External agents including benzoyl peroxide, retinoids, and oral antibiotics are most effective in treating acne. There is no proven effectiveness of changing your diet and taking dietary supplements. The press service reports that American Academy of Dermatology (AAD).
An AAD expert panel revised acne treatment guidelines adopted in 2016. New guidelines recommend using topical benzoyl peroxide to suppress acne-associated bacteria. Instead of or in combination with them, you can use topical products with retinoids (adapalene, tretinoin, tazarotene, and trifarotene)—they help clear pores and reduce inflammation.
Oral antibiotics such as doxycycline may also be helpful. However, these medications should be used only when needed because overuse can lead to the development of treatment-resistant bacteria. A combination of oral antibiotics and topical benzoyl peroxide may reduce this risk.
Patients with severe acne that does not improve with topical treatment may need to take medications containing isotretinoin.
Hormonal therapy, including the use of birth control pills or spironolactone, can also improve acne if it is caused by hormonal problems. Other effective ingredients of external products include salicylic and azelaic acids.
Chemical peels, lasers, topical adapalene gel (0.3%), and light therapy have not been proven effective and require further study. Diets and nutritional supplements are not included among the recommendations for acne treatment.
