UV Aqua Rich Watery Essence

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

A fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.

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.

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 palm/coconut-derived fatty ester used to soften skin and help dissolve oil-soluble UV filters. It sits fairly high on lab comedogenicity scales, so some acne-prone users report clogged pores, though this does not translate into a broader safety concern for general use.

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 synthetic emollient with properties similar to silicones, used for a smooth skin feel. Inert and not absorbed through intact skin, with no documented safety concerns in cosmetic formulations.

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 five-carbon sugar alcohol (polyol) that functions as an effective humectant comparable to glycerin, drawing moisture into the skin. It is well tolerated in cosmetics and assessed as safe by regulatory bodies at typical formulation levels.

A crosslinked acrylic polymer that thickens and stabilizes formulations. Published assessments show it to be well tolerated at cosmetic use levels, with no evidence of penetration into viable skin layers or systemic absorption.

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

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 common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

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 silicone with vinyl groups used in long-wear primers and foundations for enhanced adherence and smoothness. It is inert and well tolerated at cosmetic concentrations.

An emulsifier made from sorbitol and isostearic acid, used to stabilize oil-in-water formulas. The Cosmetic Ingredient Review panel assessed it as safe for cosmetic use at typical concentrations.

A synthetic polymer used as a film-former and thickener that creates a protective layer on skin. It has extensive use in cosmetics and pharmaceuticals with a well-established safety profile.

A basic amino acid naturally found in skin that draws moisture into the stratum corneum. It is well tolerated in cosmetics at typical concentrations and has been used safely in skincare formulations for decades.

Used like sodium hydroxide to adjust pH in cosmetics at very low levels. At finished-product pH, it is neutralized and well tolerated.

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.

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

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

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.

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.
