I'm one of those "I don't write reviews" people -- I typically don't. But I'm also obsessed with my skin, and now with this product! I've been using it for about 10 days, morning and night. Great texture and almost inperceptible fragrance (which I like). In the AM, it goes under my moistuizer/SPF. At night, I've been using it over a retinol product, then followed by a moisturizer. It's definitely boosted the results from my existing routine. The redness and drying that I typically get when I use a retinol has virtually disappeared. Which also means I can use the retinol more nights of the week (a bonus in my book!). Also, I noticed that since incorporating the milk serum, the fine lines around my eyes are less visible, and it's "plumped" out my pores for a smoother look. Another thing... we're entering winter here, the heat is on at home, and usually this is when I start to see my skin shrivel up, despite slathers of moisturizer. Since I've been using the Milk Serum, my skin feels and stays hydrated. It will remain a staple in my routine!
