Mineral Skin Nourishing Milk Sunscreen SPF 50

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

A silicone-based conditioning agent that adds smoothness and soft feel to formulas. Silicones in cosmetics are not absorbed by the skin and rinse cleanly, making them well-tolerated for most users.

A stearic acid derivative used to thicken and stabilize formulations while providing mild emollient properties. Graded low concern with no documented sensitization or safety issues.

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 rich, solid-at-room-temperature oil that deeply softens dry skin and hair. It is well tolerated overall, but its high lauric acid content is considered comedogenic by many dermatologists, so it can trigger breakouts in people who are acne-prone.

Ordinary salt, used in surfactant-based products like shampoos and body washes to adjust viscosity by interacting with the surfactant micelles. It has no meaningful toxicity concern at cosmetic use levels; the main practical downside is that too much can make a formula feel less mild.

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

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use 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.

An inert mineral oxide used as a filler and opacifying agent in color cosmetics. It is an FDA-approved colorant with a well-established safety record in cosmetic formulations.

Propylene carbonate is a small, high-boiling solvent used to dissolve other ingredients and thin out formulas in products like lipstick, eyeshadow, and mascara. Undiluted material caused moderate skin irritation in testing, but at the concentrations actually used in finished products (generally under 20%), CIR's panel found it at most moderately irritating and reaffirmed it safe as used, with no meaningful sensitization or photoirritation seen.

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 silane used to improve texture and conditioning properties in leave-on cosmetics. It is hydrolyzed during formulation and creates silicone-like benefits; well tolerated at standard use levels.

A naturally occurring mineral silicate that adds shimmer and light-diffusing properties to cosmetics. Cosmetic-grade mica is well tolerated and should be free of asbestos and talc contamination.

A rich plant butter from mango seed kernels, valued for its emollient and protective properties. It is generally well tolerated, though very rare allergic reactions have been reported; those with tree nut allergies may want to patch test first.

A mild enzymatic extract from papaya fruit that softens and hydrates skin. It is generally considered safe, though those with tree fruit allergies may wish to patch test first.

Mineral pigments used to add color to cosmetics. Iron oxides are FDA-approved colorants with a well-established safety record in cosmetic formulations.
