Perfect UV Gel

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 mineral UV filter that sits on the skin surface and reflects and scatters UV light. It is one of the best-studied sunscreen actives and is generally considered non-irritating and safe for use, including on sensitive skin.

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 widely used UVB chemical filter with a long safety record at US-approved concentrations. Some lab and animal studies have raised questions about hormone activity and coral reef impact, which is why a few jurisdictions cap or restrict it, but human-relevant risk at labeled use levels is considered low by regulators.

A solvent and emollient ester used in leave-on and rinse-off formulas. The CIR Expert Panel reviewed alkyl benzoates and found no irritation even at full strength, with typical use levels ranging from 0.0008 to 50 percent depending on product type.

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

A broad-spectrum organic UV filter used widely in European and international sunscreens. Approved by the EU and other regulators as safe at cosmetic levels.

A modern UVA sunscreen filter widely used in Europe and Asia, valued for photostability and low skin penetration. It is not yet approved as a sunscreen active in the United States, which reflects a slower regulatory pathway rather than a specific safety finding against it.

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

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.

An organic UVB filter approved in the EU and widely used in Korean and Japanese sunscreens at up to 5 percent. It is highly photostable and shows low skin penetration in the reviewed data. It is not on the FDA-approved UV filter list, so US-formulated sunscreens do not use it; that is a regulatory-process gap rather than a documented safety finding against the ingredient.

A mineral thickener and anti-caking agent widely used in sunscreens and cosmetics to control texture and prevent ingredient separation. CIR has reviewed silica in cosmetic use and found no basis for concern at the levels used topically.

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 fermentation-derived polysaccharide used to thicken and hydrate formulas. It absorbs and holds water in the skin, contributing to a smooth texture. Limited clinical data but no known sensitizers or safety concerns at cosmetic use levels.

This branched hydrocarbon is one of the isoparaffins the CIR Expert Panel reviewed and found safe as used in cosmetics, including as an emollient in leave-on face creams. It is generally considered non-comedogenic and used mainly to give a lightweight, non-greasy skin feel.

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

A small-dose synthetic antioxidant that prevents oils and fragrance in a formula from oxidizing. Not shown to pose a toxicological risk at the levels used in cosmetics.

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.

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

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 widely used, gentle preservative also common in food. It is generally well tolerated, though it can occasionally cause mild, transient irritation in people with already-compromised or very reactive skin.

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