• A. It has no effect.
• B. It speeds up product absorption.
• C. It prevents exfoliation.
• D. It can worsen inflammation or hyperpigmentation.

Answer: (D)

Sun exposure is a concern after facial treatments because the skin is more sensitive and healing processes are activated. Treatments such as chemical peels, microdermabrasion, or laser can disrupt the skin barrier, making it more reactive to UV light. Ultraviolet exposure can trigger or worsen inflammation and stimulate excess melanin production as the skin tries to protect itself, leading to post‑inflammatory hyperpigmentation. This risk is why sun avoidance and using broad‑spectrum sunscreen (SPF 30+), along with protective clothing and limited sun exposure, are advised after a facial treatment. It’s not true that sun has no effect, speeds absorption, or prevents exfoliation; instead, it can worsen inflammation and pigment changes, which is why it’s a key precaution post-treatment.
