Your procedure area may be slightly swollen and irritated. This is called a "wheal and flare" reaction. The area may also be darker for a few days while it is healing because of the lymph and blood droplets that may have been brought to the surface during your application. While your procedure area is healing, it must go through three phases before you will experience your final results. The procedure area must first heal, peel and fade. Final results may take 6-8 weeks to completely heal.
