Will 0.5ml lip filler be enough to plump my lips and my smokers lines? (Photo)

Generally, I start with 1 ml lip filler  to add volume and shape to lips. Leftover product can then be used to fill in lip lines. Consulting with a board-certified dermatologist will give you a better idea of the results you can expect.

Thank you for your question and picture.  I would recommend 1 ml, 0.5 ml will make hardly any difference.  I would suggest filling the lips first and maybe using a resurfacing method for the smoker lines such as laser or chemical peel.  All The Best 

This will create very subtle improvement. I recommend starting with 1 ml. I prefer to use a micro cannula to inject the lips to prevent bruising. Look for a cosmetic dermatologist or plastic surgeon who is an expert in fillers to discuss your desired results and concerns. 
I hope this helps.
