What is hyaluronic acid?
Naturally present in the intercellular spaces of the dermis, hyaluronic acid plays an important role in our body. In addition to hydrating and protecting the skin from the outside environment, it can retain up to 1,000 times its weight in water. It contributes to the reconstruction of the skin’s structure and allows the skin to maintain its firmness and elasticity. Over time, its quantity in the body decreases; it is estimated that we lose about 6% of hyaluronic acid every year. This lack of hyaluronic acid leads to a loss of skin elasticity and the appearance of wrinkles. It is therefore important to choose a cream and serum composed of hyaluronic acid to hydrate and plump the skin as well as smooth wrinkles.
The different types of hyaluronic acid
However, there are two types of hyaluronic acids that do not have the same size and therefore have different effects for the skin.
- High molecular weight hyaluronic acid
This type of hyaluronic acid contains the largest molecular size. It acts on the surface of the dermis, forming a translucent protective film and does not penetrate the skin barrier. It allows water to be retained in the cells and therefore thoroughly hydrates the skin. It is the perfect ally for skin in the early stages of aging.
- Low molecular weight hyaluronic acid
This is a micro-molecule that penetrates deep into the skin thanks to its small size. Its mission? Act on the layers of the epidermis, boost collagen production and plump skin from the inside.
In short, hyaluronic acid is an essential active ingredient for all those who wish to care for their skin throughout their lives.
