Acne is a common skin problem that affects both teenagers and adults. There are many skin care products available that treat acne, but its important to know what ingredients to look for. Here are some of the best acne-fighting ingredients according to the search results:

1. Benzoyl peroxide: This is a widely used acne treatment that is effective in treating and preventing acne. It works by killing acne-causing bacteria and reducing inflammation.

2. Salicylic acid: This ingredient is found in many over-the-counter and prescription skin care products. It helps to unclog pores and remove dead skin cells that can cause acne.

3. Adapalene: This is a retinoid that can help prevent new breakouts and unclog pores. Its available in different forms and strengths, including an over-the-counter 0.1% gel.

4. Azelaic acid: This naturally occurring compound has antibacterial and anti-inflammatory properties. It also helps prevent the buildup of keratin, a protein that can clog pores.

5. Alpha hydroxy acids (AHA): These acids treat acne by removing dead skin cells and reducing inflammation. They also improve the appearance of acne scars by stimulating the growth of new skin. Two types of alpha hydroxy acids found in acne products are glycolic acid and lactic acid.

6. Sulfur: This ingredient is often combined with other ingredients like benzoyl peroxide or salicylic acid. It removes dead skin cells that clog your pores and helps remove excess oil (sebum) that may cause breakouts.

7. Vitamin C: This is an antioxidant and has anti-inflammatory properties. It can help decrease redness and swelling in acne-prone skin.

8. Tea tree oil: This is an essential oil made from the leaves of the tea tree. A gel with 5% tea tree oil may be as effective on acne as one containing 5% benzoyl peroxide. But tea tree oil may not work as fast.
