Product Summary

This product could be helpful for: Anti-aging and Moisturizing, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- Exfoliating acids (lactic acid 1.90% - 2.90% and lactic acid 5.80% - 8.80%). 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).
- Salicylic acid (1.25% - 2.50%). This is an oil-soluble exfoliating acid. Because of this property, it can work inside pores and help reduce the congestion. It has an anti-inflammatory effect and is used to treat acne. Because it is a quite strong exfoliator, be careful with using this product too often: it could result in over-exfoliation.
- Azelaic Acid (23.00% - 35.00%). This active can reduce hyperpigmentation. It also works helps against acne and clogged pores. Please note that Azelaic Acid is most effective against acne in concentrations between 10% and 20%.
- Potassium Azeloyl Diglycinate (1.50% - 2.30%). It is a derivative of Azelaic Acid. It is less studied than Azelaic Acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium Azeloyl Diglycinate is better soluble in water compared with Azelaic Acid. Because of this property, products with Potassium Azeloyl Digclycinate can have a nicer texture.
- Humectants (lactic acid 1.90% - 2.90%, sodium lactate 2.40% - 3.50% and lactic acid 5.80% - 8.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

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.

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: lactic acid, salicylic acid.

Moisturizing
What does the product description say?

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": lactic acid, sodium lactate.
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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
