Botox For Smile Lines

Botox is used for smile lines around the eyes. If you want your smile lines around your mouth treated it is best to use fillers such as Juvederm or Restylane.

Smile Lines and Botox

Patients will often ask me if I can "get rid of this line" in regards to facial lines and wrinkles that may not necessarily contribute to the appearance of age or fatigue.
My strong feeling about the softening of facial lines and wrinkles is this:
  • if it doesn't 'age' you, and it doesn't make you look tired or worried, then don't spend your hard-earned money trying to make it go away.
  • Some lines actually do add warmth and character to the face, and an older face with NO lines usually looks a bit odd.
  • Some smiles that may add age to the face can be treated conservatively with Botox.

Smile lines around the eyes, also known as "crow's feet"...

Smile lines around the eyes, also known as "crow's feet", are among the best areas treated by Botox. Approximately 10 to 12 units of Botox per side are required for good correction of the smile lines.

Botox for smile lines

Thank you for your question. Botox can help with the smile lines, but I is important to define where the lines are. Some patients refer to the crows feet (outer eye skin) as smile lines and Botox is very effective here. Some refer to the nasolabial folds as the smile lines. Fillers are much more effective here and Botox is not.

Fillers are best for treating smile lines

Since Botox relaxes muscles, it is not good to use for smile lines because it would affect your ability to smile!  So, fillers are usually the best solution for these lines, like Restylane or Juvederm.  Lasers may also be utilized in some cases.

Treating smile lines

Smile lines ("crows feet") around the eyes may respond very well to Botox. Other smile lines such as the ones over the cheek/midface area and nasolabial line don't usually respond very well to Botox. In many patients, a filling material with hyaluronic acid works better in those areas, instead. A discussion with your surgeon will help you figure out what would be best for your face.

Botox for Smile Lines

The answer to your question depends on how you define smile lines. Two practitioners that answered this question focused on different areas, one the mouth and the other the crow's feet (sides of eyes). The crow's feet (the wrinkles on the sides of the eyes that are accentuated when we smile) are excellent candidates for Botox and in most cases, we can achieve complete resolution of these lines using Botox.

But if the smile lines you are referring to are the creases that exist between the sides of the nose and the corners of the mouth, then Botox is not an option and dermal fillers like Restylane would be a great choice.

Smile lines

Often times, the best way to treat smile lines is with a combination of subtle filler in the cheeks to lift sagging skin and to stimulate collagen production with microneedling. Microneedling will also help to tighten this skin and smooth out fine lines. A good guideline for all treatments is that for the fullest correction you should address both the underlying structures and the overlying skin's texture and tightness.

Botox smooths out crow's feet; fillers help with lines around the mouth

Thanks for your question. Botox is particularly good at smoothing out crow's feet, the lines around the eyes, whereas injectable fillers are great for the lines around the mouth (Botox relaxes your muscles, so it would affect your smile). Botox and fillers should be injected by a certified plastic surgeon or dermatologist; ask for a consultation so they will be able to tell you what would give you the best results.

Smile lines at the corner of your eyes

If the wrinkles at the corners of your eyes appear only when you make a facial expression, like smiling, then Botox would be more suitable. Botox treats "dynamic" wrinkles.

Fillers would be better for you because the wrinkles are visible even when your face is in a neutral expression. This means that they are "static" wrinkles, and fillers is the right treatment to smooth them away.
