Precautions for masks
Although the mask has a good effect, it can't be used every day. Especially a cleaning mask. For example, applying a mask to the skin is equivalent to eating big fish and big meat. If you eat big fish and meat every day, people will get fat. There will be various health problems after obesity, and so will the skin, so moderation is the most important.
If the cuticle of the skin is thick, after applying the mask, the effect of the mask will be greatly reduced because the cuticle is too thick, which hinders the close contact between nutrients and the skin, so it is very necessary to exfoliate once a week.
