The Perfect Peel Plus booster contains the same synergistic blend of ingredients as The Perfect Peel, but at a higher concentration, and boosts the effects of The Perfect Peel. The Perfect Peel Plus booster is an excellent addition for treating stubborn Hyperpigmentation and Melasma, thick resilient skin, Actinic Keratosis, and age spots on hands, arms and chest. The Perfect Plus booster is to be used in conjunction with The Perfect Peel. Rupesh at his Harley Street Clinic in London will discuss this with you at your appointment. For some people with sensitive skins, boosters may not be appropriate in the first treatment.
