In short. How IPL results fade, what realistic maintenance intervals look like, and how to tell a plan from an open-ended package you keep paying for.
Key points
- Maintenance is best decided from how your own skin has behaved, not from a timetable fixed at the start.
- One or two sessions a year is a common starting point, but the honest position is that the interval should be set by what the photographs show.
- Be cautious of any arrangement in which you pay in advance for sessions you have not yet needed.
Nothing about this treatment is permanent, and the reason is simple: the skin keeps making pigment. A course clears a good part of what has accumulated, and then sun exposure, hormones and time begin to put it back. Maintenance is the honest word for what follows, and the decision worth making carefully is what maintenance should look like.
How the result fades
The change after a course usually holds through the following months, and then the mottling gradually returns, fastest in people who spend time outdoors and slowest in those who do not. Freckling tends to return with the first substantial sun exposure of the next summer. Redness from vessels behaves differently: closed vessels do not reopen, but the condition that produced them continues and new ones can form.
Two things slow the fade considerably, and neither of them is a device. Daily sun protection, used properly and reapplied, and a topical routine that supports the barrier and helps control pigment. A patient who does both often needs far fewer maintenance sessions than one who does neither.
A schedule sold in advance is a package
Maintenance is best decided from how your own skin has behaved, not from a timetable fixed at the start. One or two sessions a year is a common starting point, but the honest position is that the interval should be set by what the photographs show. Be cautious of any arrangement in which you pay in advance for sessions you have not yet needed.
When to stop
There is a point at which further sessions stop producing visible change. In practice it arrives when the pigment that remains is deeper, hormonal, or simply not the kind that responds to light. Recognising it is easier if the comparison is made from photographs rather than from memory, because memory is unreliable in both directions: patients who have done well underestimate the change, and patients who have not often see improvement that is not there.
Stopping is a legitimate outcome. The result at that point is what the treatment can do for your skin, and repeating it indefinitely adds cost and risk while producing a flatter return. It is entirely reasonable to ask for a review instead of another session.
Reassess rather than renew if
- Two consecutive maintenance sessions have produced no visible change in standardised photographs.
- You are offered a large prepaid block to be used at a fixed frequency regardless of how your skin looks.
- The pigment returning is darker, newly shaped, or in a different pattern from before — that should be examined rather than treated.
The right maintenance plan is small, occasional and responsive. If it has become an annual subscription you pay without asking whether it is still doing anything, it has stopped being a treatment plan and become a habit.
Frequently asked questions
How often do most people need maintenance?
One or two sessions a year is a common starting point, decided from how the skin has behaved rather than from a fixed timetable. Patients with consistent sun protection often need fewer.
Can I stop having IPL altogether?
Yes. The result fades gradually, and nothing is harmed by stopping. Maintenance is a choice about how much of the improvement you want to keep, not a commitment the treatment imposes on you.
Why do my freckles return every summer?
Because the tendency to freckle is inherited and sun exposure drives it. The treatment removes pigment that has accumulated; it does not stop the skin producing more of it.
Risks & Limitations
- Pigmented spots darken before they flake away; that darkening is expected and is not a burn — blistering, crusting or increasing pain is.
- Post-inflammatory hyperpigmentation is a real risk, is more common and more stubborn in darker skin, and can take months to settle.
- Burns and blistering occur, particularly on tanned skin, with settings chosen for the device rather than the skin, and where passes overlap the same area.
- Treated skin can occasionally lose pigment rather than gain it, leaving pale patches that are difficult to treat.
- Scarring is rare and usually follows a burn or an infection in treated skin; a tendency to raised scarring is assessed before treatment.
- No result is permanent. Pigment returns as the skin continues to produce it, and sun exposure is the main thing that decides how quickly.
- The treatment changes colour, not contour. It does not tighten, lift, fill or remove wrinkles.
- Eye protection is worn by everyone in the room, because the light can injure the eye.
- Individual response varies; no outcome can be guaranteed.
When to Seek Care
- Blistering, severe or increasing pain, or a wound that is weeping or crusting after a session.
- Skin in the treated area becoming markedly darker over the following weeks rather than fading, or developing pale patches.
- A cold sore, a spreading rash or a fever after treatment.
- Any pigmented spot that is new, changing in size, shape or colour, or that looks different from the others on your skin.
- Frequent severe flushing with other symptoms, which needs a medical assessment rather than a cosmetic plan.
