Thank you for your question. Lip fillers come in several varieties. Basically, they are divided into permanent fillers and temporary fillers. Permanent fillers, namely, silicone injection is something that I DO NOT DO in my practice, and it is exactly because of that fact that I do not. I avoid all permanent fillers in the face since if the patient does not like it nothing much can be done, and that is a horrible situation. Temporary fillers are divided into hyaluronic acid (Juvederm, Restylane, Voluma, and others) and hydroxylapatite (Radiesse). The former is more smooth and pliable, and consequently is used much more often than the latter, which is more viscous and tough and used primarily for cheek augmentation. Additionally, your own fatty tissue can be used as well, but that involves harvesting and processing the fat. From the picture you sent it looks like your lips are fairly full and voluminous, and I would caution in enhancing them. If you do decide to go with a filler lip augmentation procedure, I urge you to consult with a Board-certified plastic surgeon to get a bonafide clinical assessment. Hope this helps. Good luck and farewell.
