How does a WiQo Peel work? January 24, 2023 Your WiQo® Peel treatment will begin with a deep, delicate cleansing of the treatment area. Dr. Downey or Dr. Bullocks will then apply the WiQo® Peel serum solution, massaging it into the skin. Once the determined number of layers has been applied, the serum residue is washed from your skin. A post-application cream may be used to help ease any slight burning or itching sensations.
