Works for
Evens skin toneAzelaic acid, Glycolic acid + 1 moreWorks well
“Ducray Keracnyl Serum 30ml is a serum for adult blemish-prone skin which helps to eliminate spots and stubborn marks of first wrinkles.”
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: azelaic acid, 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.
Anti-agingGlycolic acid, Tocopherol + 1 moreWorks well
“It allows a triple action anti-imperfections, anti-marks and anti-ageing.”
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.
Anti-blemishAzelaic acid, Glycolic acid + 1 moreWorks well
“Myrtacine (Patented Innovation) allows to fight against P.Acnes bacteria by limiting its organisation in Biofilm.”
This product can help reduce breakouts and clogged pores because it contains the following ingredient: azelaic acid. This ingredient is used for treating acne and can have a noticeable effect.
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: glycolic acid
MoisturizingCaprylic/capric triglyceride, Glycerin + 6 moreWorks
“After use, the skin is moisturized, clearer and matified.”
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.
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: caprylic/capric triglyceride, dimethicone.
Anti-oxidationSide benefit · Azelaic acid, Myrtus communis leaf extract + 2 moreWorks well
This product contains antioxidants (azelaic 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).
ExfoliationSide benefit · Azelaic acid, Glycolic acidWorks 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.
