is it possible to obtain Adriana Lima's lips without looking fake?

The results of your lip augmentation depend on how your original lips are. Lip augmentation is designed to make your lips look better, rather than make your lips look like someone else's. Making your lips look like someone' else's will achieve a fake look, simply because they will look out of place on your face. The key to improvement is to achieve better proportions. Best of luck!

Adriana Lima does have beautiful lips. Without a before photo of you it is hard to say whether or not you will be able to achieve a similar look. Schedule a consultation with a plastic surgeon and let the doctor assess your lips. Products such as Juvederm, Belotero, Restylane and Revanesse are all great for lip augmentation. Always be sure you are seeing a board certified plastic surgeon. Best of Luck!  

So the way I would look at this is: you are you and probably have many beautiful features, why would you want to look like someone else?  You can definitely enhance your lips to bring out a little more of your natural beauty, but if you try to replicate someone else's features, I think you are setting yourself up for disappointment and possibly a fake-looking result. There are many different types of lips, and while you can always plump lips, one cannot always change the basic shape and features by adding filler.
