Ablative lasers produce an obvious disruption to the skin, i.e., at the very least the epidermis is no longer intact and the skin is denuded. Non-ablative lasers do not produce any such visually obvious disruption to the skin, although there might be some redness or swelling.

For active inflamed Acne, if any laser is used it would be non-ablative. However, if Acne scars are being treated, both ablative and non-ablative lasers might be utilized.

Ablative lasers are ones that actually destroy skin tissue during the treatment, while non-ablative lasers do not destroy tissue. When an ablative laser is used there is normally a fair amount of "downtime" because the injury caused to the skin tissue during treatment is enough so that a recovery period is required. Non-ablative laser treatments typically allow you to get right back to work, home, school or other activity with no recovery time. Think about it in terms of an injury caused to the skin by the lasers. The healing process associated with this controlled injury causes the skin to improve and ablative lasers cause more of an injury than non-ablative lasers.
