I have read that patients with a round or fuller face do not get a good result from Ultherapy. Is this always that case?

ultherapy doesnt depend on facial shape. but your goal is what does matter I suggest a consultation. ultherapy is for prevention I dont think ulterhapy gives much result it just slows the process down. I do it twice yearly for myself with thermage for "preventative" sagging.

at home peels like cosmelan, enlighten and aerify along with dermarolling (MTS roller with anteage MD ampules weekly, see linkt) should be started now to prevent further aging.

For facial rejuvenation, I would suggest a combination approach of
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel/halo Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8 for tightening of the skin
8) Vascular laser like vbeam/excel V or BBL forever young treatment every quarter (3-4 months)

Hello and thank you for your question. Ultherapy works on all kinds of face shapes and sizes. I dont see a picture enclosed which would help but I suggest an in person evaluation to discuss your concerns and options. Best wishes.

Ultherapy is ideal for all skin types and different shape of faces. The nice thing is that your provider can customize the treatment by using appropriate transducers to give you good results. Thinner face or fuller face individuals with no contraindications can safely have the treatment and still get good results.
