Like many things in life, your return or results are directly proportional to your investment, or in this case downtime. More aggressive treatments will give you better results, but they will also come with more downtime.That being said, you need to define what downtime means to you. The feeling of warmth, weeping, and peeling are usually done within a week with even the more aggressive settings, and it can decrease proportionally from there with less aggressive treatments.Redness can persist well beyond the original week of downtime, and although persistent erythema has been considered a "complication" of ablative lasers like the CO2, it can easily be covered with make up or even just a lightly tinted sunscreen, which you should be wearing afterwards anyway.Of note, the new fractionated technologies allow more aggressive settings with a decreased downtime than you would otherwise have to endure to achieve similar results. Fractionation simply means that the laser treats small micro thermal zones covering varying densities depending on how your physician sets it instead of ablating the entire top surface of your skin. With just these micro thermal zones being ablated, the normal islands of skin in between allow a more rapid healing.To discuss your needs and likely downtime, seek out a dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these "core four" cosmetic specialties.
