Here's how it happens: After a Botox session, a patient tries to make a facial expression, but Botox-injected muscles can't move. Nearby muscles contract instead, causing new wrinkles. The process is called “recruitment” of the nearby muscles.
And if you're wondering if Botox works if you already have wrinkles, the answer is a resounding YES. In fact, smoothing out facial wrinkles and fine lines, like laugh lines, crow's feet, frown lines, etc., is the primary FDA-approved purpose of Botox injections.
The appearance of fine lines and shallow wrinkles will lessen quickly, and deeper, harsher lines and wrinkles will take more than 14 days to fade. Around 14 days, all the treated areas will look smoother, fuller, and more youthful. Wrinkles and fine lines will disappear or appear smaller and softer.
One of the most common reasons that people do not see full results after their Botox treatment is because the dose used was too low. Although many people have fears of Botox treatments, the recommended doses are provided to give natural and full results.
Results are not usually visible the same or the next day. It takes time for the BOTOX® injections to kick in because the BOTOX® binds at a connection point between muscles and nerves called the motor endplate. Injections are absorbed by the nerve cells first and take time to work into the muscles.
Generally speaking, Botox injections in the forehead last for approximately 4 months. However, the specific longevity of the treatment depends on the specific dosage, your tolerance to the product, exercise level, and other factors.
When people see lines forming after BOTOX wears off, they assume treatment made their wrinkles worse. Actually, your face simply returns back to its natural state. No new wrinkles or lines are ever caused by these injections.
As soon as you've had your very first Botox injections, you might be panicking that nothing looks different. Don't worry – that's totally normal. The first time botox is injected, it takes time to act. In fact, it's possible that it may take 2-8 days to start seeing a difference.
When some people see their wrinkles form again after the rejuvenating effects of Botox wear off, they assume that the treatment made their wrinkles worse. This isn't true at all. In fact, regular Botox use can actually retrain certain muscles to move less, leading to smoother skin with less Botox over time.
So what could be the reasons behind Botox not working on forehead wrinkles? Some of the most common ones involve not getting enough Botox units for your skin issue, Botox not being injected correctly, or it could also be that some wrinkles are at a certain depth and could only be corrected so much.
The most common reason that Botox does not work is that not enough was given. Botox is not a one size fits all treatment and the same dosage does not work for everyone. Some individuals may need additional Botox to reach an effective level of muscle weakness. The Botox may also be old, overdiluted, or fake.
The first thing you'll notice immediately after Botox injections are little bumps and dots of blood that look just like mosquito bites. These go away in 20 minutes to half an hour. But you won't notice the skin-smoothing effects between three to five days (and up to two weeks).
The traditional Botox schedule calls for new injections every 3-4 months to treat glabellar lines—the horizontal lines on your forehead.
In most cases, Botox begins to work fully within the first week after treatment, so by day four you should be able to see a slightly noticeable difference in the appearance of the areas that were treated. If this is your first treatment, you may experience a “heavy” sensation in the treatment areas.
Cosmetic Botox injections will make you look and feel fresh and young. The people around you are bound to notice and most people will simply pay you a compliment and that's it.
Botox takes between 3-7 days for the results of treatment to be fully noticeable. At times, results may look slightly uneven at first, because the Botox may “kick in” at different rates.
While not very common, some people can actually develop a resistance to Botox which means it either doesn't work very well, doesn't last long, or sometimes doesn't work at all. Because botulinum toxin is produced by bacteria, the immune system may recognize it as an invader and deactivate it.
In addition to injectables and skincare, lasers and chemical peels are in-office procedures that dermatologists offer to help get rid of forehead wrinkles. “Resurfacing lasers cause controlled damage to the skin, taking advantage of its ability to heal itself and create new collagen,” explains Zeichner.
