Non-ablative lasers do which of the following?

Non-ablative lasers do which of the following?

• A. Heat up skin without burning (skin rejuvenation)
• B. Destroy dermis (skin resurfacing)
• C. Remove hair
• D. Freeze tissue

Answer: (A)

Non-ablative lasers heat deeper skin tissues to stimulate collagen remodeling while leaving the outer surface intact. This controlled heating prompts the skin to tighten and improve texture over time, achieving rejuvenation without burning or removing surface skin. This matches heating the skin without burning for rejuvenation. In contrast, destroying the dermis describes ablative resurfacing that removes tissue; removing hair relies on targeting hair follicles, not just heating skin; and freezing tissue is not a laser effect.
