PROBLEM SOLVER: WRINKLES, LOSS OF ELASTICITY. STIMULATES COLLAGEN REGROWTH & FIRMS SKIN Welcome! We are pleased to announce that we have added a few new products to our store, this Powerhouse Collagen Building Serum is just one of them! Compare these ingredients to those used in products such as Elmis and Pevonia. This product is very potent for building collagen – thickening skin and firming. Great for under the eyes to reduce that hollow look, and masking the appearance of dark circles that are hemoglobin-derived. I recommend this for the entire face and neck also, if you have any areas you would like to firm up.
