Hello Interloper!

Fractional photothermolysis or laser skin resurfacing offers speedy healing and minimal to no downtime.
Depending on the area of your body treated and the type of device used, the procedure is said to be well tolerated; feeling like a mild prickling or burning sensation, or like elastic bands flicking on the skin. However, your practitioner may apply a topical anaesthetic to your skin prior to treatment to reduce any pain and discomfort, and offer you a chilled air device to hold over the treatment area yourself.
For several hours afterwards the skin will feel tight and have the appearance of a “sunburned” look. The skin will continue to look “pinkish” for 2 - 7 days (depending on the device used) and any swelling, which should be minimal, usually disappears after 1 – 3 days.
With Fraxel™, a bronzed, sun tan look caused by the dead, burnt cells at each MTZ will then remain for 3 – 14 days before naturally exfoliating.
Generally, as the skin heals itself, you will find mild to moderate skin flaking, which may last for up to 2 weeks.
Side effects or risks are minimal with this type of treatment and typically involve swelling and redness. There is a very limited risk of infection or scarring, with no oozing or crusting of the skin having occurred according to the manufacturers.
Compared to laser resurfacing, there appears to be a reduced risk of hyper- or hypo- pigmentation (areas of darker or lighter skin colour) with fractional photothermolysis. This is thought to be due to the fact that areas of healthy tissue are kept intact between the treated areas, unlike with ablative lasers, meaning that lasting pigment change does not occur.
If the practitioner uses the laser at higher powers, there is a risk of mild blistering (mainly on the chin and temple areas) and/or temporary skin discoloration, especially in darker-skinned patients.
