What is the expected outcome of using a BHA (Beta Hydroxy Acid) product?

Using a beta hydroxy acid (BHA) product is primarily intended to exfoliate the skin, particularly within the pores. BHAs, such as salicylic acid, have unique properties that allow them to penetrate oil and help dissolve the debris that can lead to clogged pores. This action not only aids in exfoliating dead skin cells but also helps to reduce acne breakouts by preventing the formation of comedones (clogged pores) and controlling excess sebum production. Therefore, the expected outcome focuses on deep pore cleansing and minimizing acne, making this option the most appropriate answer.

In contrast, while hydration and moisturizing are crucial for skin health, those outcomes are not the primary function of BHA products. Instead, they can sometimes cause mild dryness as they work to exfoliate. The brightening effect, while potentially achievable through exfoliation, is more commonly associated with other ingredients like AHAs (alpha hydroxy acids) that work on the skin's surface rather than inside the pores. Consequently, using BHA specifically targets clearer and healthier skin by addressing acne through its exfoliating capabilities.
