Which laser type is associated with heating the skin to rejuvenate without removing tissue?

• A. Ablative lasers destroy the dermis
• B. Non-ablative lasers heat the skin without burning (correct)
• C. Ablative lasers cool the skin
• D. Non-ablative lasers peel the epidermis

Answer: (B)

The idea being tested is how different lasers affect skin tissue. Non-ablative lasers heat deeper skin layers to stimulate collagen remodeling and rejuvenation while leaving the surface epidermis largely intact. This controlled heating improves skin texture and tone without removing tissue, which is why downtime is typically shorter than with resurfacing lasers that actually ablate tissue. Ablative lasers, by contrast, remove tissue from the surface or deeper layers, causing more healing time and a wounding effect. Saying a non-ablative laser peels the epidermis would imply tissue removal, which isn’t the case. So heating the skin without removing tissue is the correct approach for rejuvenation with minimal surface damage.
