Good day, I am 56 years old. I had radiation therapy on my neck for tonsil cancer. Now, the skin is sagging on the lower part of my face, also due to the weight loss (I have lost about 17 pounds (ca. 8 kg)), and there are more wrinkles on my chin. I would like to have fillers done. Would it be ok? Also, will the face return to normal, once I get the weight back? Thank you.
