How to whiten tanned arms

In the hot summer, many women are worried that their fair skin will be tanned by the sun and lose its original luster and protein. So every time they go out, they feel that they must apply a layer of sunscreen, but it is troublesome and awkward, especially after sweating, the body will also emit a strange smell. So how to whiten the tanned arms? What methods can make our arms radiant!

How to protect yourself from the sun in summer

How can we keep our skin smooth and radiant in the hot summer? It should be said that the premise of beauty is sun protection. Because melanin determines the depth of skin color, and ultraviolet radiation will accelerate the rate at which melanocytes produce melanin, so in order to maintain healthy and fair skin, you must pay attention to sun protection.

It is not the case that the higher the SPF value, the better the effect

SPF stands for Sun Protection Factor, which refers to how long UVB protection lasts and how strong the protection is. SPF1 means the effective protection time is 20 minutes, and SPF5 means the effective protection time is 300 minutes. Generally speaking, when you are in places with a strong refractive index of sunlight, such as the seaside or grassland, or when you are exposed to the sun for a long time, you can choose sunscreen skin care products with SPF30-40. In general, SPF15-20 is enough, and do not exceed 30 at most.

Because the higher the SPF value of a sunscreen skin care product, the more UV absorbers it contains. Although the UV absorbers added to sunscreens sold on the market are produced in accordance with national standards and are harmless to the human body, this is not absolute because the degree to which human skin is stimulated varies from person to person. And the higher the SPF value, the more expensive it is.

In the above article, we learned how to whiten tanned arms. First of all, we must make sure that we choose the skin care products, and we should not wear shorts and short sleeves in our daily life. Prolonged exposure to high ultraviolet rays will cause the melanin to continue to rise and affect our fair skin.
