Perception drift is real. Many of us have likely, at some point, looked in the mirror, spotted a wrinkle or expression line, and thought: I need Botox. While the muscle-freezing injection is one of the less invasive cosmetic procedures for treating some signs of aging, it still requires guidance from a professional who can determine whether it is, in fact, right for you right now. Before you schedule an appointment, here’s a refresher on how Botox works and expert advice on when to make it the next step in your cosmetic aesthetics protocol.
Does Botox treat or prevent fine lines and wrinkles?
It does both. In a nutshell, Botox works by helping muscles relax. Double-board-certified facial plastic surgeon Dr. Jennifer Levine, MD, explains to ELLE that the injections treat expression-related wrinkles by reducing the contractions that repeatedly fold the skin. Dynamic lines appear with movement; static lines remain when the face is resting. Botox works particularly well on dynamic lines, while deeper static creases may need additional treatments.
In more technical terms, Manoj T. Abraham, MD, F.A.C.S., founder of NYFACEmd further explains that “Botox works by blocking a specific molecular neurotransmitter called acetylcholine. When Botox is administered very precisely by an expert injector to the tiny muscle fibers under your skin, these muscles relax and the lines and wrinkles smooth out,” says Abraham. “This is not only useful to treat and smooth out these lines, but if you start early enough, before you have too many of these lines, it can prevent these lines from forming in the first place.”
From a preventive perspective, Levine says that by reducing the repeated folding that skin does naturally, it may help keep expression lines from becoming more deeply established. “The goal is to preserve a pleasing balance of movement while softening the forces that contribute to creasing. That requires a detailed understanding of which muscles to relax and which movements to preserve,” Levine says.
Who are the best candidates for Botox?
Botox is for adults. But the age range when you can start varies greatly. Levine says that adults who are noticing expression-related wrinkles and would like to soften them are often good candidates, provided their medical history supports treatment.
When deciding which of her patients are good candidates for Botox, Levine takes a very holistic approach. “I approach Botox by looking at the entire face. Facial muscles work in different directions: some elevate our features, while others depress them or pull downward. Carefully relaxing selected muscles can soften wrinkles and, in appropriate patients, reduce downward pull to create a more balanced appearance. This principle applies around the brows as well as in the lower face,” she explains.
Assessing how muscle activity influences overall facial appearance also guides Levine’s recommendations to her patients. “Two people can have similar forehead lines but very different anatomy: one may be using their forehead muscle to help support a heavy brow, while the other is not. Their treatment plans should reflect that difference,” says Levine. “The artistry comes from understanding how a small adjustment to one muscle can influence the expression of the whole face.”
Abraham says that for younger patients in their 20s and 30s, Botox can treat early expression lines and prevent deeper ones from forming. “The key is to do a gentle, precise treatment to relax the lines while maintaining natural expressions,” he explains, adding that for patients in their 40s, 50s, and older with deeper lines, Botox alone may not be sufficient. “In addition to Botox, these patients may need other treatments like fillers, laser resurfacing, and possibly a facelift or eyelid lift to achieve the best improvement. After surgical treatments like facelifts, blepharoplasty, or eyelid lifts, I highly recommend keeping up with Botox treatments to maintain the results of the lift and keep areas smooth,” Abraham says.
When should someone consider getting Botox?
Both Abraham and Levine agree that Botox should be considered when expression lines begin to bother you. “A crease that starts to linger after your face relaxes can also be a useful signal,” says Levine—adding that there is no single age at which everyone should begin. “Muscle strength, skin quality, anatomy, and personal preferences matter more than a birthday. Treating appropriate wrinkles as they develop may help limit further deepening, while allowing us to preserve natural expression,” Levine adds.
Levine also notes that long-term evidence for prevention remains limited, so patients should understand that Botox cannot guarantee they will never develop wrinkles. “Treatment should respond to a specific concern and an anatomical assessment, rather than an assumption that everyone needs to start early.”
What areas of the face does Botox treat?
According to Abraham, common places to treat include the number “11” sign caused by furrowing your brows together, the bunny lines along the top of the nose that form when scrunching, the horizontal lines across the forehead that form when elevating the brows, crow’s feet lines around the eyes when squinting, marionette creases at the corner of the mouth from frowning, “smoker’s lines” around the mouth from pursing the lip (even in nonsmokers), “peau d’orange” or orange-peel-like dimpling and pitting at the chin from mentalis muscle activity, and neck bands from the platysma muscle in the neck.
How long before you see results from Botox?
Expect to start to notice a difference in both skin and muscle activity where Botox was injected, typically within three to five days after the treatment. However, Levine says that the full effect on forehead lines, frown lines, and crow’s feet may take up to 30 days.
You may be able to help the injection kick in faster, though. “I have patients who ‘exercise’ the area injected by making the facial expression that causes the lines to help these muscles take up the medication more quickly,” Abraham shares. “There are some Botox competitors like Dysport (two to three days) and Daxxify that kick in a bit sooner (one to two days), and there are newer neuromodulators that are currently being developed that will have even quicker onset,” he explains.
How long does Botox last?
Initially, you can expect the Botox to last about three to four months. “This is good news because if you don’t like the results for whatever reason, the effect is always temporary and will wear off,” says Abraham. “The bad news is that pretty much everyone loves their Botox result, so the key here is consistency. If you come in for your next treatment before the Botox effect has worn off, the Botox will start to last a few weeks longer each time.” He explains that this is because the muscle fibers that are causing the wrinkles start to atrophy or weaken from lack of use. “It’s like not going to the gym,” he illustrates. Getting treated more frequently than every three months can increase the risk of those muscles becoming immune to the treatment. The treatment then becomes ineffective, similarly to getting an allergy shot, if your body is exposed to the medication too frequently.
The longer you’re able to stretch the interval between Botox treatments, anywhere from three to six months, according to Abraham, the longer you can prolong the effects of the treatment over time. Don’t start then stop altogether, though. “The key is consistency. If you let the Botox wear off and the muscles get back their activity, the lines will start to re-form,” says Abraham.
Does lifestyle impact whether or not someone is a good Botox candidate?
Lifestyle influences both skin aging and what someone wants from treatment, Levine points out. “Sun exposure and smoking contribute to changes that Botox alone cannot address, making sun protection and good skin care essential parts of maintaining results. Someone whose work relies heavily on facial expression may prefer particularly subtle treatment. Travel, upcoming events, and comfort with ongoing maintenance also influence the plan.”
Abraham also shares that there is some evidence showing that those who exercise frequently and are metabolically active break the Botox down a bit quicker. He says these patients may need a higher dose of Botox and more frequent treatments.
Ultimately, both experts agree that the treatment should suit the person’s anatomy and everyday life. “Preserving the warmth of a smile, the openness of the eyes, and the individuality of expression is central to a beautiful outcome,” Levine concludes.
