Best serum ever. Period.
My go-to serum. I have tried other hyaluronic acid serums but THIS ONE is the absolute best for me. Others make some sort of web on my skin that peels after, or are too sticky. This one is perfect. I can't live without it. I have a very VERY sensitive skin, with eczema and many allergies, and this Rainfall serum is life saving. Thank you Colourpop for selling this very hydrating serum !
