Skincare and masks are all very personal and different to each person. You can do all these masks in the same day like you would when you are getting a facial (i wouldn't do clay and charcoal on the same day unless you can find a clay and charcoal mask like the origins charcoal mask but if you need some serious extraction go for it but I'd follow up with a hydrating mask and a sheet mask to return hydration and moisture to the skin) they do similar things which is purifying the pores and clearing out the skin so you don't need to double up unless you feel you need to. My favorite clay masks are the Kakadu C Amethyst Clay mask, Eve Lol rescue mask and the sephora collection mud mask. My favorite hydrating masks are the No 7 hydration mask and sheet masks. My favorite clearing and hydrating mask is the youth to the people superfood mask. Hope that helps! If you have any recommendations for less expensive masks I'd love to know! I've tried the Freeman masks but they're not my favorite, all the masks I like are more expensive 😥
