My both upper and lower lips are inside. They are disappearing. How can I get my lips bigger and fuller? (photo)

Lip augmentations with fillers is a great option to improve the fullness, suppleness and symmetry of the lips. Results can be very natural-looking and will feel very natural. I prefer to use a micro cannula to inject the lips to prevent bruising. Look for a cosmetic dermatologist or plastic surgeon who is an expert in fillers to discuss your desired results and concerns and go over the cost of your procedure. 
I hope this helps.

Lip augmentation with Hyaluronic acid, a natural ingredient found in our skin, is the perfect treatment for you because it will add volume and definition to your lips. It will make them look fuller and plumper, still giving you a natural result. But there are a few key things to consider when it comes to this treatment; first of all, use recognized brands of Hyaluronic acid like Restylane or Juvederm, also; you have to find a Plastic Surgeon, Medical Aesthetician, or a Dermatologist that had performed these treatments before that will accomplish your expectations achieving natural results so that you can have a wonderful smile in your pictures.

Filler needs to be placed in the proper place for you to achieve that goal. Pushing the lips out is a different technique than just getting them filled. Be cautious who you choose to fill and that they understand exactly what you want.
