Sunscreen is the last step of skin care. In fact, strictly speaking, sunscreen does not belong to cosmetics, but belongs to the category of skin care products. Its main function is to protect the ultraviolet rays in the light and minimize the irritation and harm of ultraviolet rays to the skin. Therefore, the correct usage is to use it after basic moisturizing and skin care and before makeup, and the sunscreen effect will be better.
The sunscreen effect has nothing to do with the brand. The sunscreen effect is mainly related to the method, dosage and supplementary application of sunscreen value. The technique must be applied from the inside out, and the dose is almost the size of a coin. If it is outdoors, it is best to apply it every two hours.
