There are skincare products available without a prescription that lighten the hyperpigmentation left by acne:
1. Hydroquinone works like a bleach to lighten skin, but is losing popularity because it causes skin irritation and has possible links to cancer.
2. Kojic Acid (a natural skin lightener from mushroom extract)
3. Arbutin (also known as bearberry extract)
4. Vitamin C (ascorbic acid) is another effective ingredient available in lightening creams. Learn more here: https://masterpieceskinrestoration.com/blog/acne-scar-treatment/
