Numbuzin and Retinol together?
Hi everyone! I’m currently using a retinol product in my night time routine. Does anyone know if we can combine these 2 products together?
I read that it has Bifida ferment and Galactomyces Ferment. Hence would like to try it out but I don’t know if I can combine them in one routine? :(
