Should I stick with the same lip filler consistency each time?

Hi and thank you very much for your question. No, you do not have to stick with the same type of filler while building your lips. Certain fillers are better for creating a nice sharp border and definition, while others are better for volume, etc. Each patient is different as each patient has unique anatomy therefore treatment should be individualized. If you are happy with the results from your previous filler than there is no problem staying with that. I hope this helped! Best wishes.

Thank you for sharing your excellent question.  Assuming you have not had any issues with your fillers, there is no need to maintain the same type each time you have an augmentation performed.  Better to stick with whatever filler helps you best achieve your goals each time, however. 

Dear AGC34
I typically use Juvederm for my lip sculpting. There are two main focuses of lip injections, adding volume and actually sculpting the shape. Both involve injecting the filler in different areas of the lips and patterns.
I would recommend finding a plastic surgeon to perform you lip injections. Most of my patients have results that last at least 6 months.
