Thank you for your question. Alastin Regenerating Skin Nectar prepares the skin for a rejuvenation procedure, such as Fractional Laser or Ultherapy. The Alastin Nectar proprietary formulation helps clear the damaged collagen and elastin fragments from the skin due to aging and sun exposure. The Alastin Nectar also stimulates new collagen and elastin production. By clearing the damaged collagen and elastin cells and promoting new cell growth, the skin becomes fully functional with improved cell to cell communication. When the collagen and elastin cells can better communicate prior to a skin rejuvenation procedure, the results of the procedure are accelerated and improved. After the procedure, the Alastin Nectar also contains ingredients to accelerate healing for less downtime. We recommend that you use Alastin Regenerating Skin Nectar two weeks before and after a skin rejuvenation procedure.
