Your concerns are well founded, and your questions are entirely acceptable. There is a lot of concern from first time patients about the safety of fillers around the mouth. I will try my best to explain everything to you. The wrinkles and lines you see around your mouth are probably the most unnerving signs of aging even more so than the signs of aging in the upper face such as forehead lines etc. This is because they probably reveal the most about your age. When we are young the lips are pouty, tight and full of youthful collagen but as we age we begin to lose some of that volume so the lips start to thin out and lines start to form around them. The muscle called the orbicularis oris helps us purse our lips, think of drinking out of a straw, this also in turn affects the appearance of the lines and makes them more pronounced. Sun damage, dehydration and smoking also worsen the outlook. When you consider rejuvenating that area you are essentially aiming to correct the loss of volumes (using soft tissue fillers which are essentially procollagen forming agents that love water and draw water in to help restore the volume and fill) as well as using botolinum toxin to paralyze the muscle around the mouth that is constantly pursing and creating these deep lines (known as barcode lines, smokers lines) In the past, surgeons would recommend extensive facial surgery to help rejuvenate the face. Pulling and cutting on tissues to help restore that young, tight facial appearance. This has now changed, in fact, even in patients we do elect to treat surgically, we still recommend fillers to help augment or improve the appearance of the face (sometimes there is no other way to replace lost facial volume other an a filler). Fillers will add volume to the spaces in between the lines, improving the appearance of your mouth. Most patients are overly satisfied with injectables. You do not have to have fillers injected, you can chose to see a specialist who may recommend laser treatment or even topical creams such as retinols or vitamin A derivatives. Hope this helps.
