Depending on the concern you are treating the side effects of the treatment can vary. For pigment or pigmented lesions, typical after-effects of the treatment consist of, slight redness, immediate darkening of the pigment (this is what we want to see) followed by crusting or flaking of the pigment over the next 5-7 days. This is your body naturally removing the pigment and your pigment will be visibly lighter and or removed completely.
For vascular imperfections, blushing and rosacea treatments, you can expect redness, some mild swelling or puffiness, and darkening of the blood vessels, over the next 2-4 weeks your body will naturally re-absorb these treated vessels and they will disappear.
