Hydragenist The Rehydrating Radiance Cream-Gel

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

A citrate ester used as a solvent and plasticizer in cosmetics to dissolve active ingredients and adjust texture. It is well tolerated and widely used in formulations without documented safety concerns.

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

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.

Carbomer is a synthetic polymer used purely to thicken and stabilize gels and lotions, with negligible skin penetration due to its large molecular size. Safety reviews have found low toxicity and minimal irritation potential even in leave-on use.

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 synthetic gelling and stabilizing polymer that gives lotions and gels their smooth, cushiony texture. The large molecule stays on the skin surface rather than penetrating, and it is graded low concern in published assessments.

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.

The sodium salt of benzoic acid, used as a preservative in both foods and cosmetics. Decades of safety review support its use at typical cosmetic concentrations, with mild irritation the main reported issue in sensitive skin.

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

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.

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

A linoleic-acid-rich plant oil used as an emollient and, in some small pediatric studies, associated with support of the skin barrier when applied to infant skin. It is well tolerated with a low reported rate of contact reactions.
