Can wearing a mask in summer play a role in sun protection?

You can choose to wear a mask to prevent the sun. But it is best to choose a special sunscreen mask, because the general mask will make the skin unable to breathe, and the temperature is high in summer, and it is easy to grow acne or prickly heat.

The best choice for sun protection is to apply sunscreen and use parasols, and the effect will be better.

Excessive exposure of skin to ultraviolet rays will damage epidermal cells; Activate tyrosinase, accelerate pigment synthesis, destroy skin's moisturizing function, make skin dry, damage elastic fibers in dermis, produce fine lines, and even cause skin inflammation and burns under intense irradiation. When there is an abnormal situation, it will become pigmented skin cancer.

The main types of ultraviolet rays blocked or absorbed by sun protection are UVA (long-wave ultraviolet rays), UVB (medium-wave ultraviolet rays) and UVC (short-wave ultraviolet rays), and different ultraviolet rays do different harm to the skin.
