Product Summary
"Lierac - Hydragenist The Rehydrating Serum" is effective for: Evens skin tone, Anti-aging, Exfoliation and Moisturizing
Ingredient callouts
- This product contains acids (gluconolactone 1.60% - 2.00%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). PHAs (gluconolactone) especially are great for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
- Humectants (biosaccharide gum-1 0.30% - 0.60%, sodium hyaluronate 0.95% - 1.15%, urea 1.10% - 1.40%, trehalose 1.30% - 1.60% and glycerin 3.40% - 4.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
It plumps up the skin and smoothes the fine lines of dehydration.The molecular patch limits water evaporation by forming a protective film and allows continuous hydration.Rechargeable.All skin types, even sensitive.
Source: Cocoon Center
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains gluconolactone.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: serine.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
An amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles
Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: gluconolactone
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels.

It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
Exfoliation
This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: gluconolactone.

Naturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations
Moisturizing
What does the product description say?
Hydragenist The Rehydrating Serum
Source: From product name
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": biosaccharide gum-1, glycerin.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A product of bacterial fermentation. Can help attract water to the upper layer of the skin

Anti-oxidation
This product contains antioxidants (gluconolactone) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
