Ultra Sport SPF 100 Sunscreen Lotion

A widely used organic UV-A filter in sunscreens. It can lose effectiveness in sunlight unless paired with photostabilizers, but safety reviews have not found it to pose a meaningful health hazard at approved use levels.

An organic UV-B filter that also stabilizes other sunscreen actives like avobenzone. The EU SCCS reviewed it and concluded it is safe at current use levels, though rare contact allergy has been reported and older, degraded product may form small amounts of benzophenone.

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 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.

An ester of palmitic acid and ethylhexanol, commonly used as an emollient and skin-conditioning agent. It is well studied and well tolerated in cosmetics.

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.

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 common preservative and fragrance/solvent ingredient found naturally in many essential oils. It is well tolerated by most people at the levels used in cosmetics, but it is one of the 26 EU-designated fragrance allergens and can trigger reactions in people with an existing sensitivity.

A natural wax secreted by honeybees, used as an emollient and texture builder in balms and salves. It is generally well tolerated. People with bee or pollen allergies should patch test, as rare sensitization has been documented.

A preservative that keeps products free of mold and bacteria. Reviewed repeatedly and considered safe at the low levels used.

A refined cellulose derivative processed from plant sources, used as a thickener and texturizing agent in cosmetics. It is an inert polysaccharide with no known sensitization or irritation potential and is widely used in personal care and pharmaceutical formulations.

A synthetic polymer used as a gentle exfoliant in scrubs and peeling products. It is an inert, non-biodegradable microparticle with no known skin irritation or sensitization potential when used topically in cosmetic formulations.

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 member of the paraben family used to prevent microbial growth in cosmetics. Like methylparaben, it has been reviewed extensively and found safe at the concentrations used in leave-on and rinse-off products.

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.

This is a stable, water-soluble derivative of vitamin C that converts to ascorbic acid in skin and is used for antioxidant and brightening support. It is generally better tolerated than plain ascorbic acid and has a low reported rate of irritation in formulation testing.

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

A plant-derived water or extract used mainly as a soothing humectant filler. Evidence for dramatic skin benefits beyond mild hydration and soothing is limited, but it is well tolerated by most people.
