Key actives
Product Summary
"Prequel - MULTI-ACID MILK PEEL AHA EXFOLIATING SOLUTION" is effective for: Anti-aging, Exfoliation and Evens skin tone
This product could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Exfoliating acids (glycolic acid 5.20% - 6.40%, lactic acid 0.50% - 0.70% and mandelic acid 0.55% - 0.85%). In this concentration, they will have a noticeable exfoliating effect. They can also have an anti-aging effect and stimulate collagen production in a long-run. Lactic Acid can also help to attract water to the upper layer (works as a humectant).
- Humectants (glycerin 3.00% - 3.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Anti-aging
What does the product description say?
smooth the look of fine lines and wrinkles
Source: N/A
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.
An alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
Evens skin tone
What does the product description say?
brighten the look of dark spots
Source: N/A
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glycolic acid, mandelic 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.

Helps shed the upper layer of dead cells from the surface of the skin revealing smoother, brighter skin. It can help to reduce hyperpigmentation. It has anti-bacterial properties, and might help to reduce blemishes, as well as fine lines and wrinkles. It is considered to be gentler than glycolic acid

Exfoliation
What does the product description say?
exfoliates
Source: N/A
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, mandelic acid.

Moisturizing
What does the product description say?
softens and hydrates
Source: N/A
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: squalane, tricaprylin.
Helps soften the upper layer of the skin
An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.

Anti-blemish
This product contains ingredients (glycolic acid, mandelic acid) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.
