Source: Beautylish

This product can help reduce breakouts and clogged pores because it contains the following ingredient: salicylic 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

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

“Potent 10% Glycolic Acid Complex, Licorice and Arnica help reduce the appearance of uneven skin tone and texture.”
Source: Beautylish

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid, salicylic 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: glycyrrhiza glabra root extract.

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.

What the product description says
“A 10% Glycolic Acid Complex (AHA), Licorice and Arnica help reduce the appearance of fine lines, wrinkles, acne marks and residual discolorations.”
Source: Ulta

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.

What the product description says
“10% Glycolic Acid (AHA) exfoliates surface dead skin cells and stimulates cellular turnover.”
Source: Bluemercury

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, salicylic acid.

What the product description says
“Hydrates and helps calm the look of skin.”
Source: Sephora CA

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: arginine, 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: arginine, isododecane.

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~2.7–3.3%
ArginineKey active· Humectant, OcclusiveEffect: HighAn amino acid that is naturally present in skin and helps keep it hydrated. When used together with AHAs, it can reduce their irritating effect on the skin~2.2–2.7%
IsododecaneKey active· Emollient, OcclusiveEffect: MediumAn emollient that helps soften the skin and can decrease moisture loss. Helps create a nice product texture~1.5–1.8%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~1.5–1.8%
Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.45–0.65%
