carrier oil expressed from macadamia nuts, rich in oleic acid and similar in composition to skin lipids. Very well tolerated in cosmetic use, though individuals with tree nut allergies who are cautious may want to patch test.

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

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

A humectant naturally derived from sugar beets that helps skin draw in and hold water; it has a long history of safe use with no meaningful irritation or sensitization concerns.

A soothing, skin-conditioning compound (also found in comfrey root) commonly added to calm and hydrate irritated or sensitive skin. It has a long history of safe use with very low irritation potential.

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

A liquid wax extracted from jojoba seeds that closely mirrors skin sebum, widely used to soften and condition the skin barrier. It is generally well tolerated and suitable for most skin types.

An extract from red algae valued for its humectant and antioxidant properties. It is well tolerated and commonly used in marine-based skincare formulations.

A small glycol used as a solvent and to boost the absorption of actives, and to help preservatives work at lower levels. It is well tolerated and graded low concern in published assessments.

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

A preservative and antioxidant that helps prevent microbial growth and oxidative degradation in formulas. Published assessments support its use at cosmetic levels.

A disaccharide (table sugar) that acts as a humectant to improve skin hydration and is a naturally occurring component of the skin barrier. It is well established as safe for topical cosmetic use with no known hazards.

A soothing humectant that helps skin and hair look conditioned. Very well tolerated.

A mild plant-derived emulsifier combining polyglycerol and lauric acid. Used in gentle formulas to blend oil and water phases; well tolerated across skin types at cosmetic concentrations.

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.

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

A salt form of glycyrrhizic acid, a compound from licorice root prized for soothing irritated skin. It is well tolerated at cosmetic levels and has a long history of use in skincare formulations.

A salt derived from citric acid that buffers pH and prevents metal oxidation in formulas. Widely used in food and cosmetics, it is well tolerated at cosmetic concentrations.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A five-carbon sugar alcohol (polyol) that functions as an effective humectant comparable to glycerin, drawing moisture into the skin. It is well tolerated in cosmetics and assessed as safe by regulatory bodies at typical formulation levels.

A simple sugar that functions as a humectant to bind moisture into the stratum corneum and is a component of the natural moisturizing factor. It is well tolerated in cosmetics and has no known sensitization concerns.

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.
