How Does BOTOX® Cosmetic Work?
BOTOX® Cosmetic is formulated with botulinum toxin A, which is derived from Clostridium botulinum bacteria. It is a neuromodulator, and works by affecting how nerve impulses are transmitted. BOTOX® Cosmetic specifically blocks the release of acetylcholine, a chemical responsible for activating the muscles in your forehead that contract when you frown or concentrate. By preventing your forehead muscles from contracting, BOTOX® Cosmetic smooths out fine lines and wrinkles, erasing years from your appearance.
Reasons Your Eyebrows May Droop After a BOTOX® Cosmetic Treatment
Keep in mind that this blog is about why your eyebrows might droop after a BOTOX® Cosmetic treatment, so of course, we’re talking about all of the ways that it could happen. However, while there is no guarantee that you can prevent your eyebrows from drooping after a BOTOX® Cosmetic treatment, it is generally a safe and effective treatment that millions of people utilize every year to address signs of aging.
With that being said, here are some of the reasons why your eyebrows may droop after a BOTOX® Cosmetic treatment:
Injection Placement and Technique
The most common reason your eyebrow may droop after BOTOX® Cosmetic is incorrect placement of the injections. Forehead wrinkles are treated by injections in the frontalis muscle, which is the muscle used to raise your eyebrows. If too much BOTOX® Cosmetic is injected into this muscle or the injections are placed too low on your forehead, it can relax the frontalis muscle too much and cause your eyebrows to droop.
Your Individual Anatomy
Your injector’s knowledge of facial anatomy is a crucial part of a successful BOTOX® Cosmetic treatment. The more familiar they are with the structure and muscles of your facial anatomy, the safer your treatment will be. However, individual facial anatomy also plays a role. If you naturally have heavy brows, relaxing your frontalis muscle too much may cause excessive drooping. Additionally, if you have ever had a problem with weak forehead muscles or a sagging brow, let your provider know so they can adjust accordingly.
Product Migration
BOTOX® Cosmetic is designed to stay in the area where it is injected. However, it may migrate if injected incorrectly or if you rub or massage your face after treatment. If your BOTOX® Cosmetic injection disperses or moves, it will not only decrease your treatment’s effectiveness but may also result in unintended side effects like a saggy brow.
How to Avoid Eyebrow Drooping After a BOTOX® Cosmetic Treatment
The most critical part of undergoing BOTOX® Cosmetic treatments is choosing the right injector. There are so many options available, and you may be tempted to take advantage of a lower-cost provider. However, especially when you are trying BOTOX® Cosmetic for the first time, you want to be sure that your injector is well-versed in the anatomy of your face and skillful enough to strategically place injections where they will have the optimal effect.
Below are some tips for making the most of your BOTOX® Cosmetic treatment—and avoiding drooping brows.
Communicate With Your Injector
While your injector is a professional who knows how BOTOX® Cosmetic works and how to administer it, they can only work with the information they have. Therefore, they need to know if you’ve had BOTOX® Cosmetic or a similar neuromodulator treatment before and if you have a history of weak brow muscles or eyebrow drooping.
Start Small
If you’ve never had BOTOX® Cosmetic treatments before, it’s better to err on the side of a lower dose than over-treating and ending up with a sagging brow. Once you know how your face responds to the treatment, your injector can tweak the dosage to perfect your results.
Follow Your Injector’s Post-Treatment Instructions
Your injector will give you instructions about what to do and what not to do after your BOTOX® Cosmetic treatment. One of those “do’s” is to avoid rubbing or massaging the treatment area, as it can cause BOTOX® Cosmetic to migrate, ending up in an unintended area and causing your eyebrows to droop.
