In short. A course is a year of your calendar, not an appointment: sessions at four to six week gaps, recovery days after each, and a maintenance interval afterwards.
Key points
- Everything this treatment produces fades over time, so a maintenance interval is part of the honest description of the plan rather than an upsell at the end.
- Some patients choose occasional sessions to hold what they have; some choose to stop and accept the drift.
- Both are legitimate, and the difference between them is a decision rather than a default.
This treatment is usually discussed in sessions, and the currency that matters is the calendar. Each appointment is short. What the treatment asks for is a year of them, spaced out, with a few days of visible recovery attached to each one and sun protection running underneath the whole period. That is the real cost, and it is worth pricing before the first session rather than after the fifth.
The sessions and the gaps
A course usually runs to several sessions spaced some weeks apart — often four to six weeks, though the interval is decided by how your skin is responding rather than by a standard. The gaps are the treatment, not the delay between treatments: the skin needs to complete its response before it is injured again. A plan that shortens them to produce a faster result is adding risk without adding change.
The recovery days attached to each session
One day of obvious redness immediately after, which falls on the day after the appointment rather than the day of it. A second and third day of flaking or rough texture. Skin that looks normal under make-up within a week. Multiply that by the number of sessions in the course and it becomes the largest single cost of this treatment in practical terms: not the appointments, but the days around them.
The part that continues afterwards
Everything this treatment produces fades over time, so a maintenance interval is part of the honest description of the plan rather than an upsell at the end. Some patients choose occasional sessions to hold what they have; some choose to stop and accept the drift. Both are legitimate, and the difference between them is a decision rather than a default. What is not legitimate is a course described as having an end point when nothing about the treatment is permanent.
The reviews, and the sun protection
A review point sits after the early sessions, where the photographs are compared and the plan is confirmed, changed or stopped. Alongside the reviews sits the instruction that does not appear on any appointment list: sun protection, every day, for the duration. Skin that has recently been treated is more sensitive to the sun than skin that has not, and the pigment risk lives on the other side of that discipline. It is the part of the plan patients most often drop, and the part most likely to decide the outcome.
Three ways the calendar is underestimated
- The appointments are planned for and the recovery days around them are not, so the work and social cost arrives as a surprise.
- The course is treated as the whole plan, with nothing said about the maintenance interval that follows it.
- Sessions are compressed to fit a deadline — a wedding, a holiday — which shortens the recovery the skin needs between them.
Ask for the anticipated number of sessions, the interval, the review point and the maintenance interval in writing before you start. A plan that cannot be written down is a plan that has not been made.
Frequently asked questions
How long does a full course take from start to finish?
Months rather than weeks. Sessions are usually spaced some weeks apart so that the skin can complete its response before it is treated again, and the review point sits after the early sessions rather than at the end. Adding it up honestly: a course occupies the better part of a year of your calendar, even though each individual appointment is short.
Do I have to keep going after the course ends?
No, and the honest framing is that a maintenance interval is a separate plan rather than the continuation of the course. Everything the treatment produces fades over time, so some patients choose occasional sessions and some choose to stop. Neither is wrong, and both are better decided in advance rather than drifting into.
What if I miss a session?
It usually means the plan extends rather than fails. The intervals exist because the skin needs to recover, so a longer gap is rarely harmful; a shorter one is the problem. Tell the team rather than compressing the next two appointments to catch up, which is the mistake that turns a missed session into a course that is being rushed.
Risks & Limitations
- Response varies between people and between areas of the same face, and the session count is decided as treatment continues.
- Pigment change can occur in either direction, and the risk is higher in skin that darkens after injury.
- A cold-sore outbreak, infection, bruising or a granuloma can occur, and poor technique or a reused cartridge raises the risk.
- Treating the same area too often or too deeply can worsen texture rather than improve it. No result can be guaranteed.
When to Seek Care
- Spreading redness, increasing pain, fever or discharge after a session — contact the treating team promptly.
- Blistering, a burn-like reaction or a colour change that is spreading rather than settling.
- A mark that is new, changing, bleeding or asymmetrical — assessed as a diagnosis before any treatment.
- Difficulty breathing, chest pain, or a rapidly spreading skin infection — seek emergency care immediately.
