The exfoliating effect is powerful enough to deeply refine the skin, and gentle enough to ensure a comfortable, non-irritating treatment with beautiful results.Renewal Complex 1, formulated with a gentle 5% dose of glycolic acid, is a light to medium exfoliation treatment, recommended for sensitive to normal skin types. Achieve full area exfoliation for clean, fresh and bright looking skin. Also recommended for specific areas of hyperpigmentation and sun or age spots, acne-prone or oily skin types. Follow with Jet Detox Water treatment to remove residual glycolic acid. Avoid sun exposure and use sunscreen for 24 hours following treatment.
