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.
Evens skin toneGlycolic acid, Alpha-arbutinWorks well
“Benefits Helps fade spots and splotches aggravated by hormones, sun, or UV exposure. Naturally derived brightening agents.”
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: alpha-arbutin, 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.

Ingredient callouts
- Exfoliating acids (glycolic acid 3.50% - 5.30%). 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.
- Peptides (oligopeptide-34 5.00% - 7.50%). 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.
- In addition, this product contains Allantoin (0.85% - 1.30%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
