What is the appropriate SPF?

In life, many women are afraid of sunburn. Not only will their skin become darker, but it will also become dull. In fact, all cosmetics sold on the market have a label, which is SPF, or sun protection index. So what is an appropriate sun protection index?

The sunscreen factors on the market currently range from 6 times to 40 times. The larger the multiple, the longer the sunscreen time and the better the sunscreen effect. However, products with high factors often contain large amounts of physical or chemical sunscreens, which are more irritating to the skin, easily clog pores, and even breed acne and blackheads.

There are two types of sunscreens: UV absorbers and UV shielding agents (such as ultrafine powders of titanium dioxide and zinc oxide). It is impossible to have an SPF of 20 or above without titanium dioxide. While absorbing ultraviolet rays, sunscreen has a certain irritating effect on the skin. If the ultraviolet absorber is excessive, it will become a burden on the skin. Therefore, the choice of sunscreen should be determined based on your workplace, time and sunlight intensity.

How to choose the right SPF value?

1. For people with normal skin type, the SPF value should be 8 to 12;

2. For people who are sensitive to light, an SPF value of 12-20 is appropriate;

3. People with sensitive skin should choose sunscreens with plant formulas or physical sunscreens containing titanium dioxide.

4. For office workers who are only exposed to the sun on their way to and from get off work, an SPF value of 15 or less is sufficient, with face sun protection as the main focus;

5. When playing outdoors or swimming at the beach, the SPF value of the sunscreen should be above 30. It is best to use waterproof sunscreen skin care products when swimming.
