Hyaluronic acid: you've been saying its name since it first appeared in your creams in 1996, and you probably use it every day. But do you really know what it is, what it's used for, or how many types there are?
Hyaluronic acid is a sugar molecule naturally present in our bodies. However, starting at age 25, it begins to gradually be lost, which is evident in the skin, which gradually loses its plumpness, hydration, and firmness.
Benefits of hyaluronic acid.
Did you know that nearly 50% of the total hyaluronic acid in our body is concentrated in the skin? Yes, and it's responsible for performing important functions such as these:
- Helping skin cells survive longer by thickening the epidermis and preventing the buildup of dead skin.
- Protect the epidermis by blocking free radicals generated by exposure to ultraviolet (UV) radiation.
- Hyaluronic acid also acts as an intermediary between collagen and water in our skin. Therefore, when it is depleted, cells can no longer retain enough water, and collagen degenerates. This leads to a loss of elasticity and firmness, and consequently, to the appearance of wrinkles and loss of volume.
Dermatologists and facialists agree in recommending its daily use. It's a very versatile ingredient that adapts to all skin types with zero risk of irritation and can also be used both morning and night.
Still unsure about the need for an external dose of hyaluronic acid? If you're confused by the terms "high or low density," "cross-linked or non-cross-linked," or the different concentrations available in cosmetics, you should read on.
How many types of hyaluronic acid are there?
High-molecular-weight hyaluronic acid . It's contained within large molecules, so it has a higher density. It doesn't penetrate the skin as deeply, but it's safer and more stable. Its action is primarily hydrating, as it's a film-forming agent that keeps water bound to the skin and prevents its loss by sealing the barrier function.
Low molecular weight hyaluronic acid . It penetrates deeper into the epidermis and its primary action is biological. It activates the skin's natural defense system through the production of beta-defensins (peptides that function as natural antibiotics). Furthermore, this density shows better results when it comes to skin regeneration.
Very low molecular weight hyaluronic acid . It has a primarily anti-aging effect and can be used as a non-invasive alternative to injections. It stimulates cell cohesion, promotes the synthesis of procollagen (a collagen precursor that repairs the connective tissue that supports the skin), and reduces roughness while promoting the synthesis of endogenous hyaluronic acid (the kind we naturally produce).
Crosslinked or encapsulated hyaluronic acid: what's the difference?
Hyaluronic acid reticulated It is an elastomer (a polymer with elastic properties) of hyaluronic acid that, when cross-linked, forms a three-dimensional structure on top of the skin, protecting it from damage caused by UV rays and pollution. At the same time, it has a long-lasting moisturizing effect, as its activity lasts longer.
Its function is similar to that of a very high molecular weight hyaluronic acid. It forms a 3D mesh-like film on the face that improves the barrier function and reduces water evaporation from the skin.
Another option is that it is encapsulated . In this case, their release is slow and, in addition to hydrating, they have a filling effect on either wrinkles or lips.
The best cosmetic treatments often use different types of hyaluronic acid to address all skin issues. But be careful, as the effects below 1% concentration may not be as expected.
