What is the role of exfoliation in maintaining skin clarity and how often should it be performed for different skin types?

• A. Removes dead skin cells to improve texture and absorption; oily/acne-prone skin 1-2 times weekly; normal skin 1-2 times weekly; dry/sensitive skin less frequently or avoid during flare-ups.
• B. Exfoliation should be daily for all.
• C. Exfoliation is unnecessary.
• D. Exfoliation should be nightly.

Answer: (A)

Exfoliation clears away the dull, dead surface cells so the skin looks brighter, feels smoother, and allows skincare products to absorb more effectively. The frequency should suit the skin’s balance and tolerance: for oily or acne-prone skin, about 1–2 times a week helps keep pores clear and reduces buildup without over-drying. For normal skin, the same 1–2 times weekly cadence works well to maintain clarity and enhance product absorption. For dry or sensitive skin, exfoliation should be less frequent and avoided during flare-ups to protect the skin barrier; if used, opt for a very gentle approach (low-strength chemical exfoliant or a mild physical exfoliant) and monitor for irritation. Daily or nightly exfoliation is generally too aggressive for most skin and can disrupt the barrier, causing redness and sensitivity. Always follow exfoliation with moisturizer and sunscreen to support barrier health.
