Neurotoxin lasts roughly three to four months. Filler, six to twelve. A facial series works on a monthly cadence. These intervals are known, clinically meaningful, and almost never used as a trigger for anything.
Instead most med spas run a monthly promotional email to the whole list and wonder why the same forty people book. The people who are due are a completely different set from the people who read your newsletter.
Trigger on the treatment, not the calendar
| Treatment | Reminder at | What the message references |
|---|---|---|
| Neurotoxin | Week 12 | The specific area treated |
| Filler | Month 9 | Time since, and a check-in framing |
| Facial series | Week 4 | Where they are in the series |
| Laser package | Per protocol interval | Session number remaining |
| Any first-time client | Day 7 | How they are healing |
That last row is the one people skip and it may be the most valuable. A check-in a week after a first treatment converts a transaction into a relationship, surfaces problems while they are still fixable, and costs nothing on a per-line plan.

Hi Rachel — Nadia at Lumen. Checking in a week on, how's everything settling?
really happy with it! bit of bruising but fading
That's right on track. Ice it if it's tender — and text me if it hasn't cleared by the weekend.
The rebooking message itself
Specificity is the whole game. A generic 'we miss you' reads as bulk mail and gets treated as such. Referencing the actual treatment reads as your provider remembering you.

Hi Rachel — you're coming up on about 12 weeks since your last treatment. Want me to hold a Tuesday or a Thursday?
Thursday please, afternoon if you have it
The line you must not cross
Do not name the treatment, the condition, or anything clinical in a message that could be read on a lock screen by someone other than your client. 'Your Botox appointment' on a shared family iPad is a privacy incident. Keep outbound copy generic and let the client raise specifics — this is both good practice and, if you handle protected health information, potentially a legal requirement. See compliance.
What not to send
- Flash promotions to the whole list. Discounting into a thread with someone's family is how a premium brand stops feeling premium.
- Before-and-after photos unsolicited. Even flattering ones. Especially flattering ones.
- Anything to a client whose last visit went badly. Suppress on any flagged outcome before the rebooking play runs.
- More than one reminder per cycle. If they did not book at week 12, they are not booking at week 13 because you asked twice.
Measuring it
Three numbers
- Rebooking rate by treatment type and by weeks-since-last-visit
- Average days between visits, before and after you started
- Revenue attributed to

For neighbouring businesses with a harder version of the same privacy constraint, see independent pharmacies — where you can say even less.
The second one is the honest measure. Reminders that pull the average interval from 19 weeks down to 14 have added roughly a third of a visit per client per year, which for most med spas is the difference between a good year and a flat one.
