Similar to bruising, slight visible bleeding may occur at the injection site after Botox has been injected. This can happen in a similar way to how bruises can occur, as the needle enters the skin and cuts a small capillary or vein, causing blood to flow out of the injection site. This bleeding should be mild and stop very quickly. The likelihood of bleeding after Botox injections may depend on the experience and skill level of the injector, as well as if you are particularly prone to bleeding.
Many blood vessels are located under the face, including arteries that supply oxygenated and nutrient-rich blood, and veins that return “used blood” to the body. These vessels form a mesh-like network around the eye, its cavity, and surrounding structures. Research suggests that any injection directed into the nose, forehead, or side of the eye has the potential to enter any of these arteries and force fillers back into the blood vessels, causing them to block. Botox has had an undeserved reputation for causing frozen faces or permanently surprised expressions.
However, the risks are very small with Botox, but just like with any other medical or cosmetic treatment, things can go wrong. Injection-induced pain depends mainly on your skin and the skill of the person injecting you. Some people have bad experiences with Botox due to errors, but you can avoid this by making sure your injector is qualified and regulated, and that you have a proper consultation and review appointments booked. So even though your brain can fire and signal your body to move a particular muscle, Botox effectively blocks that shot and prevents the muscle from moving.
Dermal fillers are injections of collagen or other substances used to smooth wrinkles and lines on the skin. These side effects could be attributed to a technical error (someone who is giving you Botox treatment and doesn't know what they are doing). That's highly unlikely, but it's a more than compelling reason not to go looking for Botox without consulting a medical professional first. As with any injectable treatment, there is always more to consider than with non-invasive treatments, and you should definitely do your homework.
If you are not undergoing treatment by a qualified doctor, you should refer you to a medical professional (the person who prescribes Botox) to check that you are fit for treatment. Botox injections are effective in eliminating any type of facial wrinkles, such as forehead wrinkles, crow's feet, puppet lines, nasolabial folds, eyebrow lines, and eye wrinkles. If you're in the right place, your doctor or injector will gladly answer any questions you may have and will likely answer your questions before you have to ask them. Botox has been regulated for a long time and is actually a very safe treatment, even compared to dermal fillers.
