The function of moisturization

The human body consists of 70% of water hence it gives vitality to skin. Skin gives us the indication of the level of water. If the amount of water decreases, the layer of skin loses its elasticity and becomes dry. We often say that the skin is dry; it means that the moisture is low.

When the water level is balanced or the skin is well moisturized, the skin becomes flexible and free of wrinkles. With good moisture, the skin cells regenerate and they renew the skin. Therefore, we should drink more water.


Nutrition function of skin

Lipids are the essential parts of the good nutrition when we say the need for nutrition it indicates the lack of lipids. As the skin protects by creating an impermeable layer, these lipids help the skin in this function by restoring cell membrane. Therefore, when lipids are decreased, the shielding function is enervated. And there is an increase in dehydration, loss of elasticity and the skin becomes susceptible and the result is wrinkles on face.
