Which of the following is NOT a primary benefit of salicylic acid in skincare?

Salicylic acid is well-known for its various benefits in skincare, particularly for treating acne and oily skin. Among its primary benefits are its keratolytic effects, which involve the thinning and exfoliation of the outer layer of the skin, helping to clear clogged pores and reduce acne lesions. Additionally, salicylic acid possesses antiseptic properties that can help prevent infections and bacterial growth on the skin. It also has antibacterial benefits, which contribute to its effectiveness in treating acne by targeting bacteria that can lead to outbreaks.

However, the claim that salicylic acid increases moisture retention is not a primary benefit. Salicylic acid is actually known to have a drying effect on the skin, especially at higher concentrations, as it helps to exfoliate and remove excess oil. While it can indirectly improve skin texture and clarity, it does not directly enhance moisture retention like hydrating ingredients such as hyaluronic acid or glycerin do. Therefore, this aspect distinguishes moisture retention from the primary benefits of salicylic acid.
