Chemical peel: Is when a certain chemical like alpha hydroxy acid is lathered at the right amount on your face and is left there for about 10 minutes before it’s washed off. This will help blot out the top layers of your skin, which helps lighten the scars on your face. This process is especially used for acne scars, but can also be used for deeper scars. You can do this once a month. Microdermabrasion: is a more manual way of removing the top layer of your skin (the epidermis) through a microdermabrasion device- which comes with a diamond tip that slowly exfoliates the outer layer until the new and more vigorous skin surfaces. You can do this every 2 to 4 weeks. Photofacial: Photofacial uses a beam of light and targets the pigments or the scars.
So not only does the outer layer start peeling off, but the lower layer is also heated which then causes more collagen production. And more collagen production means healthier and younger looking skin. You can do this once a month.
