How does Maxrosa sunscreen work? According to the European Union regulations for cosmetic products, there are several rules that a sunscreen must comply with. For effective and safe protection, the UVA filter in the formula must be at least 1/3 of the SPF. The minimum critical wavelength is 370 nm (nanometers). Our sunscreen formula is designed in accordance with these rules. There are several different and special sunscreen filters in Maxrosa Sunscreen. Depending on their structure, these filters act both by absorbing UV rays and changing their structure, and by reflecting the rays and eliminating them. It is effective against both UVA and UVB rays. Maxrosa sunscreen belongs to the category of creams with SPF 50+, i.e. a high protection index. It prevents damage and irritation caused by solar radiation. It provides protection for sun-sensitive skin. It does not make the skin greasy and does not leave a sticky feeling.
