In this section we answer frequently asked questions about Biotherm Waterlover Hydrating Sun Milk SPF30 400ml
Sunscreen gets its protective power from ingredients called sun filters, which fall into two groups. "Mineral" is the common name for inorganic filters, of which there are only two: zinc oxide and titanium dioxide. "Chemical" is the common name for organic filters, which are carbon-based compounds and cover multiple different ingredients. A mineral sunscreen uses only inorganic filters, a chemical sunscreen uses only organic filters, and a sunscreen that combines both is known as a hybrid.
Both types of filters mainly protect the skin by absorbing UV radiation. Mineral filters, along with a few organic ones, also reflect a small portion of it.
SPF measures protection against UVB radiation. In the EU, the highest SPF on a cosmetic sunscreen label is SPF50+, which corresponds to the "very high protection" category and is used when the measured SPF is 60 or higher.
Some sunscreens, usually designed for specific skin conditions, are classified as medical devices rather than cosmetics, and these can show higher values, such as SPF100.
