Ingredient callouts
- This product also contains Vitamin C (Ascorbic Acid) 4.50% - 6.70% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
- Peptides (acetyl dipeptide-1 cetyl ester 0.05% - 0.20%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
- Adenosine 0.05% - 0.20%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
- Humectants (hydrolyzed hyaluronic acid 0.05% - 0.25%, sodium hyaluronate 0.05% - 0.25% and glycerin 2.00% - 3.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Benefits
Promise: Anti-blemish
What does the product description say?
82% pores are tightened.
Effective ingredients missing or their concentration is too low.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| salicylic acid | HIGH |  |  |
Promise: Anti-aging
What does the product description say?
Enriched with 10% pure vitamin C, otherwise known as ascorbic acid, this biologically active form of vitamin C will brighten, stimulate collagen production and reduce the damage of free radicals.
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid, 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.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| ascorbic acid | HIGH |  | |
| adenosine | HIGH | | |
| acetyl dipeptide-1 cetyl ester | MEDIUM | | |
Promise: Evens skin tone
What does the product description say?
Ideal for those with wrinkles, dull skin and uneven tone, the fresh, non-greasy essence melts quickly into skin, releasing a surge of beneficial ingredients to leave the face feeling softer, more hydrated and glowing.
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic 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.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| ascorbic acid | HIGH | | |
| salicylic acid | LOW | | |
Promise: Exfoliation
What does the product description say?
45% salicylic acid will smooth and exfoliate away dead skin cells, while a duo of neurosensine and La Roche-Posay’s own thermal spring water will eliminate inflammation, soothe redness and relieve sensitivity.
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.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| salicylic acid | HIGH | | |
Promise: Moisturizing
What does the product description say?
Rich serum texture leaves skin feeling softer & more hydrated.
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, hydrolyzed hyaluronic acid.
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: dimethicone, c13-14 isoparaffin.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| dimethicone | HIGH | | |
| polymethylsilsesquioxane | HIGH | | |
| hydrolyzed hyaluronic acid | HIGH | | |
Other benefit: Anti-oxidation
This product contains antioxidants (ascorbic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| ascorbic acid | HIGH | | |
| adenosine | LOW | | |
| tocopherol | HIGH | | |
