Several acids can brighten skin by exfoliating dead cells, inhibiting melanin production, and promoting collagen production. These include:
- Glycolic acid: This alpha hydroxy acid (AHA) is known for its ability to slough off dead skin cells, revealing a brighter complexion. It can also directly inhibit melanin formation, helping to lighten dark spots.
- Lactic acid: Another AHA, lactic acid exfoliates the skin, revealing brighter skin. It also hydrates and plumps the skin, leading to a more youthful appearance.
- Azelaic acid: This acid can visibly brighten skin and improve the appearance of dark spots. It works by reducing melanin production and inflammation.
- Tranexamic acid: This acid is a potent brightening agent that reduces the appearance of dark spots and hyperpigmentation. It works by inhibiting the production of melanin.
- Phytic acid: This gentle AHA can exfoliate the skin and act as a melanin inhibitor, contributing to a brighter complexion.
- Niacinamide: While not technically an acid, niacinamide is a powerful ingredient that can brighten skin. It works by reducing melanin production and inflammation.
It's important to note that not all acids are created equal. Some acids are stronger than others, and some may be more suitable for certain skin types. It's always best to consult with a dermatologist to determine which acid is right for you.
