Neuromuscular Toxins


Neuromuscular Toxins


The first option, which is most appropriate for active lines or age associated wrinkles that are just starting to appear, is to temporarily weaken or paralyze the muscle that is causing the wrinkle.  Botulinum Toxin type A is a family of neurotoxins that block nerve signals that cause muscles to contract.  The toxin works directly where it is placed, and thus can be artistically used to alter facial expressions.  Botox Cosmetic® is widely recognized, and was the first neurotoxin to be approved for cosmetic use in the United States.  Other manufactures are producing variant toxins that will likely be approved for use in the near future, including Reloxin and PurTox.  These toxins will be differentiated by their time to onset, duration of effect (the clinical effects of Botox Cosmetic® are typically 3 to 4 months), and the distance of effect from the injection site.  Risks include bruising at the injection site, rare chance of an infection, and the possibility of unintentionally affecting nearby muscle groups.  Specific risks should be discussed with your injector when considering treatment.muscle groups.  Specific risks should be discussed with your injector when considering treatment.

Soft Tissue Fillers


The second class of injectable treatments are the soft tissue fillers.  This group is rapidly expanding, and many options are available.  These injectables are more useful for treatment of firmly established wrinkles or larger lines of facial aging (such as the nasolabial folds).   Fillers restore volume to the face and can add structure as well.  Depending on the type of filler and the depth at which it is injected, you can smooth out fine lines on the surface of the skin, fill out deep lines (eg: nasolabial folds), augment soft tissues (such as the lips), or even effectively augment facial bone structure.  All of these injectable fillers are placed by an injection, so the group carries usual risks of bruising, lumpiness, redness, product specific adverse reactions, and in rare cases local infections.
Many options are available in the filler class, with clinical differences being predominantly governed by how long the effects last, as well as how the filler “feels”.  Generally speaking, very soft fillers (that are best for locations such as the lips) tend to have a shorter duration of effect, while fillers that last longer tend to have more structure and are better suited in regions where they will not be palpable (such as the nasolabial folds).  In the past, the most widely used fillers were based on collagen, with sources ranging from bovine to human.  For some collagen formulations, skin testing before injection is necessary to confirm that you will not have an allergic response to the filler.  Collagen based fillers tend to last 3 to 6 months, and for some indications have a very natural feel.

Rested and wrinkled? Oh, the irony

Are the facial wrinkles, lines and folds that happen with aging result purely from the expressions we make? While skin distortion from facial expressions causes many, if not most, of the wrinkles we see on our faces with age, a new study suggests there’s a wrinkle (ahem) in that line of thinking. It turns out, as many experts in facial aesthetics have long assumed, wrinkles also result from "mechanical distortion" during sleep.

Plastic surgeon and lead author Goesel Anson, M.D., clinical instructor of surgery at the School of Medicine, University of Nevada, Las Vegas, and colleagues report in the study published online June 21 in the Aesthetic Surgery Journal that compression, shear and stress force factors result in facial distortion when people sleep on their sides and stomach.
These sleep wrinkles tend to be perpendicular to expression lines and they don’t respond significantly to animation, according to Dr. Anson. Common sleep wrinkles include the lateral oblique forehead crease, radial orbital crease, lateral (vertical) malar crease, medial cheek crease, nasal/lip crease, corner lip crease, oblique marionette crease, preauricular crease and inferior vertical cheek crease, according to the study.

American Society for Aesthetic Plastic Surgery President Daniel C. Mills, M.D., a plastic surgeon in Laguna Beach, Calif., says he has long suggested to patients that some of their facial wrinkles come from sleep positions, especially when patients complain that they have more wrinkles on one side of the face than the other. He’ll ask them how they sleep at night, and often the light goes off in the patient’s mind that, yes, those wrinkles show up on the side of their favorite sleeping position, he says.
“So, these are things that we see on a daily basis, but it’s very nice for the doctors to have written an article about this, quantifying it,” Dr. Mills says.
The researchers not only looked at wrinkles from sleep, but also potential facial skin expansion. Based on available studies, they didn’t find a direct correlation between facial distortion during sleep and skin expansion, Dr. Anson says. However, it’s a logical conclusion to draw from basic science literature and more research needs to be done on the subject matter, she says.

Wrinkles A Quick Fix For Bunny Lines


Think about it: Which area of the face do you normally consider getting neurotoxin injections (better known as Botox, Dysport or Xeomin*)? Many women will tell you the crow's feet, forehead and even "the elevens," which are those pesky lines that form between the eyebrows. But you don't often hear about bunny lines, the wrinkles that form at the top of your nose when you scrunch it. That's likely because it's an area that many of us don't know can be treated because it hadn't occurred to us in the first place.
