What to expect
- A consultation and any required patch test come before the first treatment.
- You wear protective goggles. The practitioner works across the shaved area with the laser, checking your comfort.
How it feels
Quick hot pinpricks or elastic-band snaps, often with cooling. Some areas are more sensitive.
Downtime
Redness and small swellings around hairs often settle within 1–3 days. Work is usually possible, though heat and friction can feel uncomfortable. Blisters or worsening pain need clinic advice.
Results
When you might see a change. Treated hairs shed over the following weeks. Judge reduced regrowth across the course.
How long it might last. Reduction may last months or longer; regrowth and maintenance needs vary, particularly with hormonal facial hair.
How often?
Multiple sessions are usual, often 4–6 weeks apart initially, with timing changed for the body area and growth cycle. Maintenance treats returning hair rather than following a fixed lifelong schedule.
Before your appointment
- Confirm a patch test and shaving instructions in advance.
- Avoid tanning; tell the practitioner about medicines and recent sun exposure. Ask when to stop waxing or plucking.
Aftercare
- Protect the area from sunlight and avoid rubbing irritated skin.
- Use the clinic’s cooling and skincare advice; allow hairs to shed without picking.
Is it right for everyone?
White, grey and very light hair responds poorly. Tanned skin, infection and light-sensitising medicines may delay treatment. Ask about experience treating your skin tone.
Common reasons people book
- Less frequent shaving
- Unwanted darker hair
What your practitioner will confirm
Laser wavelength, settings and patch-testing depend on skin and hair. IPL is a different technology and should be named accurately.
Treatment details are a general guide. Your practitioner will confirm what is suitable for you, the exact treatment plan and aftercare.
