Is there any possible way to change face shape without surgery . i mean my face big so can i thin my face .. and nose also

Thank you for your question.  There are numerous non-invasive methods of adjusting facial appearance including the use of Botox and dermal fillers.  See a board certified plastic surgeon in consultation to discuss your treatment options.  Best wishes. 

It would helpful to see a photo to make recommendations, but you can generally use a combination of volumizers (dermal fillers), neuromodulators (eg Botox, Dysport), or the use of energy devices such as Ulthera to shape and soften the signs of aging.
