I heard it's hot in-mode, so I've tried it twice at a nearby place, but after the first time, the effect was definitely felt. In fact, it's a complete double chin person... Anyway, it's in-mode and definitely improves the face shape. It's better than not doing it... But I put 600,000 won in 2 episodes now, but usually 3 times, if I add 30 more, it's 90... I wonder if this is the salary for a first-time social worker.... 300,000 won in 30 minutes.... I love that the manager is very thorough and makes you feel comfortable! But maybe it's a problem with my face shape...I think I've hit a limit...I'll think about it more for the 3rd time!!
