UV Perfect Milk

A lightweight, volatile silicone that gives serums and primers their silky slip and quick-evaporating finish. Human safety data are reassuring; the EU restriction on this ingredient in rinse-off products is about environmental persistence in waterways, not skin safety.

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.

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

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

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 mineral powder valued for its absorbent and soft-feel properties in cosmetics. Cosmetic-grade talc is required to be asbestos-free; inhalation risk from topical application is minimal. Generally well tolerated when used as intended.

A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.

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 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.

A silicone-based powder used to improve texture and slip in formulas. It is lightweight, absorbs excess moisture, and provides smooth application. Well studied in cosmetics with no skin safety concerns.

A naturally occurring fatty acid (also made in the body and found in many foods) used to thicken lotions and help stabilize cleansing bars. It is one of the most well-studied emollient ingredients and is not a meaningful irritant at cosmetic use 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 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.

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.
