I use to work for Estee Lauder and I can tell you that anyone can get those lines. The reason people associate them with smoking is because they get them more than anyone else. All you have to do to get those lines is do a repeatative movement like you would if you put a cigarette in your mouth.
For instance, whistling and drinking out of straws make your lips move in that same form. I would try a cheaper and less invasive form of treatment before going to the extreme of injections.
First find out what it is that you are doing that to make that particular shape with your mouth and either elimate that habit or try to change the shape of your mouth when you do it.
The next thing I would recommend is Estee Lauder Perfectionist Correcting Concentrate for Lip Lines. Its only $35.00/ This is a thick serum/creme that you put around the outside of your lips (where those lovely lines are) morning and night. It does have the benefit of keeping your lip products from bleeding, but its purpose is to soften the look of those lines. Note: if you do decide to buy this you will have to get the tube started by turning it about 15-20 clockwise turns before the product is up to the top and ready for use. You can ask the EL consultant to help you with that if you don't want to do it yourself.
Please not this is a treatment product not a cosmetic product. So over usinging won't help you. Use as recommended and you will get results.
