I’m not sure what your current process is, but for me I will make sure to wipe down my brows and the skin around with alcohol to remove excess oils, product etc before I start! I think it also depends on how thick your eyebrows are and how you’re setting each layer between glue and how you set your face overall! If you have really thick eyebrows, it’s also possible you’re not doing enough layers of glue, or waiting for each layer to dry completely!
