EPIDERMIS
The outermost layer of human skin is composed of keratinocytes and contains melanocytes. Its main function is to store water. This layer has a 28-day skin metabolism cycle. However, with the influence of factors such as age and the external environment, the rate of keratin metabolism renewal slows down. The abnormal accumulation of old waste keratin will cause moisture loss and rough skin. When the skin is exposed to excessive sunlight, the melanin in the epidermis will also precipitate, become dull and cause spots.
DERMIS
It contains collagen and elastic fibers, which can provide support and elasticity for the skin, and secrete nutrients to supply the epidermis. However, when the productivity of fibroblasts decreases, the collagen decreases and the dermis becomes thinner, which will reduce the support of the skin, loss of elasticity and plumpness. If the aforementioned sun exposure penetrates deep into the dermis, it will also cause wrinkles on the skin.
SUBCUTANEOUS TISSUE

How to prevent rough skin?
The stratum corneum of the skin is like a sponge. When the sponge is full of water, it becomes soft. We must first do a good job of moisturizing, but also regularly remove dead skin cells from face.
