There are quite a few products on the market now and the trick is picking the right one. I would steer away from anything permanent. There is more risk of infection as the needle has to be thicker, and also if you are not happy with the results there is little you can do to change it.
Restylane is one of the most common fillers. It comes in the form of Restylane, Perlane ( used mainly in lips as it is thicker- slightly more expensive too) and Sub Q. They are all of different thickness to fill particular parts of the face - so what you fill your lips with is not always the same thickness as the product you fill your fine lines with. This is made of hylauronic acid, a substance that is naturally occurring in our bodies. It helps to absorb and bind to water to provide hydration and this depletes as we age. So it simply replaces your body's diminished levels of this hydrating substance.
Restylane is long lasting but not permanent. It has been shown to last up to 36 mths, depending on your metabolism, but personally I think this is in rare cases. The most I have seen it last is around 9mths - 12 mths.
Esthelis is made from hyaluronic acid too. It is biodegradable and biocompatible so there is no risk of allergies and the likelihood of side effects is greatly reduced. Used to treat moderate to deep wrinkles , scars, increasing the volume of cheeks and chins, lip enhancement. Results last between 9-12 mths.
There are 3 different products within the range....
Esthelis Basic which is used for both deep treatments and augmentation of different areas of the face including the lips.
Esthelis Soft is used to treat particularly sensitive areas of the face and is injected into the superficial dermis, so can be used to smooth crows feet lines around the eyes, peri-oral lines and forehead wrinkles and to define the lip line.
Esthelis Men has increased viscosity to deal with forehead lines and furrows, scarring and deep facial lines.
Fortelis is a thicker product that is used to treat deep wrinkles and creases as well as cheek augmentation and chin augmentation and facial re-volumisation.
