How long Botox lasts: it differs by area, so when should I get a touch-up?

Wrinkle Botox lasts 2 to 3 months on average, and Botox for large muscles such as a square jaw takes longer than that for the reduced muscle to return to its original size. Botox is a medication that blocks the signals nerves send to muscles, so as time passes and new nerve endings grow, muscle movement gradually returns. The dose injected, the size of the muscle, and how much you usually use your facial expressions determine how long it lasts.
Why does Botox last for a set period?
Botox (botulinum toxin) blocks the release of acetylcholine from nerve endings so that muscles contract less. Over several months, the blocked nerve endings sprout new branches and restore signal transmission, and muscle movement returns accordingly.
That is why Botox does not suddenly stop working one day but fades gradually. Expression wrinkles start to show again as movement slowly returns, and with a square jaw, the reduced muscle returns to its original size over several months.
How long Botox lasts by area and when to get it again
Areas with small muscles that are used often for expressions, such as between the eyebrows, the forehead, and around the eyes, regain movement relatively quickly, while large, thick muscles like the masseter return slowly from their reduced size. Skin Botox, injected into the shallow layers of the skin, acts on the sebaceous glands and fine muscles rather than the main muscles, so its duration feels shorter.
At FACE FILTER Clinic Suwon, our recommended guideline is as follows: wrinkle Botox lasts 2 to 3 months on average and is repeated at 3 to 4 month intervals, square jaw Botox is repeated at 4 to 5 month intervals, and skin Botox lasts 1 to 2 months on average and is repeated at 2 to 3 month intervals.
Timing of Botox touch-ups and resistance
A touch-up is an injection that supplements any left-right differences or remaining movement after the effect has fully appeared. Because Botox takes from several days to two weeks to take effect, whether a touch-up is needed is usually checked around two weeks, and adding more before the full effect appears can make it work too strongly.
Getting large doses frequently at short intervals can lead the body to produce antibodies against the toxin, causing resistance that reduces the effect. Bruising and swelling after treatment are mild and settle soon, and if your eyelids droop or your expressions look unnatural, please contact the clinic. If you are pregnant or breastfeeding, please let us know before treatment.

FAQ
Q. Why does Botox seem to last shorter and shorter?
A. Repeating it at short intervals or getting a large dose at once can lead to antibodies against the toxin, causing resistance in which the effect shows less. Expression habits and changes in muscle mass also have an influence, so we review the dose and interval together.
Q. Do wrinkles get deeper once Botox wears off?
A. When the effect ends, muscle movement simply returns to how it was; wrinkles do not become deeper than before the injection. In fact, because folding stress decreases while the muscle is used less, it may help slow down how quickly wrinkles deepen.
Q. When should I get a Botox touch-up?
A. Around two weeks, when the effect has fully appeared, we check for left-right differences or remaining movement and supplement only the areas that need it. Adding more before then can overlap the effects and make it work too strongly, so the timing of a touch-up is decided together with our medical staff.
