Booking your first laser session can feel intimidating. You've read mixed things online, you're not sure if it'll hurt, you might be a little shy about the area you're treating, and you don't know what actually happens once the door closes. That's normal — almost every first-timer who walks into Luma feels a version of it.
So here's the honest, no-fluff guide we'd want a friend to read before her first appointment. What the room looks like, what we do, what it feels like, how to prep, and what your skin will be doing for the next 24 hours.
When you arrive: the first 10 minutes
You walk in, we offer you water, and you fill out a short intake form — medical history, medications, recent sun exposure. Nothing invasive. Three minutes, tops.
Then your esthetician does a quick skin assessment and, on a brand-new client, a small test patch — one or two pulses on a discreet spot — to see how your skin responds before we treat the full area. It's the most boring (and most important) part of the visit.
Who's in the room
Just you and one esthetician. The door is locked, the lights are low, and Luma is a private studio — no walking through a waiting room half-dressed. If you've been to a chain clinic and felt rushed or exposed, this will feel like a different planet.
What the room actually looks like
Think calm, not clinical. A treatment chair that reclines like a spa bed. Soft lighting. The Candela GentleMax Pro Plus laser sits on a slim white cart next to you — quieter than most people expect. You'll wear protective eyewear (it's required for everyone, including us), and the cooling spray on the laser handpiece does most of the comfort work.
What does it actually feel like?
The most honest description we have, after thousands of sessions: a warm rubber-band snap, followed instantly by a puff of cooling air. Not nothing — but very manageable. Most clients are surprised by how much less it hurts than waxing.
Different areas feel different:
- Underarms: quick and easy. Most people barely flinch.
- Brazilian: more sensitive, especially the inner labia and tailbone. But it's fast — usually 20 minutes, and the discomfort comes in 5-second bursts, not constant.
- Legs: mostly painless, with a few tender spots near the ankles and inner thighs.
- Face (upper lip, chin): a little zingy because the skin is thin, but over in minutes.
If something genuinely hurts, tell us. We adjust the fluence and cooling in real time. You're never "stuck" tolerating a setting that doesn't feel right.
How long does the session actually take?
- Underarms: 10–15 minutes in the chair.
- Brazilian: around 20 minutes.
- Upper lip / chin: 5–10 minutes.
- Full legs: about 45 minutes.
- Full body: 90 minutes to 2 hours, depending on coverage.
Add 10 minutes on either side for changing, consult, and aftercare, and you have a realistic block to plan around.
How do I prep my skin?
Prep is genuinely simple, but skipping it is the #1 reason people don't get the results they paid for.
4 weeks before
- No waxing, threading, plucking, or epilating. The laser needs the hair root to be intact and connected to the follicle — pulling it out defeats everything.
- Shaving is fine. Encouraged, even.
2 weeks before
- No intentional sun exposure, tanning beds, or fake tan on the treatment area.
- Pause any new actives — don't introduce a new retinol the week before your laser.
The night before
- Shave the area cleanly with a fresh razor, with the grain. The hair needs to be at skin level — not above, not waxed out.
Day of
- Arrive with clean, dry skin. No lotions, oils, deodorant, perfume, or makeup on the area.
- Hydrate well. Skipping caffeine that morning genuinely helps with comfort — your nervous system is calmer.
- Eat something light an hour before. Showing up on an empty stomach can make you feel woozy, especially for longer sessions.
What should I wear?
Comfortable, loose, easy to take off and put back on. Some specifics that help:
- Legs: a dress or wide-leg pants. Not skinny jeans you have to peel back on over warm skin.
- Bikini / Brazilian: loose underwear or none — we provide a disposable thong if you'd like.
- Underarms: a tank top or a shirt that opens at the front.
- Face: just come bare-faced, and bring SPF for the walk home.
The Brazilian (or any intimate area), specifically
This is the question we get most in DMs. You can keep your underwear on if you want — we drape and uncover one section at a time. Periods are usually fine (tampon or cup). And your esthetician has seen every body, every hair pattern, every shape — there is genuinely nothing surprising about yours.
If you're nervous, say so. We'll go slower, talk you through every step, and you can stop at any moment.
Will I see results after the first session?
A little. Don't expect dramatic. Here's what's actually happening: the laser disables hair follicles that are currently in their active growth phase, which at any given time is only about 20–30% of your follicles. The rest are dormant. That's the entire reason you need a series.
What most clients see after session one:
- About 1–2 weeks later, treated hairs start to "shed" — they look like they're growing, but they're actually pushing out as the follicle releases them. A gentle scrub helps.
- After the shed, that area is noticeably smoother for a few weeks.
- Then a new batch of dormant hairs surfaces, ready for session two.
By session 2 or 3, most clients say it's the first time they can see a real, noticeable change. By session 6, the difference is dramatic. For more on this, see our guide on how many sessions you actually need.
Is it safe for my skin tone?
Yes — including darker skin tones. The Candela GentleMax Pro Plus is a dual-wavelength system, which means it has both an Alexandrite laser (for lighter skin) and an Nd:YAG laser specifically designed for medium to deep skin tones. Your esthetician selects the right wavelength and settings for your specific skin during the consultation.
If you've been told before that laser isn't safe for you, it might have been an older machine. We wrote a full breakdown on laser hair removal for darker skin tones if you want the deep dive.
What happens after the session
Expect mild redness and a little warmth, similar to a light sunburn, for a few hours. Some people get tiny bumps around the follicles for 24 hours — this is the skin reacting, not breaking out.
- No hot showers, sauna, steam, or intense workouts for 24 hours.
- SPF 30+ on any treated area exposed to sun — this is non-negotiable for the next two weeks.
- Skip retinoids and exfoliating acids on the area for 5–7 days.
- Between sessions, only shave. Never wax, thread, or pluck.
For the full breakdown, see our pre & post-treatment care guide.
Day-of-session checklist
- Area is freshly shaved (night before, with the grain).
- No deodorant, lotion, oil, perfume, or makeup on the area.
- Comfortable, loose clothing — easy access to the treatment zone.
- Light meal an hour before. Don't arrive starving.
- Hydrated. Skip the second espresso if you can.
- Arrive 10 minutes early to settle, fill out the form, breathe.
- Bring SPF for the walk home if your face or arms were treated.
Still not sure? Start with a free consultation
If you'd rather meet the space, meet your esthetician, and ask every question before you commit — that's exactly what the consultation is for. It's free, there's no pressure to book, and you can do a tiny test pulse on your forearm so you know exactly how the laser feels before any real session.

However you start — you're in good hands.
