I love this serum it has no scent and it absorbs very beautifully. I wear it under my moisturizer during the day, but I've found that if I use this at night my skin looks better when I wake up. And I was seriously unaware that Cetaphil made serum products! Excellent pricing, excellent texture, and excellent contents. It contains vitamin c, niacinamide and hyaluronic acid all in one. Without a doubt, I would purchase this product for myself and recommend it! It was such a positive experience! One huge advantage for those who are allergic to scented skincare is that there was absolutely no scent in this serum. I will absolutely try other products of the same line.
