DIVE-IN Mild Suncream

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

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, 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 lightweight salicylate ester used mainly as a solvent to keep avobenzone stable and to give modern sunscreens a non-greasy finish. It has not drawn any published safety flags and functions cosmetically rather than as an active.

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 lightweight, silicone-like emollient derived from coconut/palm fatty alcohols, used to give lotions a smoother, less greasy feel. Listed in the EU CosIng database as a skin-conditioning agent with no restrictions.

A lightweight hydrocarbon that gives formulas a smooth, silky feel. Used in color cosmetics and sunscreens. Well tolerated and inert.

A light silicone emollient that spreads easily and gives a dry, non-greasy finish, common in Korean sunscreens and primers. It stays on the skin surface and is graded low concern in published assessments.

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

A lower molecular weight version of hyaluronic acid designed for better skin penetration. It has been extensively studied and shown to support skin hydration and barrier function with excellent tolerability in diverse formulations and skin types.

A broken-down form of hyaluronic acid with smaller molecules intended to penetrate more deeply into the skin. It functions as a humectant and is well tolerated, with the same safety profile as standard hyaluronic acid.

A chemically modified form of hyaluronic acid that improves stability and penetration in skincare formulations. Clinical assessments show it hydrates skin effectively and is well tolerated across sensitive and normal skin types.

A chemically cross-linked form of sodium hyaluronate designed to remain on the skin surface longer and provide sustained hydration. It functions as a humectant and is well tolerated, with the same safety profile as standard hyaluronic acid.

A quaternized derivative of hyaluronic acid that combines hydration and film-forming benefits for enhanced moisturizing effects. It is documented in cosmetic use as well tolerated, though people sensitive to quaternary ammonium compounds may want to perform a patch test.

A soothing humectant that helps skin and hair look conditioned. Very well tolerated.

A soothing, skin-conditioning compound (also found in comfrey root) commonly added to calm and hydrate irritated or sensitive skin. It has a long history of safe use with very low irritation potential.

A disaccharide sugar that acts as a humectant, drawing moisture into the skin and helping prevent dryness. It is well tolerated and commonly found in skincare formulas designed to support skin barrier health.

A lab-made version of a lipid naturally found in the outer skin barrier. It is added to creams and cleansers to help replace lipids that washing can strip away, and it is not linked to irritation or safety concerns.

A plant extract used for mild astringent and soothing effects. Evidence for its benefits comes mostly from traditional use and small studies rather than large trials, and the tannins it contains can be mildly irritating for some people, particularly in older distilled formulas that retain trace alcohol.

A plant extract used in Korean skincare for its soothing, antioxidant reputation. It is well tolerated with a low reported irritation rate; the soothing claims rest on limited but reasonable evidence.

A liquid wax extracted from jojoba seeds that closely mirrors skin sebum, widely used to soften and condition the skin barrier. It is generally well tolerated and suitable for most skin types.

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 plant-derived emollient and preservative formed from glycerin and caprylic acid (coconut) that helps retain moisture and supports formula stability through mild antimicrobial activity.

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.

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.

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

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 glycol used very widely in Korean and Western skincare as a lightweight humectant, solvent, and gentle preservative-booster, often in place of traditional preservatives. It has a low reported irritation rate at use levels and is graded low concern in published assessments.

An extract from red algae valued for its humectant and antioxidant properties. It is well tolerated and commonly used in marine-based skincare formulations.

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.
