Hyaluronic Acid (otherwise referred to as HA) is an ingredient that can be found in an increasing number of skin care products geared towards increasing hydration and boosting the effectiveness of daily moisturizers.
Its helps to store water in the skin, providing essential moisture to body processes
A substance naturally found in the body, Hyaluronic Acid works to absorb water and lubricate skin tissue. Young skin contains high levels of this chemical and as a result appears full, plump and smooth. As we age, our levels of Hyaluronic Acid decrease, resulting in fine lines, wrinkles and loss of elasticity.
Skin loses elasticity and becomes dry because moisture is lost and that’s because hyaluronic acid in between your cells have decreased. To keep skin hydrated, it’s important to have hyaluronic acid at optimal levels.
HA can hold hundreds of times its weight in water and is often used in moisturizing formulas.
As derived from here, HA works by attracting moisture from the air and sealing it into our skin. However if you live in a relatively dry climate, the usage of hyaluronic acid alone might cause skin dehydration. The reason is that when there isn't enough moisture in the air, hyaluronic acid will instead take moisture from you skin to seal them on the surface. So if you decide to use a hyaluronic acid in a dry climate, make sure you have a face spray with you at all time. That will solve the dilemma.
Hyaluronic acid has many functions throughout the body, especially in the connective tissue. In the skin, some of its known roles are the following:
- Holding moisture
- Increasing viscosity and reducing permeability of extracellular fluid
- Contributing to mechanical resilience and suppleness of the skin
- Regulation of tissues repair
- Regulation of movement and proliferation of cells
- Regulation of immune and inflammatory responses
