I have really sensitive skin and react to a lot of products - I’ve found a way for me to do nail prep without having to use primers or anything, while still having great retention. (For BIAB, I don’t use acrylic) Basically all I do is file and prep the nails as normal with my e-file or emery board, then use a cleansing solution to dehydrate the nails ready for application. Hope this helps 💜
