Works for

Anti-aging

Adenosine, 3-o-ethyl ascorbic acid + 1 more

Works well

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

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.

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.05–0.2%

3-o-ethyl ascorbic acidEffect: LowA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.3–2%

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~0.15–0.6%

Moisturizing

Glycerin, Glucosyl hesperidin + 11 more

Works

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.

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).

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~2–3%

Glucosyl hesperidinKey active· HumectantEffect: MediumMight be able to neutralize free radicals in skin. Also works as a humectant~0.85–1.3%

Glycine soja oilUnder-dosedA good emollient that helps soften the skin and helps repair its barrier function. It can clog pores if used in high concentrations.~0.05–0.15%

Evens skin tone

3-o-ethyl ascorbic acid

May help

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: 3-o-ethyl ascorbic acid.

3-o-ethyl ascorbic acidKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.3–2%

Exfoliation

No ingredient credited for this claim

Not delivered

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.

Anti-blemish

No ingredient credited for this claim

Not delivered

Effective ingredients missing or their concentration is too low.

Anti-oxidation

Not advertised by the brand · 3-o-ethyl ascorbic acid, Ascorbyl methylsilanol pectinate + 4 more

May help

This product contains antioxidants (3-o-ethyl ascorbic acid) 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.

Ascorbyl methylsilanol pectinateEffect: LowA stable derivative of pectin and vitamin C. It might help neutralize free radicals in skin, but evidence of effectiveness is lacking. Helps create a thicker product consistency and stabilize the product formulation~4.5–6.7%

Glucosyl hesperidinEffect: LowMight be able to neutralize free radicals in skin. Also works as a humectant~0.85–1.3%

AdenosineEffect: LowMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.05–0.2%

BisabololEffect: Low, below effective doseAn active component of chamomile plant that historically has been used to calm down irritated skin. A recent study shows that bisabolol indeed can have some anti-inflammatory effect on skin, even though conclusive data is lacking. Bisabolol has a sweet floral scent and can be added to products for its aromatic properties~0.05–0.15%

TocopherolUnder-dosedPure 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~0.15–0.6%

Product summary

"Novexpert - Sérum Booster à la Vitamine C" is effective for: Anti-aging

This product could be helpful for: Moisturizing and Evens skin tone, but its actives are not the most effective or are not well-studied.

Ingredient callouts

Adenosine 0.05% - 0.20%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
Humectants (sodium lactate 0.10% - 0.30%, sodium hyaluronate 0.30% - 0.70%, sodium pca 0.50% - 1.10% and glycerin 2.00% - 3.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
