The role of moisturizing: to maintain the normal water content of the cuticle of the epidermis.
The stratum corneum of the skin is like a sponge. When the sponge is full of water, its softness and plasticity will increase. But once the sponge is dry, it will become hard and rough to the touch.
So if the skin is dehydrated:
(1) the skin will become rough, dry, tight, dark and dull.
(2) the skin keratinocytes can not metabolize normally, which can easily lead to the phenomenon of cutin thickening and desquamation.
(3) dry fine lines appeared around the eyes and cheeks.
(4) severe cases can cause dermatitis and cause itching, pain and burning discomfort.
Reminder:
The role of moisturizing is to replenish water, do not think that you are oily skin can not pay attention to moisturizing! If you don’t moisturize and maintain a good balance of water and oil, your skin will get worse and worse!
