I am 18 years old. What is the best option for the smile lines I have? (Photo)

The nasolabial folds can be softened with fillers such as Belotero Balance, or Restylane Refyne. Depending on the anatomy of your face, thread lifting will also help to lift your cheeks slighly and reduce the crease in the nasolabial folds. You can also combine this with chemical peels to resurface the skin and help fill in the fine lines around the mouth. I would recommend seeing an expert for a full consultation. 

Hello,Thank you for your question and picture. A filler like Voluma in your lateral cheeks may help pull out the lines around your mouth. A Fraxel laser treatment is another option. It will help stimulate collagen growth which will tighten the skin. Please consult in person with a local physician to determine the best course of action. Good luck!
