Can wearing a mask prevent tanning?

Wearing a mask has a certain sun protection effect, but it may also cause you to get tanned.

Ultraviolet rays are a general term, which are divided into long-wave, medium-wave and short-wave ultraviolet rays. Long-wave ultraviolet rays have very strong penetrability and can penetrate almost everything. They can reach the human body and cause sunburn. Medium-wave ultraviolet rays can reach the skin and tan the skin, but the possibility of sunburn is not high. Wearing a mask can only protect against medium-wave rays, but not long-wave ones. Under the sunlight, the places where you wear a mask are white, and the places where you don’t wear a mask are black. If there is no other sun protection, your face will be two colors and look ugly. In summer, you can wear a mask with good breathability to protect yourself from the sun, and at the same time, wear a sun hat or a parasol, and apply sunscreen. This way the sun protection effect will be better.

Can wearing a mask prevent formaldehyde?

It depends on the type of mask. If it is an ordinary mask, such as a gauze mask, it can only filter 30% of dust, let alone formaldehyde. Activated carbon masks have a certain anti-formaldehyde effect, and the gaps between activated carbon can absorb formaldehyde. If you want to have a good adsorption experience, you should not only pay attention to the adsorption aperture, but also pay attention to the thickness and number of layers of the mask. There are many kinds of activated carbon, both granular and powdered. Powdered activated carbon easily absorbs water and becomes saturated, so it needs to be exposed to the sun frequently. This is not to remove harmful substances, but to remove water vapor.

Masks do have a certain effect in preventing suntan and formaldehyde. The effect is related to the material of the mask. You should still check the function of the mask when buying it.
