Melascreen Anti-spots Radiance Serum

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

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 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.

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

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

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 mixture of fatty alcohols ranging from 14 to 22 carbons, used as emollients and emulsifiers in creams and formulations. The published evidence supports safety at cosmetic levels.

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.

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

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

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 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.

A strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.

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.
