Lasers can be separated into two categories, ablative and non-ablative. The Fraxel Dual is a non-ablative laser on either wavelength. This means that it heats up the underlying skin tissue and does not harm the surface, resulting in collagen stimulation and production and improvement of the overall texture. An ablative laser actually removes the top layer of skin, which is why recovery from an ablative laser treatment takes much longer and is more involved.
What does “non-ablative” laser mean?
