Name a common ingredient found in acne treatments.

Salicylic acid is a widely recognized ingredient in acne treatments due to its ability to exfoliate the skin, unclog pores, and reduce inflammation. It is a beta hydroxy acid (BHA) that penetrates the oil-filled pores, making it particularly effective for treating acne-prone skin. By promoting cell turnover and helping to keep pores clear, salicylic acid can help prevent the formation of new acne lesions while also treating existing breakouts.

This ingredient is often favored in over-the-counter acne products because it is effective in managing various types of acne, such as blackheads and whiteheads. Additionally, salicylic acid has anti-inflammatory properties, which can help reduce redness and irritation associated with acne.

While other ingredients like benzoyl peroxide, alpha hydroxy acids, and retinol are also utilized in acne treatment regimens, salicylic acid's specific action of penetrating the pores makes it a staple in acne management solutions.
