So i have a bottle of LG 4AD td, only problem is it's kinda clumpy. When applying it there are little dried glue looking stuff that flakes off after it dries on the skin. I tried heating it and used a whisk to blend it back together but it's still a bit clumpy. Any ideas on how to get this back to it's regular consistency? I can use it as is but I don't want to waste any of the 4AD in it. Thanks!
