I wipe my eyebrows, eyelashes and lips with vitamin E mixed with olive oil every day, and I never get fat particles. The drawing is very simple. You can rub your fingers directly where you want to grow eyebrows, or you can use a small tool like a cotton swab. Personally, I still think it's not so wasteful to use my fingers. It is best to wipe it before going to bed, because it can help the eyebrows to absorb well at night. Usually just put it on after washing your face. My eyebrows are so black that I don't need to draw them at all. Eyelashes are also longer than the average person.
Wei E uses Hainan Yangshengtang's best. I used to buy it at a drugstore, but now I buy it at Dangdang. It's cheaper than a drugstore and it's genuine.
In addition to the above methods, some people use ginger to rub it.
Eating more black food, such as black sesame seeds and black beans, helps to make your hair thick.
