7 reasons to choose Exar Hyaluronic Acid (HA) serums:

  • MOISTURIZATION: each serum helps to improve skin texture and brightness with intense moisture and balance.
  • ANTIAGE BENEFITS: anti-aging properties, they diminish the look of fine lines and wrinkles thanks to the moisturizing action
  • VISIBLE EFFECTS: you will start seing plumper, softer and smoother skin.
  • GENTLE & EFFECTIVE, including those with sensitive skin.
  • Paraben-free, glycerin-free, oil-free, no dyes, no fragrances or fillers.
  • High concentration (from 1% to 2%, according to what is indicated on the label)
  • Clinically proven and dermatologist tested.

For your skin all the freshness and hydration of the latest Exar cosmetic line based on concentrated hyaluronic acid (HA) at low, medium and high molecular weight.

Three concentrated hyaluronic acid serums: natural and biotechnological like beer! Our hyaluronic acid, in fact, is produced through the fermentation of barley and other grain, naturally secreted by the bacillus subtilis.

Our HA (hyaluronic acid) serums are high quality products studied for topical application on face. Getting older our skin before losing elasticity loses hydration. The hyaluronic acid is a valid humectant (J. N. Kraft et al. "Moisturizers: What They Are and a Practical Approach to Product Selection", Skin Therapy Letter, vol. 10 No. 5, June 2005), this means it draws water to the skin and helps prevent moisture loss, that's how it helps to fight the excessive skin water loss, ensuring an intensive moisturizing action, helping the skin to maintain and recover the proper hydration. 

Remember that "moisturizers play a role in treating and augmenting therapy for the aging face" ((Glaser DA, Rogers C. Topical and systemic therapies for the aging face. Facial Plast Surg Clin North Am 9(2):189-96 (2001 May)), so the hyaluronic acid serums

Last but not least, there is also some evidence that hyaluronic acid stimulates collagen production (Greco, Rita M., Joseph A. Iocono, and H. Paul Ehrlich. "Hyaluronic acid stimulates human fibroblast proliferation within a collagen matrix." Journal of cellular physiology 177.3 (1998): 465-473).
Furthermore, the hyaluronic acid is a glycoprotein highly biocompatible: its usage ensures an very high rate of safety, avoiding any allergy risk.

The hyaluronic acid, thanks to the enormous length of its molecule and its moisturizing power, arranges itself in the space creating a special structure that works like a "molecular scaffolding" able to make the skin tissue maintain its shape and tone. This is the most interesting feature of hyaluronic acid in the cosmetic field.

For an immediately better moisturized kin. A fresher face from any point of view.

You just need to massage the chosen HA serum on your skin, no injection!


The key properties of Exar hyaluronic acid:

1) The high concentration. The hyaluronic acid we use in our serum hasn't been diluted neither with glycerin nor with other active principles able to influence the viscosity of the final product. The viscosity of our HA serums is totally defined just by the hyaluronic acid. Each serum, in fact, is a pure solution of water and sodium hyaluronate (hyaluronic acid). That's why each serum has to be used pure: never mix it with any other product if you want to maintain its action and avoid to unbalance its formulation.
2) The very low bacterial count. For the user's safety we check it carefully for any batch.
3) Our hyaluronic acid serums are clinically proven and dermatologist tested.
4) Our hyaluronic acid serums contains just two preservatives, both eco certificated. Nothing else.

All these features are at the heart of the high quality and antiageing skin care properties of our hyaluronic acid serums.

While choosing your hyaluronic acid serum consider always this: the smaller is the HA molecule, the deeper it goes into the skin; the bigger is the HA molecule the more visible are the effects as you are working more on the surface of the skin.

The low molecular weight hyaluronic acid penetrates deep into the skin where it exerts a powerful moisturizing action and contributes even to the elastin production. It works as a humectant and stimulating agent for collagen synthesis and cell proliferation. Its effects on skin? The low hyaluronic acid increases skin moisturizing starting from its deepest layers, thus it can change the skin complexion, giving also a new light to your skin, while it works by preventing water loss.

The medium molecular weight hyaluronic acid can bind to more water than the low molecular weight hyaluronic acid but it cannot enter so deep into the skin due to its bigger size. The fact of being absorbed more on the surface of the skin makes the medium HA able to produce interesting aesthetic effects, contributing to less visible wrinkles more than the low HA.

The high molecular weight hyaluronic acid has the ability to bind bigger amount of water thanks to its structure. Its high molecular weight doesn't allow deep skin penetration, this HA produces a more superficial action on the skin compared to the medium and the low molecular weight HA. Working so much on the surface of the skin means this hyaluronic acid can produce even more visible effects on wrinkled skin, that will look smoother and softer thanks to the strong skin surface moisturizing.

Anyhow, to exploit the properties of the serums we sugget you to exploit the synergy you can obtain from using the different molecular weight hyaluronic acid serums in sequence. In this way - applied one after the other (no blending them together) - the different HA serums can work on different skin layers, ensuring a valid action on the whole skin, contributing to a younger looking skin and an enlightened complexion.
