I'm just starting my 3rd month of using this amazing serum. I am 65, and my neck looked it! But no more! I've been using Rebecca's protocol of Rosehip Seed Oil on my face and neck, covering with a warm cloth, wiping away any dirt or impurities and then using the serum. I am blown away by the results! My skin is soft and supple, my neck looks easily 10 years younger, and there are diminishing fine lines as well. The combination of Rosehip Seed oil and Ultimate Skin Serum truly makes a wonderful difference in the condition of your skin.
