Dehydration is due to the alteration of the action of hyaluronic acid and decreased sebaceous gland production.
Hyaluronic acid is found in the dermis and is capable of absorbing large quantities of water, storing it to hydrate our skin. It also feeds the fibroblasts, thereby stimulating collagen and elastin synthesis.
The sebaceous glands produce the sebum responsible for the hydro-lypid balance necessary for our skin.Effect: The corneous layer loses its ability to retain water. Result:
- The skin is rough and wrinkled.
- Loss of elasticity.
- Loss of tone.
