Originally, I was a person with a lot of hair on my body, and I was a person with a thick beard. That's why, even after shaving, there were bluish marks + I had to shave, so I had a skin problem . I received it over 20 times at intervals of 1 month and then at intervals of 2 months . It seems to have disappeared immediately after receiving it until the first 5 times, but I thought it was going to come back up . It seems like I 've filled it up 20 times, but the pharynx is almost nonexistent and only the chin is tingling.
