We Know the Best Hyaluronic Acid Face Serum – See the Expert Opinions!

Youthful, perfectly-moisturized, wrinkle-free skin? Cosmetologists believe there is just one substance able to give you this effect. Hyaluronic acid is a favorite substance in the esthetic medicine because it smoothes wrinkles by filling the intercellular spaces, boosting elasticity and plumping the skin. Moreover, HA lessens the visibility of scars and spots. It makes a perfect face-care substance so – according to experts – a fine hyaluronic acid serum is one of the essential products giving striking and spectacular effects.

Hyaluronic acid – a polysaccharide which binds water in the dermis and supports collagen and elastin fibers. It keeps skin elastic and young. Over time its level diminishes, which sparks the appearance of wrinkles and sagging. Cosmetologists recommend incorporating HA into daily skin care routine as soon as we hit 25.

Why should we use hyaluronic acid serum?

Currently hyaluronic acid is the most powerful hydrating molecule which fills the intercellular spaces. It works like a natural facelift so you don’t need injections to improve the condition and “quality” of the skin. Regularly-used serum rich in a proper form of HA is like the key to youthful look – firm, elastic, radiant skin boasting the optimal hydration.


Regular application of hyaluronic acid gives you:

  • hydration
  • smoother skin
  • plumper face
  • flawless skin
  • end of wrinkles
  • ideal skin’s density
  • damage-proof skin
  • hydro-lipid balance

Low, medium or high molecular weight? What’s the difference?

This is simple. Hyaluronic acid has different names because it has different sizes of molecules. The smallest ones are the best because they can reach the deepest layers of skin. Large molecules of HA stay on the surface instead. Low molecular weight is the best form that skin experts swear by.
