Smile muscles, or corrugators, are those muscles around the mouth and cheeks that cause the lower portion of the face to turn upwards when a smile is achieved. These muscles are responsible for not only smiling but also drawing the mouth down into a purse or tight lipped expression as well. Not only does this help to build cheek muscles for chewing and smiling, but if you smile at enough people, will build great friendships as well.

Place your longest finger over the lips from end to end across the face. This will tell you how wide your smile should be to do the exercises to build the smile muscles.

Draw the muscles of the mouth tight by pushing the lips together as if you are going to whistle. Hold this for 10 seconds and release. Repeat this exercise 10 times a day for a week and then 20 times a day for a week to strengthen the muscles.

Tighten the muscles in the cheek area by smiling as wide as you can. Hold this pose for 15 seconds and do this for 10 repetitions. Repeat this exercise every day for a week and then 20 repetitions for a second week.

Apply moisturizing lotion around the mouth and on cheeks before and after exercises, as this will help to keep the areas moisturized.


  • Using lotion on the face prior to and following the exercises will help to re-moisturize the areas. When you are doing this type of exercise, wrinkles and folds can be created by the repetitive movements being used to build muscle. The wrinkling and deepening folds can be quieted by applying lotion during the morning and evening hours after showers as well. Lines around the lips will be seen after the exercises, and it is important to use a lip balm that will moisturize and protect against sun damage as well. Sun damage can also cause wrinkles in these areas, so it is best to use an SPF 50 sunscreen when any outdoor activity is taken on.
