Since I have severe wedge-shaped pores around my cheeks, I went to a large dermatologist in my neighborhood and received the treatment three times over four and a half months. In conclusion, it was effective. I can see very, very, very subtle fillings hahaha. People around me also say it looks a little better than before, but the problem is that my pores fill up and close, so they change from deep wedge-shaped pores to wide pores hahaha. So, when I put on makeup . In fact, the pores seem larger than before. But that's because I stopped the treatment midway. If I really maintain it for a long time, I think it will improve little by little. Or, if you have round-shaped pores, it may be effective. And my skin tone actually got better than my pores. I feel a little brighter haha. I didn't have high expectations, so I'm just satisfied, but I think it's a procedure that will be very disappointing for those who have high expectations.
