Brows like Ariana Grande - which procedure should I get?

If you are in your early 20's, and depending upon racial background, face structure, etc, surgery would be inadvisable. The arch and curve of the brows are achieved by people in your age-group using several techniques: judicious brow shaping/plucking, tight hair styles!!!, raising brows when being photographed (afraid that is what happens with may of the "stars"), and botox. You can explore all of the above. Just not surgery at your age!!Good luck.Bhupendra C. K. Patel MD, FRCs

It's hard to give you advice without seeing your photos.  There are different ways to raise the eyebrows.  Botox will work for a temporary lift.  Browlifts are another option, but you would need to be evaluated since you are in your early 20's.
