How Much Down Time is Needed After Erbium Treatment?

Depending on how aggressive the treatment, usually 5-7 days is enough time to heal. Thank you for your question and good luck.

It depends, even when you mention medium as a depth. My erbium laser is by Scition (www.sciton.com for more information that might help), and allows three different ways to apply erbium energy. A micropeel means you treat all the skin about 20-60 microns deep. Takes 2-5 days for the skin to heal, redness then disperses usually within another week.
Erbium can also be fractionated, called profractional xc. That treats 11% or more of the skin with vertical microchannels that are deeper than the microlaser. We average about 300 microns with most patients. That will also take about 4 days to heal, redness another 4. But we are still able to provide that in a clinic setting and minimal anesthesia (ie topical).
Conventional erbium laser may be what was described to you. Now we treat 100% of the skin surface again, but are back to the 250-500 micron depth. That takes about 7 days to heal, but the redness persists for another 1-6 weeks. It also requires at least IV anesthesia.
More aggressive treatments take longer to heal. But they offer more results. Microlaser and profractional treatments are best designed for more than one treatment, while the erbium is just once.

The erbium laser is fully ablative and the downtime is similar to that of an ablative CO2 laser, aggressive chemical peel (35% TCA or phenol peel), and dermabrasion. The entire surface of the skin is removed to a variable debth (50 microns for a "mini-peel or 300 microns for an aggressive treatment). The skin will generally regenerate (re-epithelialize) in about 10 days making this the earliest time you could get back into cover-up make-up. We recommend a mineral make-up such as GLO mineral make-up. The skin will be very red for about a month after and then less red for about 3 - 4 months.
It is very important to avoid sun exposure during this period because of the risk of a condition called postinflammatory hyperpigmentation (PIH). Judicious use of sunblocking agents is necessary and oftentime it is easier to have your treatment in the winter months. Very moist skin care is generally recommended in the first few weeks after treatment.
Fractionated laser resurfacing (Fraxel) can give similar results to the Erbium but with significantly less downtime.

The downtime depends on the aggressiveness of the treatment.  It may take 7 to 10 days for healing to occur.  Follow your physician's after-care protocol.  Avoid the sun and use makeup until the pinkness fades.

The amount of downtime after an Erbium laser treatment depends on which Erbium laser is used and the laser parameters chosen by your physician.
The downtime can vary anywhere from absolutely no downtime when an Erbium micropeel is used to between 7 and10 days from social activities and work with a more aggressive approach.
