Facelift for Young Adult (Age 21), Too Young?

If you want to improve your contours, you may want to consider fillers. Injectable fillers can help add volume where you find is deficient. However, if the jawline is your concern, you may want to consider Botox to relax the masseter muscles.

The need of a facelift at your age is very unlikely, but photos are needed to asses. If lower facial fullness is your biggest concern, strongly consider some face/neck liposuction to sculpt these areas. 

Photos please!

Thank you for your question. See a reputable Board Certified Plastic Surgeon, and have an evaluation, and they will let you know if your concerns are realistic, and whether or not there is a good list of alternatives for you to explore. I hope this helps.
