2, when applying sunscreen, do not ignore the neck, chin, ears and other parts, careful to cause uneven skin tone.
3, apply sunscreen once every three hours, because the efficacy of sunscreen is not lasting. If the sweat washes away the sunscreen, it should be painted again.
4, the amount of use should be sufficient, usually the amount of sunscreen applied to the skin is 2 mg per square centimeter, in order to achieve the desired sunscreen effect.
5, do not mix with other brands of sunscreen, mixed use will increase the possibility of skin allergies. The ingredients of various brands of sunscreen are inconsistent. If they are mixed and overlapped on the skin, they may cause the components to interfere or mutually repel each other, reduce the sunscreen effect, and even cause skin allergies.
