The best products for clearing acne can vary based on the severity and type of acne, as well as an individual's skin type and sensitivity. However, here are some over-the-counter (OTC) products that are commonly used for treating acne: Benzoyl peroxide: Benzoyl peroxide is a powerful antimicrobial agent that helps kill the bacteria that contribute to acne. It is available in creams, gels, and washes. Salicylic acid: Salicylic acid is a type of beta-hydroxy acid that can help unclog pores and exfoliate dead skin cells. It is available in gels, creams, and toners. Alpha-hydroxy acids (AHAs): AHAs, such as glycolic acid, are exfoliating agents that can help unclog pores and reduce the appearance of acne scars. They are available in creams, gels, and toners. Niacinamide: Niacinamide is a form of vitamin B3 that has anti-inflammatory properties and can help improve the skin's barrier function. It is available in creams and serums. Tea tree oil: Tea tree oil has antibacterial properties that can help kill the bacteria that contribute to acne. It is available in pure oil form or as an ingredient in creams and gels. It's important to note that these OTC products may not work for everyone and that some products may not be appropriate for everyone, especially if you have sensitive skin or are taking any medications. If your symptoms persist or worsen, it's best to consult with a doctor to determine the best course of treatment for you. Additionally, it's important to follow the instructions on the product label and to use sun protection when using products that can increase skin sensitivity.
