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?

  1. ASalicylic acid
  2. BLanolin
  3. CHyaluronic acid
  4. DCollagen
Show answer & 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.

Salicylic Acid

A beta-hydroxy acid (BHA) that is oil-soluble, allowing it to penetrate sebum-filled follicles and exfoliate within the pore.

  • Exfoliates inside pores
  • Reduces sebum production
  • Anti-inflammatory properties
  • Ideal for oily and acne-prone skin

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