I got it around 2023 because my chin acne was so severe! I received it at event prices at three clinics (Seoulmi, Heyday, Abijou), and among them, Seoulmi Clinic seemed to do it the most sincerely!
Since this targets the sebaceous glands, I don’t think I got chin acne after receiving it? The sensation was just warm, not painful at all lol If anyone is worried about acne, I recommend trying it once
