Decoding cosmetology: Hyaluronic acid

This post is also available in: Français

It’s the must-have anti-aging agent and top moisturizing ingredient. However, this superstar is nothing new—we’ve known about it since 1934. Seventy-five years after its discovery, it’s as fresh as ever!

Hyaluronic acid helps replenish skin’s moisture reserves. Moisture protects skin from daily aggressions and helps cells function. Without it, skin withers, dries out, and becomes thinner. Facial features become more pronounced, wrinkles appear, and skin loses its plumpness.

Like a sponge, hyaluronic acid molecules can absorb up to 1,000 times their own weight in water. Imagine a kind of jelly: by transforming the absorbed water into a gooey fluid, it restores skin density and plumps the underlying flesh.

Our star molecule takes on several guises

Depending on your needs and the areas you want to treat, hyaluronic acid comes in different forms.

In the form of an injectable gel, hyaluronic acid is crosslinked to various degrees. Simply put, cross-linkage helps form “bridges” that link molecules together. Highly crosslinked or very compact and viscous hyaluronic acid serves to restore and contour the cheeks or chin, for example, and is injected deeply into the skin.

Moderately crosslinked or compact hyaluronic acid is used to fill in smile lines, correct the oval of the face, and restore lip volume. It is injected into the middle or deep epidermis.

In cosmetic products, hyaluronic acid is formulated with different molecular weights, which allows it to penetrate the skin barrier and settle in the desired area to perform a variety of targeted actions consistent with the results sought.

Premiology HA4 Technology

The basic principle of this cosmetic line is targeted wrinkle reduction and deep skin hydration through a combination of four forms of hyaluronic acid that work together.

High molecular weight hyaluronic acid and vectorized high molecular weight hyaluronic acid (with spherulites) contained in Premiology products provide progressive action over a six-hour period. They smooth the skin surface, fill in wrinkles and vertical creases, restore volume and plumpness, re-densify skin, and re-establish the moisture balance.

Micro-fragmented hyaluronic acid promotes water retention in the skin, stimulates collagen and elastin formation, and increases skin firmness and elasticity. It smoothes the skin surface and fills in wrinkles and creases.

Lastly, HA precursor reactivates the natural formation of hyaluronic acid to volumize and fill in from within. It promotes water retention in the skin, stimulates cell regeneration, and reduces the appearance of wrinkles and vertical creases.

The addition of plant-derived active ingredients further boosts skin regeneration by stimulating collagen, evening out skin tone, and enhancing anti-inflammatory and antioxidant action.

Toned skin for standout eyes
