I have no idea why this serum is not available at Sephora, Bloomingdales, Ulta, etc it would sell out like crazy nationwide. It goes on very smoothly. Love the light fragrance. It is not too thin and it is not too thick so your skin absorbs it easily. It quickly reduces hyperpigmentation/dark spots/scars. With just a few applications I saw real results. Plus it improves skin texture and shrinks large pores. I cannot recommend this serum enough. And this is coming from someone who has tried many dark spot removers. I was hesitant to pay $100 for this but if I had known this is the result this serum would deliver I would have gladly paid the hundred dollars. It is worth every penny. Please do not discontinue. I love, love, love this serum!
