What "aftercare" actually means for Botox

Botox (botulinum toxin) is injected into specific facial muscles to temporarily relax them. The medicine takes time to bind to nerve endings and begin its effect. Aftercare in the first hours and days is about preventing the medicine from spreading to neighbouring muscles and not interfering with the binding process. After about a week the toxin is fully bound and standard aftercare can resume normal activity.

The aftercare advice that follows reflects current UK clinical consensus from PSA-recognised registers (Save Face), product manufacturer guidance, and the published clinical literature. Your specific practitioner may have additional instructions based on the areas treated and your medical history — follow theirs first.

The first 4 hours

• Stay upright. Do not lie down completely flat for 4 hours after the procedure. The reasoning is theoretical (preventing gravitational migration of unbound toxin) but the advice is universal across UK practitioners.
• Do not rub, massage or press the injection sites. Mechanical pressure could theoretically push the toxin into neighbouring muscles before it binds. Avoid touching, including resting your face on your hands.
• Move the treated muscles gently. Some practitioners advise active frowning, eyebrow-raising or smiling several times in the first hour to help the toxin bind to the intended muscles. Others say this is unnecessary. Follow your practitioner's specific guidance.
• Avoid makeup over the injection sites for 4 hours. The needle entry points need time to close.
• Stay cool. Heat causes vasodilation and may increase bruising risk.

The first 24 hours

• Avoid strenuous exercise. Vigorous exercise raises blood pressure and increases bruising risk; some practitioners also worry it could affect toxin distribution. Light walking is fine.
• Avoid hot showers, saunas, steam rooms, hot tubs and sunbeds. Heat exposure can dilate blood vessels and worsen bruising.
• Avoid alcohol. Alcohol is a vasodilator and an anticoagulant; both increase bruising and swelling.
• Sleep on your back if possible. Pressure on the treated area is best avoided overnight.
• Do not use facial treatments or harsh skincare over the injection sites for the first 24 hours. Hold off on retinol, AHAs, vitamin C and active acids on the treated areas.
• Light cleansing and moisturiser are fine from 4 hours onwards. Use clean hands and a gentle product.

Days 2–7

• Onset of effect. Most patients notice subtle changes from day 3, with clearer effect by day 5. Full peak effect is typically at day 10–14.
• Bruising. Visible bruising peaks at 48–72 hours and usually fades over 5–10 days. Arnica gel may help marginally; concealing makeup is fine from 24 hours onwards.
• Headache. A mild headache for the first 24–48 hours is common. Paracetamol is fine; avoid ibuprofen and aspirin for the first 24 hours unless prescribed otherwise, as they can increase bruising.
• Resume exercise from day 2–3. Most practitioners allow normal exercise from day 2 onwards.
• Avoid facial massages, microneedling, lasers and chemical peels on the treated area for 1–2 weeks.

The 2-week review

Reputable UK clinics include a complimentary 2-week review specifically to assess the result and address any asymmetry. By 14 days the toxin has fully bound to nerve endings and the final effect is visible. Common things picked up at the 2-week review:

• Brow asymmetry — usually corrected with a small top-up to the under-treated side;
• Persistent residual movement in a small area (sometimes called "peaking") — corrected with a focused micro-dose;
• Inadequate effect — can indicate undertreated dosing for that patient's muscle bulk and may need supplementation.

If your clinic does not offer a 2-week review, this is itself a signal about the quality of practice.

Beyond 2 weeks: the "normal" phase

• Peak effect from day 14 onwards, typically lasting 3–4 months. Some patients experience longer duration with repeat treatments as muscle memory adjusts.
• Resume all normal facial treatments after 2 weeks: microneedling, chemical peels, lasers, facial massage and similar.
• Sun protection. Year-round SPF 30+ is the single most useful skincare habit for protecting a refreshed look.
• Top-ups. Most patients book the next session 12–16 weeks after the last. Going earlier than 12 weeks is generally not advised because nerve-ending recovery is not complete and resistance can develop over time with frequent dosing.

What to call your practitioner about

• Drooping eyelid (ptosis) that affects vision — usually appears in days 7–14 and may benefit from apraclonidine eye drops in the interim.
• Significant brow asymmetry at the 2-week mark — easily correctable.
• Severe persistent headache beyond 72 hours.
• Signs of infection: spreading redness, warmth, pus, fever.
• Persistent muscle weakness spreading beyond the treated area.
• Inability to fully close the eye or smile symmetrically beyond the expected pattern.

Aftercare myths worth ignoring

• "Don't fly for 48 hours." No published evidence supports this. Most UK practitioners do not advise it.
• "You must do facial exercises every hour for the first day." Mixed evidence; many practitioners no longer recommend this.
• "You'll need top-ups every 6 weeks." No — standard interval is 12–16 weeks. Clinics suggesting 6-weekly top-ups are either treating with sub-therapeutic doses or are commercially motivated.
• "Sleeping a certain way makes it last longer." Not supported by evidence. The toxin is fully bound within hours.
• "Apply ice for an hour." Light cooling for 5–10 minutes is fine for bruising. Prolonged ice is unnecessary and uncomfortable.

If you want a longer-lasting result

The single most useful predictor of longer-lasting Botox is consistent SPF 30+ daily, no smoking, adequate sleep and a balanced diet. The muscle effect wears off as nerve endings recover at a biological rate that aftercare cannot meaningfully alter. What you can influence is the underlying skin quality.

Booking the next session

Most patients book their next session 12–16 weeks after the last.
