Jaw Botox: Nothing Changed in 2 Days — Normal?

Two Days After Jaw Botox and Nothing's Changed — Did Something Go Wrong?

It's pretty common to feel a little uneasy when you look in the mirror the morning after your jaw Botox procedure. You look exactly the same as yesterday. And if two days pass without any noticeable difference, it's natural to wonder, "Did something go wrong?" The good news is — this is completely normal and happens to nearly everyone.

Botox works by gradually reducing muscle activity over time, so seeing no change within the first few days is entirely expected.

Botox Works by Reducing Muscle Activity

Jaw Botox is injected into the masseter muscle* — the muscle responsible for that squared-off jawline.

*Masseter: This is the muscle on the side of your jaw that you use when chewing. The more you use it, the larger it becomes.

Once the Botox enters the muscle, it weakens the nerve signals that tell the muscle to contract. When the muscle can no longer move as actively, it gradually decreases in volume. This process doesn't happen over a few days — it unfolds over several weeks.

Visible Changes Typically Appear Around 2–4 Weeks

If there's no change the next day, it doesn't mean the Botox didn't work. It simply means the muscle needs time to respond. Most patients start noticing a softer jawline around the 2-week mark, with the most noticeable results appearing between 4–6 weeks.

For first-time patients especially, it's more realistic to evaluate your results over a full cycle — typically 3–6 months — rather than expecting a dramatic transformation after a single session.

What the Difference Between 50 Units and 100 Units Actually Means

A higher dose produces a more significant reduction, but it also increases the risk of side effects such as an unnatural facial expression or reduced chewing strength. For this reason, most clinics in Korea typically start with 25–50 units per side and adjust based on how you respond over time.

That said, the placement and distribution of the injections often matter more than the dosage alone when it comes to the final result.

Consistency Is Key to Maintaining Your Results

The effects of Botox are not permanent. Around 4–6 months after your procedure, the muscle gradually regains its movement and begins to return to its previous size. If you wait too long after the effects wear off, your jawline will eventually return to where it started.

If you want to maintain a slimmer jawline, it's more effective to schedule your next session while the current results are still active, rather than waiting until everything has fully worn off.

**Q. It's been a week and I still don't see any change. Should I go back in?** A. One week is still too early to assess the results. Most changes become visible between 2–4 weeks. If there's still minimal improvement after that window, it's not too late to schedule a consultation then.

**Q. I've heard jaw Botox can make chewing uncomfortable.** A. If the dosage is too high or the placement isn't quite right, some patients may experience temporary discomfort when chewing. This typically resolves within 1–2 weeks. If it persists, a dosage adjustment may be worth considering.

**Q. I've heard you can develop resistance to Botox if you get it too often.** A. There have been reports of antibody formation in cases involving very frequent, high-dose treatments. Sticking to the recommended treatment intervals is the safest approach.

Frequently Asked Questions

Q1. How long does it take to see jaw Botox results?

Most people start noticing a softer jawline around the two-week mark, with the most noticeable results typically showing up between four and six weeks. That's because Botox works by gradually reducing muscle activity, and the masseter muscle needs time to shrink from disuse rather than changing overnight.

Q2. Is it normal to see no change two days after jaw Botox?

Yes, this is completely normal and happens to nearly everyone. Botox doesn't produce a visible change within the first few days — it takes several weeks for the muscle to respond, so seeing your usual face right after the procedure doesn't mean anything went wrong.

Q3. What's the difference between 50 units and 100 units of jaw Botox?

A higher dose generally produces a more noticeable reduction in jaw width, but it also raises the risk of side effects like an unnatural expression or reduced chewing strength. Most clinics start with a more conservative dose per side and adjust based on how you respond, since injection placement often matters as much as the total dose.

Q4. How long do jaw Botox results last?

Jaw Botox results aren't permanent — the muscle typically starts returning to its original activity level around four to six months after treatment. Because of that, most people who want to maintain a slimmer jawline plan on repeat sessions roughly on that cycle.
