Why you need it:
The Ordinary Lactic Acid 10% + HA is a high-strength Alpha-Hydroxy Acid treatment that exfoliates surface levels of the skin, banishing dullness and revealing a brighter, fresher, more radiant complexion. It helps to treat skin that has been photo-damaged, stimulating collagen production and helping to lessen the appearance of fine lines and wrinkles. It brightens skin and helps to reduce hyperpigmentation from UV exposure, including dark spots, melasma and even freckles. It may even help to improve the appearance of acne scars . Because it removes dead cells from the skin's surface, it improves the effectiveness of your other skin care products,  letting them reach and deliver their benefits to the younger skin cells beneath.
