Face Sagging After Subcision

Hello everyone,

I had subcision done twice in the US about 4 years ago when I was living there, mainly to treat my acne scars. At the time, I didn't think much about my overall face shape. Recently, I reconnected with some relatives I haven't seen in a while, and they pointed out that my face shape has changed - it looks droopier and more oval now. I hadn't noticed it until recently, since I don't often take selfies, but looking at photos from my driver's license from back then compared to now, the difference is definitely noticeable. I'm starting to wonder if this could be a side effect from the subcision.

I'm a male in my mid 20s so I'm not considering any major plastic surgery, but I'd like to address this issue. Currently, I'm in South Korea, where cosmetic procedures are advanced and relatively affordable, so I'm looking into potential solutions. Just wanted to share my experience in case anyone else has gone through something similar.
