When the skin is regularly treated with whitening agents, it must be protected against UV rays in order to avoid the stimulation of pigmentation processes that the previous treatments are designed to contrast. Sunscreens with a high protection factor (SPF 50+) must therefore be used for:
- prevent the production of melanin, which is activated by UV radiation
- protect the skin against photo-induced free radicals
In fact, after exfoliation process, skin becomes more susceptible to attacks by free radicals (reactive oxygen and nitrogen species), which can trigger the oxidative processes that causes cell damage and skin ageing.
PHOTOWHITE uses the combination of various sunscreens to ensure broad spectrum protection against UVA and UVB rays.
- optimal dispersion within the formulations and therefore homogeneous and safer protection
- molecular stability after irradiation, which keeps the initial and declared SPF value constant over time
- absence of the white effect on the skin upon application (typical of physical filters), pleasant texture and excellent spreadability
