What the product description says
“Lierac, Hydragenist A delicious melt-in formula, this oxygenating serum plumps the skin for a more youthful appearance.”
Source: Allbeauty

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains glycolic acid.

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.

Glycolic acidKey activeEffect: HighAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid~0.2–0.35%
Sodium salicylateEffect: LowThe salt of salicylic acid. Helps exfoliate the upper layer of the skin. Can also work to preserve cosmetic products~0.15–0.3%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.2–0.35%
Zinc gluconateEffect: Low, below effective doseTypically used to stabilize the product formulations. It is a salt of a polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing. Due to the zinc content, might help calm down inflammation in skin~0.2–0.35%
Copper gluconateEffect: Low, below effective doseTypically used to stabilize the product formulations. It is a salt of polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin.

Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.2–0.35%
Retinyl palmitateUnder-dosedThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.15–0.3%

What the product description says
“Hydragenist Moisturizing Serum”
From product name

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. 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. The following ingredients in this product do the job: glycerin, glycine.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethiconol, helianthus annuus seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea

UreaHero· HumectantEffect: HighNaturally 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~1.4–1.7%
CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~3.9–4.8%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~2.9–3.5%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.1–1.4%
DimethiconolKey active· Emollient, OcclusiveEffect: HighA silicone that makes products more spreadable and keeps skin smooth. Helps to add gloss to skin and may visually fill in fine lines/wrinkles for short time~0.9–1.1%
GlycineKey active· HumectantEffect: HighHelps to attract water to the upper layer of the skin and can help restore the skin barrier function~0.3–0.5%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.25–0.45%
Sodium lactateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product~0.25–0.45%
Manganese gluconateKey activeEffect: HighMight be able to help restore skin barrier function supporting its hydration~0.2–0.35%
Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.2–0.35%
Cyclohexasiloxane· EmollientEffect: LowA silicone that serves as an emollient. Helps create a nice non-greasy feels~1.9–2.4%

Evens skin tone
Side benefit · Glycolic acid, Zinc gluconate + 3 more
Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid

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.

Glycolic acidKey activeEffect: HighAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation.

Exfoliation
Side benefit · Urea, Glycolic acid + 4 more
Works well

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: glycolic acid.

UreaKey activeEffect: MediumNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin.

Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect

Ingredient callouts

  • this product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.15% - 0.30%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • Humectants (urea 1.40% - 1.70%, glycine 0.30% - 0.50%, glycerin 2.90% - 3.50%, sodium pca 0.25% - 0.45%, sodium lactate 0.25% - 0.45% and sodium hyaluronate 1.10% - 1.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
