Pixel laser can stimulate collagen growth, which may thicken
the skin and decreases the signs of wrinkles. However the amount of
growth is different among patients and it may take several treatments to notice
any significant change.
I would avoid wearing makeup until the skin has peeled off
and the new youthful skin has begun emerged, usually about one
week. During the healing phase, it is important to apply moisturizer
constantly to prevent the treated area from drying out.
For facial scars, I would use a combination of fractional laser, EMatrix, fillers, and microneedling. In some cases, fillers may help with atrophic scars. Best, Dr. Karamanoukian Los Angeles
