Vacuum crystal micro dermabrasion has been used in skin clinics for over 20 years to remove the topmost layer of dead skin and to encourage skin rejuvenation. Rio Crystal Renew uses this same technology to help reduce the appearance of fine lines and wrinkles, to improve skin texture and tone, and to give a more youthful and radiant appearance to the skin. Vacuum crystal micro dermbrasion is also ideal for evening skin tone, improving sun damaged skin, reducing enlarged pores, oily skin and acne. Just like in the salon, fine crystals are blown against the skin surface and removed with the dead skin by a vacuum action. Mains operated. Manufacturer's 2 year guarantee.
