CIR Rating [ B ]

Lactic Acid is the most popular and the least aggressive acid among all the AHAs. Unlike Salicylic and Glycolic acids which can irritate your skin, Lactic Acid will hardly cause any problems. The combination of its soft action and effectiveness makes it a real brilliant. It exfoliates dead cells, makes the skin tone even, clears pores, kills bacteria, moisturizes the skin and helps to keep water, helps the cells to produce Hyaluronic Acid. It also works as a strong antioxidant and anti-aging component.

It's a great acid for getting familiar with the world of AHAs. If you want to start using "fruit acids" but struggling for some reason, try to use Lactic Acid first. If your skin accepts it well, you can try stronger acids.

Position 4

#4Citric Acid

Origin: natural
Role: Buffering agent, Chelating agent, Fragrance ingredient, Masking

EWG Rating [ 1 ]
CIR Rating [ A ]

Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.

It's an exfoliator, meaning it increases UV sensitivity of your skin. That's why it's very important to use sunscreen after it.
