Skin can be hydrated at any age
"When I was young my skin didn't feel as dry as it does now."
The skin, just like the whole body, changes with age.
With age, and especially in post-menopausal women, the skin becomes thinner and drier, and sometimes desquamation appears in the form of thin scales.
Hydrating creams are particularly indicated for mature skin to maintain a healthy appearance, suppleness and also effective "functioning", which is called the barrier effect.
