Girls who wear makeup in summer will wear very thin makeup to make their skin "breathe". Does the skin really breathe?

It depends on how to understand the meaning of breathing. According to the problem, the skin can breathe. As an organ, skin is responsible for the metabolism of our body.

In fact, more accurately, the skin only "breathes", not "sucks". Pores and sweat glands can excrete excess water and carbon dioxide in the body, but they cannot inhale oxygen (less than 1% oxygen can pass through the skin). You can do a simple experiment to know whether your skin can breathe. Wrapping your body with plastic wrap will make you feel bored, uncomfortable and a little breathless after a while. For skin care cosmetics, the "breathing" of the skin mentioned here should not actually refer to the inhalation of oxygen, but should refer to the permeability of the skin epidermis.

The permeability of skin epidermis includes: substances can penetrate the epidermis (which will make the epidermis moist but not dry); The stomata on epidermis, sweat glands and sebaceous glands are open. In summer, if girls wear heavy makeup, it will affect the smoothness of pores, sweat glands and sebaceous glands of the epidermis, thus hindering the "breathing" of the skin. The good permeability of epidermis maintains the normal metabolism of skin and makes skin smooth and delicate. Therefore, summer makeup should be as thin as possible, so as not to affect the "breathing" of the skin surface. This is the reason why girls who wear makeup in summer are very thin.

Finally, popular science: ordinary cosmetic ingredients will not enter subcutaneous tissue through epidermis and dermis. The substance that can really enter subcutaneous tissue only exists in medicine and research. Lung breathing actually affects our skin. People with poor breathing in the lungs usually look a little yellow.
