My new favorite product! I used the collagen with a 4 mm 30 g meso tip ! I was careful to take the correct steps. The bumps lasted longer than any other products on me however !! It was so with it ! My skin hasn’t looked this healthy and radiant in 10+ years . I look forward continuing my journey with Tesoro collagen ! Thank you to Jessica without her this would not be possible Jessica10 will always save you the most at acecosm !
