How does sun exposure affect facial treatments and post-treatment care recommendations?

• A. Increases risk of hyperpigmentation and sensitivity; SPF 30+, avoid UV exposure after aggressive treatments, and monitor pigment changes.
• B. Sun exposure has no effect on facial treatments.
• C. Sun exposure speeds up healing after treatments.
• D. Only UV exposure at noon matters.

Answer: (B)

Sun exposure affects facial treatments because the skin becomes more sensitive and reactive after procedures, and UV light can worsen inflammation and trigger pigment changes. After treatments like chemical peels or laser work, the risk of post-inflammatory hyperpigmentation increases if you’re in the sun, so protecting the skin is essential. Post-treatment care typically emphasizes minimizing sun exposure and applying broad-spectrum sunscreen (usually SPF 30 or higher) daily, reapplying when outdoors, and using protective clothing or a wide-brimmed hat. It’s also common to avoid aggressive exfoliants or retinoids for a period and to follow the clinician’s guidance on when to resume normal skincare. The idea that sun exposure has no effect isn’t accurate; protection is a key part of achieving the best results and reducing adverse changes, and UV exposure should be managed year-round since UVA and UVB can impact healing even on cloudy days.
