My cheeks are really sunken in; are the benefits of fillers really undeniable? lol

I followed a pretty strict diet for two months, and while my body got thinner, I ended up losing all the weight in my face instead. ㅠㅠ The nasolabial folds next to my nose and the front of my cheeks are deeply sunken, and everyone around me keeps asking why I look so tired and sick, which is really stressing me out. lol I want to instantly fill in just the sunken areas naturally, but I don't know... filler I'm planning to go to a dermatologist because I think a procedure would be the fastest and most effective way! But I'm really worried about feeling a foreign body sensation when I smile or about it sagging down later. Domestic vs. imported products filler Each has distinct differences. merit I'm so curious if this is possible. My skin is on the thinner side, so I'm wondering how many days the bruising or swelling lasts, especially for faces with severe sunken cheeks like mine. filler If any of you have tried this, please leave me a genuine testimonial confirming if it really helps return to a youthful, vibrant face. ㅠㅠ
