I ordered the Tesoro collagen during the one day sale. I used two vials on my face, and 1 on my neck. The small blebs were almost gone by the next morning, and my skin is radiant and glowing! The collagen gave my cheeks a little boost where I feel deflated, and I am so happy!! I am ordering more today, and this will be a staple in my skincare routine. Thank you Acecosm for such a great product!
