The retinol serums from @ColleenRothschild are two of my favorite products. Made with the highest concentration of retinol, vitamin C and 9 plant-based oils they’re my go-tos for nightly hydration. Right now if you spend $100 you can get $25 off your order with the code HOT25 http://liketk.it/3mFA6 #liketkit @liketoknow.it #ColleenRothschild #CRbeauties #sponsored
