Truly refines skin tone & speeds up healing. I have oily, acne prone skin and this helps mattify without drying out my skin. I hate paying for it but I am on my second bottle and I am pleased with results. I use with retin-a micro & infrared light therapy. I thnk it is worth it.
I've used their moisturizing cream for years. It's been the best product on the market for my skin and I've tried many others. Now that I'm past menopause, I find this additional serum to be a real enhancement (when no other additional creams really were). It also extends the life of their moisturizing cream as I need less so that pricey item does last longer. The downside, as others have noted, is the poor packaging. Does marketing not realize that their credibility as "scientists creating great products" is somewhat suspect when they don't get the container right?
