Known for its long-standing use in cosmetics, hyaluronic acid is recognized for its benefits on the skin. All skin types benefit from its properties, the number one action is to hydrate intensely : in fact hyaluronic acid is capable of retaining 1000 times its weight in water ! It will also plump the skin, smooth wrinkles and fine lines but also control sebum production.
Understanding hyaluronic acid
Hyaluronic acid is a molecule present in skin tissues, representing between 50 and 70% of their composition, varying depending on the depth of the different layers of the skin. It captures water from the body and maintains it.
It has the same role as collagen and elastin and helps form the structure of the skin. But like any other molecules, its production weakens during skin aging, giving way to a loss of elasticity, firmness and the appearance of wrinkles and fine lines. By the age of 50, its quantity is halved.
It can have different origins:
- Human body: it is naturally present in the dermis.
- Synthetic: Made mainly from cockscombs. When synthesized it gives a thick and transparent gel, the properties it provides are almost identical to natural hyaluronic acid.
- Natural: Obtained from plant origin with wheat. The powder form of hyaluronic acid, once mixed with water, transforms into a dense and transparent gel that shares the same characteristics as its synthetic version.
The benefits of hyaluronic acid serum
A hyaluronic acid- based serum should be one of the products to include in a beauty routine from a certain age because it ensures several actions on the skin:
- Deep hydration of the skin
The benefits of hyaluronic acid serums provide intense hydration to the skin while preserving the extracellular matrix. Particularly connective tissue, which gives the skin a plump appearance.
- Reduction of fine lines and wrinkles
However, you shouldn't have any false ideas either, because even if hyaluronic acid provides benefits, it will not miraculously remove wrinkles. It will act, depending on its molecular weight and its concentration, on reducing the signs of aging and giving a plumping appearance to the skin!
- Improved skin elasticity.
Its action will also take place at the level of the elastin fibers in the skin, acting like a sort of sponge allowing it to maintain its elasticity.
- Anti-inflammatory and healing effects
It will promote the production of new skin cells and accelerate the healing process. This helps reduce redness, swelling and irritation. The reinforcement it provides to the skin barrier prevents infections and protects the skin from harmful environmental influences.
