Linear Dermal Filler Injection for Outward Lip Reshaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for lip augmentation do not allow for the expansion of the outer surface of the lip to increase its volume sideways while turning it outward, limiting the ability to achieve a plumper appearance consistently.
Innovation Solution
A two-step technique involving superficial linear injection of dermal fillers, such as hyaluronic acid, polylactic acid, or polydioxanone, using a needle or cannula to create tunnels within the lip tissue and inject dermal filler to reshape the lip by expanding it outward, combined with the use of cannabidiol for improved biocompatibility.

1Ease of operation
If conventional injection methods are used for lip augmentation, then the procedure is simple and quick, but the ability to expand the outer surface of the lip sideways while turning it outward is limited
Solution Approach 1:
The injection procedure is divided into two distinct steps: first creating tunnels within the lip tissue using a needle or cannula, then injecting dermal filler into these pre-formed tunnels. This segmentation allows each step to be optimized independently, enabling both operational simplicity and enhanced adaptability for outward lip expansion
Solution Approach 2:
Tunnels are created within the lip tissue before the dermal filler is injected. This preliminary action of forming tunnels ahead of time allows the filler to be deposited in a controlled manner that expands the lip outward and increases volume sideways, achieving results that conventional direct injection cannot accomplish
2Volume of stationary object
If larger volumes of dermal filler are used to achieve plumper lips, then the lip volume increases, but the natural appearance and consistency of augmentation are compromised
Solution Approach 1:
The dermal filler is injected into specifically created tunnels within the lip tissue, allowing precise control over the local distribution and placement of the filler. This targeted approach ensures that even larger volumes of filler are deposited in a manner that maintains natural appearance and consistent augmentation results
Solution Approach 2:
The conventional direct injection method is replaced with a two-step system involving tunnel creation followed by controlled filler deposition. This substitution of the injection mechanism allows for more precise control over filler placement and distribution, achieving consistent natural appearance regardless of the filler volume used

AI summary
Introduced here are novel techniques and tools for augmenting the lips through superficial linear injection of dermal fillers. At a high level, these techniques are representative of a two-step approach to augmentation. In the first stage, an implement that is appropriately positioned inside a lip can be moved sideways—an action referred to as a “side push.” In the second stage, dermal filler can be ejected from the implement so as to fill the resulting void. These techniques can be used by healthcare professionals to reshape the lips for medical or aesthetic purposes. These techniques were developed in an attempt to permit augmentation of the outer surface of a lip so as to increase its volume by expanding sideways while turning the lip outward. Presented here are also tools to improve the accuracy of injection. With these techniques, the desired result-namely, a plumper lip—may be readily and consistently achievable.
