They are the main element of solar protection and they have the function of reflecting, dispersing or absorbing the sun's rays, thereby protecting the skin from the harmful effects of the sun. Depending on how they act, they can generally be divided into two large groups:
With ZERO% sensitive skin or allergy-prone skin can take advantage of the benefits of the sun with a very high sun protection level against ultraviolet B radiation (FPS 50+); 0% chemical filters, 0% parabens and 0% perfumes, as well as being water resistant and protecting from ultraviolet A and infrared rays. It is the only mineral protector that contains Multi-CELL ANTIOX [ complex ], an anti free radicals complex that triggers the defence systems and repairs cells.
the most common ones are physical filters (they reflect radiation, dispersing it) and chemical filters (they absorb the energy from UV radiation). On the whole, solar filters are considered to be safe molecules. However, the use of some chemical filters such as oxybenzone or octocrylene is controversial, especially for young children and sensitive or reactive skin, as there is a greater probability of skin absorption and allergic reactions, which can also cause problems for people with stratum corneum integrity problems.
To minimise all these risks, it is advisable to use protection products with physical filters on sensitive skin. Inorganic filters, like zinc oxide and titanium dioxide, have the advantage of being very photostable and they do not cause allergic reactions. Lotions that contain inorganic filters are the best ones for avoiding sensitivity issues, irritation and photo allergy.
