Is Ultherapy a good option for a 21 year old? I would like to have a tighter jawline and more defined cheekbones.

Yes, Ultherapy can potentially be a good fit or you. Ultimately, a consultation is required to help you make that determination. 

We start losing collagen by the time we are in our mid-20s, so 21 is not too young to begin thinking about tightening and improving the quality of your skin with Ultherapy. Ultherapy uses ultrasound energy to heat up the collagen, forcing it to contract and produce newer, stronger strands of this important protein. The skin tightening may be exactly what you need to give you a tighter jawline.Other collagen-promoting skin-tightening treatments that work as well as Ulthera are Thermage and Thermi RF. However, if you really want a more contoured look, building up your cheekbones with Sculptra or HA fillers like Voluma, Restylane or a combination of the two may be the way to go. The extra volume also adds a lifting effect that can make your jawline look sharper. Please consult a board-certified dermatologist who is an expert at creating beautiful, healthy faces with Ultherapy and fillers.

Thank you for your question.  I do not feel that micro-focused ultrasound is likely to produce the aesthetic changes you're hoping to achieve.  In my experience patients and your age demographic with your goals benefit more from injectables then from Ultherapy.  I recommend sending a physician who is highly experienced in facial rejuvenation.  Best of luck.

Ultherapy is great to preventatively tighten skin, i tell everyone to do it once a year.  However, if you want more definition or shaping, there are options.
1) implants
2) fat or filler injections
3) ThermiRF, Thermage, or J Plasma on the neck/jawline
4) PDO Novathreads or instalift threads for lifting
5) Neck or facelifting surgeryI suggest you see an expert.  Best, Dr. Emer.

Whether Ultherapy is appropriate for you can only be determine through an in-person consultation and examination. In general, Ultherapy works well as a preventative measure in younger individuals. Though results may be subtle externally, it works internally to build collagen and slow the aging process. Make sure you see an experienced physician provider. Best wishes.

As you can tell, we are BIG Ultherapy fans in my Del Mar, CA practice. 
Ultherapy is a good skin tightening and lifting procedure. It works at any age, but the younger the patient is the more collagen can be stimulated. Used at the correct settings by an experienced practitioner there should not be fat loss. 

Thank you for your question. Ultherapy is a great preventative for young adults and will not speed up the aging process. I do recommend that you work with a facial plastic surgeon's office to have Ultherapy done as they will be able to best recommend any other treatments that may help you achieve your ideal results. Also, the anatomy of your face will change through the decades, making it imperative that you have a guide and personalized plan to maintaining your ideal appearance.Good luck!

Ultherapy uses ultrasound energy to tighten muscles and skin.  It is a wonderful treatment for anyone wanting more definition in the face or neck.  You are a wonderful candidate, because it is easy to stimulate tightening in young adults.  You are not speeding up the aging process.  In fact, you are putting collagen into your "collagen bank", which slows down the aging process. Best of luck to you.

While there is no age restriction to using Ultherapy, this would have to be evaluated on an individual basis.  Ultherapy should not affect any body fat changes in the future as it's primary purpose is to help tighten loosening subcutaneous tissues.  When done regularly, it could possibly avoid the need for a facelift in the future.  There definitely should not be any concerns about speeding up the aging process with Ultherapy.  Best wishes.
