In short. What an erbium course costs in time rather than money: the assessment, any test-spot wait, the treatment day, the raw days at home, and the pink weeks.
Key points
- Count the assessment, any test-spot wait, the priming period, the treatment day, the raw days at home, the pink weeks when the sun has to be avoided, and the review appointments.
- That total, not the fee, is what most people are actually deciding about, and it is the number a plan should state before you agree.
This site does not quote prices, and the cost that decides most plans is not money anyway. It is time: appointments, a test-spot wait, the treatment day, the days at home while the surface is open, the weeks of limited sun, and the gap before a second set of passes is considered.
Before the treatment
An assessment appointment comes first, and it may be followed by a test spot observed over a period before the full plan is fixed. Skin is often primed for several weeks beforehand, which costs nothing in clinic time but does mean the treatment cannot be brought forward on a whim. Skincare that irritates the skin is usually stopped for a period first.
The treatment day and the raw days
Treatment itself takes an afternoon and is the easiest part, because it happens under anaesthesia. The days that follow are the expensive ones. The surface is open for roughly four to seven days — raw, weeping and socially impossible — and most people plan to be away from being seen for that whole stretch plus a margin. Work that involves meeting people, travel and photographs are all out.
Adding up the days honestly
Count the assessment, any test-spot wait, the priming period, the treatment day, the raw days at home, the pink weeks when the sun has to be avoided, and the review appointments. That total, not the fee, is what most people are actually deciding about, and it is the number a plan should state before you agree.
The pink weeks
Once the surface has closed the skin is intact but red, and the redness is measured in weeks. It is usually shorter than after a heat-heavier ablation, which is one reason this variant is chosen, but it still restricts sun exposure, swimming, saunas and strenuous exercise for longer than most people expect. Those weeks are a real cost even though they are not days off work.
Reviews and a second set of passes
A review follows treatment, and the result is judged in months rather than weeks, because a shallower change declares itself slowly. If a second set of passes is planned, it is usually separated from the first by an interval long enough for the skin to settle and for the first result to be visible. A series spread across a year is a different commitment from a single appointment, and it belongs in your calendar before you start.
Be cautious when a plan
- Quotes a number of sessions before examining your skin or observing a test spot.
- Describes the recovery as a few days without counting the pink weeks after it.
- Offers a discount that expires, which prices the decision rather than the treatment.
Time is the honest currency of this treatment. A plan that sets out the days it takes, including the weeks that are not days off, is a plan you can decide about. One that talks only about the appointment is not.
Frequently asked questions
How far apart are erbium sessions usually spaced?
It depends on the plan, but a second set of passes is usually separated from the first by a long interval rather than a short one, often several months. The skin has to settle, the redness has to fade enough to judge the change, and the first result has to be visible before anyone decides whether more is worth doing. Some plans are a single treatment rather than a series.
How many appointments does an erbium course involve in total?
At minimum an assessment, the treatment day and a review afterwards. A staged plan adds a test-spot visit and its observation period before treatment, and a series adds a treatment day and a review for each session. Some plans also include priming appointments beforehand. The count belongs in the plan rather than being discovered booking by booking.
What has to be arranged before the treatment day?
Someone to bring you home, someone with you for the first two days at least, food that needs no preparation, and the clinic's out-of-hours contact kept somewhere you can find it. Anything you have been told to stop beforehand, including irritating skincare and some medicines, and a clear stretch of days with nothing that requires being seen.
Risks & Limitations
- The surface is left open rather than sealed by heat, so pinpoint bleeding and oozing on the treatment day are expected; bleeding continuing beyond the first day or two needs review.
- Infection of open skin is the risk of the first days, which is why antiviral cover is ordinarily prescribed; increasing pain after the third day, spreading redness or fever needs same-day review.
- Pigment can shift in either direction: darkening is more common, more stubborn in darker skin, and can take months to settle, while lightening is uncommon and may not recover.
- A visible border can remain where treated skin meets untreated skin, and it is the one change on this list that time does not reliably soften.
- Scarring is uncommon but real, and no lower on a gentler plan; risk rises after infection, after treatment too deep for the skin, on thin skin, and in people who form raised scars.
- Each pass removes tissue that does not come back, so the number of times one area can be treated has a ceiling, and less residual heat means less tightening and less change in deep folds.
When to Seek Care
- Pain that increases after the third day instead of easing, or one patch much hotter and more swollen than the rest.
- Fever, spreading redness, or discharge from the treated area.
- Bleeding that continues beyond the first day or two, or that restarts after it had settled.
- A cold sore erupting across healing skin, which should be reported the same day.
- Blistering, dusky or grey patches, or a sore that is not crusting like the rest of the face.
