Your own tissue can be used to improve changes in your appearance from trauma, acne, or the effects of aging. For small areas, like acne scars or your 'lipstick line,' laser dermal grafts are used to help restore natural proportions. Larger areas, like drooping cheeks, are improved using fat grafts. In the past, fat grafts were typically temporary. Using improved techniques, permanent results are more common. For the best long-term results, more than one treatment session may be necessary. While initial recovery can be as short as several days, you should allow seven to 10 days for swelling and bruising to heal.
