My twin sister and I are OBSESSED with this product! Thank you Dr. Alex (CEO of Blonde Girl Aesthetics) for introducing Colorescience / The Barrier Pro spray into our lives. Whether you are at the barn all morning working the thoroughbreds for their race day or working in pharmaceuticals- this pick me up makes me feel like I just sat in the sun with my eyes closes for 5 minutes. It truly awakens you! I have travel size and large size. I use this every time after I wash my face- then after it dries I apply my other serums. I do not spend much time in the sun so the D3 in here makes me feel completely nourished!

Finally, a serum product that doesn't have Niacinamide in it!! I'm allergic to Niacinamide but everyone puts it in their products these days, so I was relieved to see this didn't have it. I already love this company's sunscreen, so I decided to give this serum a try. I use it nightly to layer under my Retinol and moisturizers, and after three months of using it, I can say it's definitely made difference. I may try to use it alone without my other products to see how big of a difference it makes, and I thought maybe I would go without it once I finished the bottle to see if it was just my other products making a difference, but I found myself compelled to order another bottle. I think if you have sensitive skin and need something to sandwich between your Retinol, this is a great product!
