What filler to choose - Hi my question is, what's the difference between Restylane and Restylane Silk?

Restylane and Restylane Silk are both dermal fillers, but they are designed for different purposes. Restylane is typically used to add volume and fullness to the skin, smoothing wrinkles and folds. Restylane Silk, on the other hand, is specifically formulated for lip augmentation and smoothing lines around the mouth.While both products are made from hyaluronic acid, Restylane Silk has smaller particles, making it suitable for more delicate areas. It aims to provide a subtle and natural enhancement to the lips and the surrounding fine lines. The choice between Restylane and Restylane Silk would depend on the specific aesthetic goals and areas of concern you have. It’s important to consult with a skilled healthcare professional to determine which product is best suited for your individual needs.

They are both Hyaluronic Acid Fillers but, Restylane Silk is slightly thinner than Restylane. This is why Restylane Silk is preferred in the under-eye area. Depending on the volume deficit, Restylane might be indicated as well.  
 

Hello,Good question.  Most injectors that perform "tear trough" treatments (under the eyes) prefer Restylane as this is a smooth gel that is safe, predictable, and offers a solid duration of 9 to 12 months or longer in this area.  Although not FDA approved for tear troughs, this is the most common filler used for this service.  Restylane SILK is a much thinner product which is ideal for fine lines or treatment of the mouth/lips.  It's not clear why your injector would prefer SILK given that Restylane is the better choice as well as a lower price tag.
