Kalichem explains how explains how a SPF mineral booster based on biomimetic hydroxyapatite, used in sun care formulation, offers proven benefits in terms of multifunctionality, texture improvement, safety and low environmental impact
Sunscreens are well known to prevent damage related to environmental stress, including UV-A and UV-B rays.1,2 Chronic and prolonged exposure to sunlight causes damaging effects: UV-B are responsible for erythema and sunburn, while UV-A causes photo-ageing, acute and chronic photodermatosis and immunosuppression.
UV filters are molecules or molecular complexes that absorb, reflect, or disperse radiation and they represent the main protection measures against UV.3 They are divided into two main types: organic (chemical) and inorganic (physical) filters, due to their molecular nature and mechanism of action. Chemical filters absorb radiations while physical filters are mineral particles that reflect and diffuse them.4
