TL;DR: HA filler typically lasts 9-12 months in most areas. The cadence that maximizes rebook rate has 5 touches across that window: Month 3 (selfie photo prompt), Month 6 (halfway nudge), Month 8 (educational), Month 9 (refresh window opens), Month 10 (last call). Most spas only send 1 reminder; the 5-touch cadence doubles rebook rates.
The 5-touch filler rebook cadence
Month +3 — Photo prompt
{{first_name}}, would you mind sending a quick selfie? We love comparing pre/post for our clients' files.
Why it works: gets the client looking at their result, plants the maintenance seed, gives you a photo for the chart.
Month +6 — Halfway nudge
{{first_name}}, you're at the halfway point of your filler. Most clients book their refresh around month 9. Want me to put a hold on the calendar?
Month +8 — Educational email
Long-form email about how filler integrates over time and why timing the refresh matters. Soft CTA to reschedule link.
Month +9 — Refresh window opens
{{first_name}}, this is your refresh window. {{week_dates}} are open. Reply YES to book.
Month +10 — Last call
Last call — let me know if you want to refresh or push.
Variations by area
Lips (6-9 months)
Lips lose volume faster due to constant movement. Push the cadence forward by 2-3 months.
Cheeks / chin (12-18 months)
These areas hold volume longer. Push the cadence back by 3 months. Send the Month 3 photo prompt, then skip to Month 9 educational, Month 12 refresh window.
Tear trough / under-eye (12+ months)
Same as cheeks. Conservative cadence.
Sculptra (different mechanism, 6-month cycles)
Sculptra builds collagen over 6-month cycles for the first 1-2 sessions, then stretches to annual maintenance. Cadence: Month 1 aftercare check, Month 3 progress, Month 5 next-session prompt, Month 6 book it.
The auto-rebook-at-checkout move
Same logic as Botox: at the current filler visit checkout, ask: "Most clients refresh in {{interval}} — should I put a soft hold on {{date}}?" Soft holds convert 60-80% to confirmed bookings.
Frequently asked questions
How long does HA filler actually last?
Brand and area dependent. Restylane Lyft and Juvederm Voluma can last 18+ months in cheeks. Lips run 6-9 months. Average across products and areas: 9-12 months.
Should clients refresh before they fully metabolize?
Yes. Refreshing while there's still some product in place gives a smoother result and uses less new filler. Waiting until full metabolism means starting over volumetrically.
What if a client wants to wait longer?
Document it, accept it, and queue a Month 12, Month 14, Month 16 cadence. Don't push.
How do I track filler timing across multiple injection sessions?
Your booking software's chart notes should record: product, syringe count, area, batch number, and intended refresh date. Most med spa EHRs (Aesthetic Record especially) support this natively.
