A client presents with an oily skin type, characterized by enlarged pores and a shiny appearance, particularly in the T-zone. Which of the following ingredients would be most beneficial to incorporate into their facial treatment to help regulate sebum production and minimize pore visibility?
- ASalicylic acid
- BLanolin
- CHyaluronic acid
- DCollagen
Show answer & explanationAnswer & explanation
Correct answer: A. Salicylic acid
Salicylic acid is a beta-hydroxy acid (BHA) known for its ability to penetrate oil, exfoliate within the pore, and reduce sebum production, making it ideal for oily and acne-prone skin.
Why the other options are wrong
- B. Lanolin is an emollient that can be comedogenic and is unsuitable for oily skin.
- C. Hyaluronic acid is primarily for hydration and would not address sebum regulation.
- D. Collagen is a protein used for anti-aging and firming, not sebum control.

Memory trick: Oily skin's solution is a BHA, clearing pores all the way!
