I got 2 ml of lip fillers in one session 8 months ago, & want to get my lips done now, can I get 2 ml in one session also?

Thank you for sharing your question. 2ml of fillers is a lot for injection of fillers into the lips in one session. You probably would do best injecting 1ml at a time to ensure a pleasing result. See an expert injector for best results.Good luck, 

This is difficult to answer without pictures. It may be possible to get another 2 ml depending on your desired results. Lip augmentations with fillers is a great option to improve the fullness, suppleness and symmetry of the lips. Results can be very natural-looking and will feel very natural. 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 and go over the cost of your procedure. 
I hope this helps.
