Ablative lasers do which of the following?

• A. Heats skin without burning
• B. Destroys dermis (skin resurfacing)
• C. Cools the skin
• D. Burns only the hair follicles

Answer: (B)

Ablative lasers work by physically removing skin tissue. They ablate the surface layers, often reaching into the dermis, which creates a controlled wound that prompts the skin to heal with new collagen and smoother texture. This resurfacing effect is the defining feature of ablative lasers. In contrast, non-ablative lasers heat tissue without removing surface layers, and other options describe cooling or hair-targeting rather than tissue removal. So the best description is that ablative lasers destroy dermis (skin resurfacing).
