This product was recommended to me by a person who worked at Kiehl's, who really helped me with the peeling and scars that I developed from very intense sun damage on my face. I used it, and I was amazed that the results. It was a long-term process to get my skin healthy again, and I still use it to this day (after years of use and serious trust in the product). This is definitely a long-term product, but if you use it correctly (I use one droplet of product on my wrist which I pick up with my other finger to spread around my face, and that's all you should need, also) it should not run out very quickly. I've replace my bottle once a year, maybe longer, so I believe it's a fantastic investment for the long-term health of your skin. This product can be used for many different conditions, but I suggest really understanding your condition and how to help it before making the investment. Other things I use it for: dry acne spots, peeling skin, thin skin. This product has honestly saved my skin and I will use it forever.
