Both fillers are composed of hyaluronic acid and is injected into the skin or just under) in small amounts to restore volume and structure. The hyaluronic acid in Restylane is non-animal which means that no skin tests are needed and that there is a minimal risk of allergic or hypersensitive reactions.

Perlane has larger gel particles and is intended for deeper injection. Results are typically long-lasting, without being permanent. This gives you the freedom of choice to maintain the effect. It will generally last 6-12 months, and with only one re-treatment the effect has in a recent clinical study been shown to last up to 18 months. To maintain the results in the lips, a re-treatment is usually needed within 6 months. 

Please consult with a facial plastic surgeon prior to any facial injectable fillers.
