Radian-C Cream

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

A stable vitamin C derivative used to brighten and provide antioxidant support, more shelf-stable than pure ascorbic acid. It is generally well tolerated, though strong vitamin C forms can sting sensitive skin.

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

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 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 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 multi-ester emollient created from pentaerythritol and ethylhexanoic acid. It provides silky texture and skin conditioning with no documented safety concerns at cosmetic concentrations.

Derived from olive oil fatty acids, this PEG-free emulsifier is used at low concentrations to hold water and oil phases together in creams. Available safety and dermatological testing has not shown meaningful irritation or sensitization at use 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.

An olive-oil-derived emulsifier, almost always paired with cetearyl olivate, that holds water and oil together and leaves a light skin-like finish. It is well tolerated and graded low concern in published assessments.

A rheology modifier that thickens gels and serums while maintaining a lightweight, non-sticky feel. Provides suspension and stability in water-based formulas. Widely used and well tolerated.

A citrus-scented fragrance component. Fine for most, but it oxidizes over time into a known contact allergen, so it must be labelled in the EU.

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 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 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 floral fragrance component and one of the EU-labelled fragrance allergens. Usually fine, worth watching if you react to scented products.

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

A purified triterpene from Centella asiatica (the "cica" plant) used in soothing and barrier-support products, especially Korean formulas. It is well tolerated with a low reported irritation rate; the strong repair and anti-aging claims around it are more marketing than settled evidence.

A floral, rose-like fragrance compound found in many essential oils. It is one of the 26 EU-designated fragrance allergens, meaning a documented minority of people can develop contact sensitization, so brands must disclose it above set thresholds.
