AHA
What it is
An alpha hydroxy acid (AHA) derived from bitter almonds. It has a larger molecular size than other AHAs, making it a gentler option.
How it works
Like other AHAs, it exfoliates by dissolving the bonds between dead skin cells. Its larger molecular size means it penetrates the skin more slowly and evenly, resulting in less irritation. It is also oil-soluble and has natural antibacterial properties.
Benefits
- Provides gentle exfoliation, suitable for sensitive skin.
- Helps to treat acne due to its antibacterial properties.
- Improves hyperpigmentation, particularly post-inflammatory hyperpigmentation.
- Can help regulate sebum production.
