As we age, we all get those "cracks" and "crevices" on our face. Some of these are "static" - that is they develop over time from "sun damage", perhaps trauma. There are also "dynamic" lines which can develop from muscle action (we all use our facial muscles to "frown", "smile", etc. and over time these lines can occur (botox can help with this but that's the subject of another upcoming blog.)
The best thing you can put on your face? SUNBLOCK! Use of sunblock can heop prevent or lessen the so-called "free radical damage" that the sun's rays (uv band) does to our face (and all of our exposed skin). Also the uvA band is particularly dangerous in causing or facilitating the development of skin cancers.
The most common fillers used are "alpha hydroxyl acids" which are naturally occurring in our body. Products you may be familiar with include: Restylane, Juvederm, etc.
These products are "hydrophilic" that is they "attract" water and this helps their effect and "plumping" action where they are used. Juvederm XL and Juvedern XL Plus are the only products approved by the FDA to claim to last a year. The inclusion of "lidocaine" in these products makes them less easier to inject for the patient, however I also often can add a "block" such as an "infaorbital" nerve block which can further mitigate the pain of an injection. I also have used a compounded anesthetic cream which can be applied before the injections which is also effective.
Common areas to treat include: nasolabial folds, "lip lines", "marionette" lines (downturning from the mouth); and these products can do a good job of keeping you looking "younger" and "fresher" in the years before other facial rejuvenation procedures (such as a facelift) might be a better option to consider.
Ther are "deeper" fillers such as Perlane and Volume which are injected deeper than those mentioned above and can be quite effective to restore some lost volume---- but that's the subject of an upcoming blog.......
