- AHyaluronic acid
- BHydroquinone
- CBenzoyl peroxide
- DSalicylic acid
Show answer & explanationAnswer & explanation
Correct answer: B. Hydroquinone
Hydroquinone is a powerful skin-lightening agent that works by inhibiting tyrosinase, an enzyme essential for melanin production. It is highly effective for treating hyperpigmentation and uneven skin tone, often prescribed by dermatologists.
Why the other options are wrong
- A. Hyaluronic acid is a humectant used for hydration, not for treating hyperpigmentation.
- C. Benzoyl peroxide is an antimicrobial and keratolytic agent used for acne, not for melanin inhibition.
- D. Salicylic acid is a BHA, primarily used for acne and exfoliation, not directly for inhibiting melanin production.
