A little preparation makes laser hair removal safer, more comfortable and more effective. The good news is that the steps are simple — you just need to know them in advance.
Here is exactly how to prep your skin, from the weeks before to the day of your appointment.
In the weeks before
- Avoid sun and tanning for 4–6 weeks, and wear SPF daily.
- Stop waxing and plucking — the laser needs the follicle intact.
- Skip self-tanner for at least a week beforehand.
- Pause retinoids and strong exfoliants a few days before.
- Disclose medications that may affect your skin’s sensitivity.
Why you shouldn’t wax or pluck
This is the step people get wrong most often. Shaving is fine — encouraged, even — because it removes surface hair while leaving the follicle in place.
Waxing and plucking, on the other hand, pull the hair out by the root. Since the laser targets that root, removing it means there is nothing to treat until new hair grows.
The day before and day of
- Shave the treatment area about a day before your appointment.
- Arrive with clean skin — no makeup, lotion, deodorant or sunscreen on the area.
- Wear comfortable clothing that allows easy access to the area.
- Let your technician know about any changes since your consultation.
What to avoid before treatment
- Sunbathing, tanning beds and self-tanner
- Waxing, plucking and epilating
- Retinol, salicylic acid and strong exfoliants right before
- Perfumed lotions or deodorant on the day
Good prep protects your skin and improves results. For more on laser hair removal and what to expect over time, Healthline is a reliable resource.
Why prep matters
Proper preparation reduces the risk of irritation, helps the laser work efficiently, and protects your skin’s tone. It genuinely affects both safety and results.

Ready, prepped and smooth
Prep is simple: protect from the sun, shave (don’t wax), keep skin clean and product-free, and tell us about medications. Do that, and you are set up for safe, effective treatment.

After your session: a quick recap
Prep does not end when the laser does — gentle aftercare protects your results. Right afterwards, mild redness or warmth is normal and usually settles within hours.
For the next day or two, skip the gym, hot tubs, saunas and direct sun, and keep the area cool and moisturised. Apply a broad-spectrum SPF daily.
Between sessions, continue to shave rather than wax, and protect the area from the sun. These habits carry your good prep through to great results.

Why shaving (not waxing) is the golden rule
If you remember one thing about prep, make it this: shave, do not wax. Shaving clears surface hair while leaving the follicle intact for the laser to target.
Waxing, plucking and epilating remove the root entirely, so there is nothing for the laser to act on until new hair grows — which can set your progress back.
Shaving a day before also reduces the chance of surface irritation during treatment. It is the simplest, highest-impact part of a smooth laser experience.
Your quick prep checklist
To recap, here is the simple version: avoid sun and self-tanner for several weeks, stop waxing and plucking, pause retinoids for a few days, and disclose any medications.
Then shave about a day before, and arrive with clean, product-free skin on the treatment area. That is genuinely all it takes.
Follow this and your sessions will be safer, smoother and more effective. Next, see how many sessions you will need to plan your full course.
Small steps, big difference
None of these preparation steps are difficult, but together they make a real difference to how safe and effective your treatment is.
Skipping them — turning up with a fresh tan, waxed skin, or active retinol on board — can mean a less effective session or unnecessary irritation, and may even mean rescheduling.
A few minutes of preparation protects your skin and your results, so it is always worth getting right. When in doubt, just ask our team what to do before your visit — we are always happy to walk you through the steps so you arrive fully prepared and confident.
