If you've spent time in online facial aesthetics communities, you've probably come across threads about mouth widening appliances. People experimenting with rubber bands, custom 3D-printed retractors, repurposed orthodontic tools — all chasing the same goal: a wider commissure width.
And the interesting thing? The demand is legitimate. The science is real. They just didn't have a proper product — until now.
What Is Commissure Width?
Commissure width is the horizontal distance between the two corners of your mouth. It's one of the most significant factors in facial attractiveness studies. A wider commissure relative to the face creates a more open, confident, approachable appearance.
Studies in facial aesthetics consistently show that wider smiles are rated as more attractive. Specifically, the "ideal" smile width is roughly equal to the inter-pupillary distance — the distance between your eyes. Most people's natural commissure width falls short of this.
Why the DIY Approach Is Risky
The DIY community figured out the concept — gentle, progressive stretching of the lip commissures. But the execution matters enormously.
Using rubber bands or improvised devices carries real risks:
- Uneven pressure causing asymmetric results
- Non-medical materials irritating oral tissue
- No mechanism for progressive adjustment
- Risk of tissue damage from sharp or poorly finished edges
Looksproject SmileFlex solves all of this. It uses smooth rounded ends designed for lip tissue contact and an adjustable mechanism that lets you progress gradually over weeks — the right way.

The lip commissures are soft tissue — skin, muscle, and connective tissue. Like any soft tissue, they respond to progressive mechanical loading. This is the same principle behind face yoga, neck stretching, and other soft tissue training techniques that have proven results.
10 minutes of daily use with SmileFlex is enough stimulus for the tissue to begin adapting. Over 4–6 weeks, the commissures begin to rest in a slightly wider position, and range of motion during smiling increases. The result: a naturally wider, fuller smile.
