What are the precautions for choosing sunscreen
Look at the SPF value
When selecting a sunscreen, the first thing to look at is the SPF value of the sunscreen. The SPF value represents the sun protection factor of the sunscreen, that is, the protection ability of the sunscreen against ultraviolet UVB. Girls can use SPF value * Minimum erythema dose to get the ability of the sunscreen to protect against ultraviolet UVB.
Look at the PA value
When selecting a sunscreen, in addition to the SPF value, you also need to look at the PA value of the sunscreen. The PA value refers to the ability of the sunscreen to protect against ultraviolet UVA. Ultraviolet UVA can penetrate into the skin dermis, and it is cumulative and irreversible. If it is accumulated for a long time, it is easy to cause dermatitis, sunburn, tanning, etc.
Look at the water resistance
When choosing sunscreen, if it's in summer or going to the beach, girls also need to see the waterproof of the sunscreen. Girls can apply a little sunscreen on the back of their hands, and then pour water directly on the back of their hands to see whether the water on the back of their hands is in the shape of water beads or flakes. If it's in the shape of water beads, it means that the waterproof of the sunscreen is OK.
