In short. Maintenance between courses is the plan for the period after a course of skin treatment ends, when the skin continues to behave as living tissue. It holds an improvement rather than building a new one, and its interval is judged by the skin and by the finding being maintained.
Key points
- A course ends on a day; the skin does not, so the period between courses belongs in the plan.
- Results fade because vessels, pigment cells and collagen continue to behave as living structures.
- Maintenance holds an improvement at longer intervals rather than building a new one.
- Sun protection, an intact barrier and a consistent routine do most of the daily work.
- Adding treatments before the skin settles delays the result and raises irritation risk.
What maintenance is actually for
A course of skin treatment ends on a particular day, and the skin does not. Maintenance is the plan for the period afterwards, and it decides how much of the improvement is still visible a year later. It holds an improvement rather than building a new one: repeat sessions at longer intervals, and a routine that is continued rather than abandoned, keep the ground that was gained.
Why does a result fade when the treatment worked?
Each treatment works on a structure that is alive and continues to behave. Vessels that were closed can widen again, pigment cells that were moderated stay in place and respond to sun, and the collagen scaffold continues to turn over at its own rate. None of that is a failure. It is the skin doing what skin does, and it is why a result is described in months rather than in years.
How is the interval between sessions decided?
The interval is judged by how your skin behaves and by the finding being maintained, so it differs between people and between treatments. It usually lengthens once a stable state is reached. Where a finding is stable and the improvement matters to you, repeat sessions at longer intervals hold it. Where it is not, stopping is a reasonable decision rather than a failure of the plan.
What happens between appointments?
Three things decide whether the next course builds on the last: protection from sun, a barrier that stays intact, and a routine that is consistent without being aggressive. Sun exposure is the single largest reason a pigment result is lost, and a harsh routine that irritates the skin works against everything the course achieved. This part of the plan is unglamorous and it is the part that does the most work.
Why more treatment is not the answer
Adding treatments to skin that has just been treated, stacking active products, or starting a second course before the skin has settled does not accelerate the result; it delays it and increases the risk of irritation. Where a complaint has not changed after a reasonable course, the answer is a reassessment of the structure rather than more of the same.
What should a plan say about stopping?
Any honest plan states whether a result is held by maintenance, how long an improvement is expected to last without it, and what the skin returns to. If that question has no answer, the plan has a gap in it rather than a guarantee.
| Element of the plan | What it does | Timing | What it depends on |
|---|---|---|---|
| Repeat sessions | Hold an improvement rather than build a new one | At longer intervals | How the skin behaves and the finding being maintained |
| Sun protection | Limits the largest reason a pigment result is lost | Daily | Exposure and the finding |
| Barrier care | Keeps the barrier intact between appointments | Daily | The barrier staying intact |
| Consistent routine | Keeps the ground gained without irritating the skin | Daily | A routine that is not aggressive |
| Stopping | Returns the skin to its own trajectory | A decision rather than a failure | Whether the finding is stable |
| Adding treatments early | Delays the result and increases irritation risk | Not before the skin has settled | Whether the skin has settled |
When to contact the team
A treated area that becomes increasingly painful, red, hot and swollen may be an infection and needs review. A blister, crust or sore that was not expected and is not settling is reviewed rather than treated again. A mole or lesion in a treated area that changes is assessed rather than treated again.

Frequently asked questions
Does a result fade because the treatment stopped working?
No. It fades because the skin continues to behave as skin does. Vessels that were closed can reopen, pigment cells that were moderated remain in place and respond again to sun, and the scaffold that was stimulated continues to turn over as it always did. A result is an improvement on the skin's own trajectory rather than a new fixed state, and maintenance is the difference between keeping that improvement and losing it.
Do I need to keep having treatments forever?
No, and a plan that assumes you do is worth questioning. Maintenance is a choice with a purpose: where a finding is stable and the improvement matters to you, repeat sessions at a longer interval keep it. Where it is not, stopping is reasonable, and the skin returns to its own trajectory rather than becoming worse than before. The honest plan states what happens if you stop.
Is it worth having maintenance if I cannot keep it up?
That is a fair question to ask before a course rather than after one, and the answer belongs in the plan. A course followed by nothing may still leave a change that lasts months, which is a reasonable outcome for some people. What is not reasonable is being told that a result lasts, because the skin has not read the plan, and carries on as it was.
Risks & Limitations
- Every skin treatment carries risk, and no result can be promised.
- Pigment often returns after treatment, especially after sun exposure, because the cells that produce it remain in place.
- Skin that marks easily after injury can darken or lighten after a treatment, which is why a test spot is used to judge the risk.
- Results are judged over months rather than weeks, and maintenance is often needed to hold them.
When to Seek Care
- A mole that is changing in size, shape or colour, or one that bleeds, itches or crusts.
- A spot, sore or crusted patch that has not healed over a few weeks.
- A rash with fever, joint pain, mouth ulcers or blistering, or one that involves the eyes or mouth.
- A treated area that becomes increasingly painful, red, hot and swollen, which may be an infection.
