If you want one product to solve a broad range of skin problems, this is about as good as it gets. Almost an exact dupe for the Estee Lauder Advanced Night Repair, I actually prefer it to the Estee Lauder, especially the updated Borabit version. This ampoule brightens, fades dark marks, provides anti-aging, repairs sun damage, and improves the health of skin. It's alcohol-free and has no huge irritants, making it ideal for most skin types. The Borabit version improves the previous version by decreasing stickiness and having a lighter formula. The dropper-type bottle is hygienic and convenient. One bottle lasts me about four months of once per day use. My skin feels brighter, bouncier, and more even. My mother also uses this product and has found it fades fine lines. A good product for all skin types.
