Kiehl's Clearly Corrective Accelerated Clarity & Renewing Ampoules
Works for
Evens skin toneGlycolic acid, 3-o-ethyl ascorbic acid + 1 moreWorks well
“Our brightening ampoules programme is precisely formulated to work in harmony with our Clearly Corrective Dark Spot Solution to effectively target signs of clarity loss, including dullness and uneven skin tone, and promote surface skin cell renewal.”
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: 3-o-ethyl 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.
Anti-agingSide benefit · Glycolic acid, 3-o-ethyl ascorbic acid + 1 moreWorks well
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.
ExfoliationSide benefit the brand mentions · Glycolic acid, Lactic acidWorks well
“, Glycolic, Lactic, and Phytic Acids Promotes visible skin renewal for brighter-looking skin and a smooth texture.”
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.
Anti-oxidationSide benefit · 3-o-ethyl ascorbic acid, Bisabolol + 1 moreMay help
This product contains antioxidants (3-o-ethyl ascorbic acid) that can help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is some human evidence for this effect in skin, though it is smaller or less consistent than the evidence for the best antioxidants.
MoisturizingSide benefit · Isopropyl myristate, Glycerin + 2 moreWorks
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: isopropyl myristate, pentylene glycol.
