Indigo Overnight Repair

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

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

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

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

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 yeast ferment containing amino acids, vitamins, and polysaccharides used for hydration and skin conditioning. Published research indicates it is well tolerated and supports skin texture.

Green tea extract is a well-studied topical antioxidant with a long history of use in serums and moisturizers, generally well tolerated at cosmetic concentrations. Panel safety reviews of Camellia sinensis-derived ingredients have not identified meaningful topical hazard.

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

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 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 saturated fatty acid found in palm oil and naturally in the skin, used as an emollient to soften and condition skin. It is one of the most studied fatty acids and is well tolerated.

A fatty alcohol used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

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

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 widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.
