摘要 |
<p>Photoactive materials, such as photosensitizers, are used as fluorescent markers for in vivo detection of the distribution of the injected filler material during cosmetic treatments. In one preferred embodiment, liposomal formulated temoporfin is used, as the photoactive component, in very small concentrations along with fillers for cosmetic and wound healing applications. Fillers, which can be used in the invention, include collagen, hyaluronic acids and other synthetic or natural products which are generally used in wound healing, scar reduction and other such medical applications. In a preferred embodiment, the formulated photosensitizer is coupled to the filler so that tracking is possible over longer periods of time A liposomal formulated photosensitizer is injected with the fillers into the treatment area, and is irradiated with laser light shortly after injection. The emitted fluorescence is measured by a special non-invasive device. Thereby it is possible to monitor the injection site and the distribution of the injected solution around the injection site. When irradiated with laser or other light source, the fluorescence of the photosensitizer is detected using a fluorescence detector, which permits tracking the filler at injection site and in the injection volume.</p> |
