Solkrem

Solkrem is a cosmetic product designed to protect the skin from ultraviolet (UV) radiation from the sun. It is used to prevent sunburn, reduce photoaging, and lower the long-term risk of skin cancer. Solkrem products are typically labeled with an SPF value and often described as broad-spectrum when they protect against both UVB and UVA rays.

There are two main categories of solkrem formulations. Chemical (organic) filters absorb UV energy, while mineral (inorganic) filters such as zinc oxide or titanium dioxide reflect or scatter UV light. The choice of filters affects texture, appearance, and photostability, with some people preferring mineral sunscreens for sensitive skin or mineral-based formulations for their perceived environmental profile.

Application and usage guidelines emphasize applying a generous layer to all exposed skin about 15 to 30 minutes before sun exposure. Reapplication is recommended every two hours, or more frequently after swimming, sweating, or towel drying. Water-resistant formulations offer longer protection in water or during activities, but reapplication is still necessary after water exposure. Sunscreen is most effective when used in combination with protective clothing, hats, and shade.

Safety and regulation vary by region. Some ingredients have raised safety or environmental concerns and may be restricted or reformulated in certain markets. For infants under six months, sun avoidance and protective measures are advised, and healthcare guidance should be sought. Consumers are advised to read labels for SPF, broad-spectrum protection, and any regional warnings or reef-safety notes.
