So, you’re finally ready to ditch the razor and book that laser hair removal appointment? Awesome choice. But wait—before you jump in, there are a few things you absolutely need to do. Prepping right isn’t just a nice-to-have—it’s essential for getting the best, longest-lasting results.

Let’s break it down, step by step. Oh, and if you’re thinking of becoming a pro yourself, we’ll also show you how to get trained at the best Laser Hair Removal Course San Antonio has to offer, at Advanced Laser Institute of San Antonio.

Why Prepping for Laser Hair Removal Matters

Skipping the prep can mean uneven results, increased sensitivity, or even skin damage. Laser hair removal is a process that works best when your skin is calm, hydrated, and hair is shaved (not waxed!). The better your prep, the smoother the session.

Understanding the Basics

How Laser Hair Removal Works

Lasers target the pigment (melanin) in your hair follicles, zapping them to stop future growth. Multiple sessions are needed because hair grows in cycles, and lasers only target active growth stages.

Why Skin & Hair Type Matter

People with lighter skin and darker hair typically see faster results. But thanks to modern tech, it’s effective for many skin tones—it just might require customized settings.

Timeline: Your 4-Week Preparation Plan

Here’s your week-by-week countdown to your laser session:

4 Weeks Before Treatment

  • Stop waxing, plucking, or using depilatory creams. You need hair follicles intact for the laser to do its job.
  • Limit sun exposure—tanned skin can lead to complications.

2 Weeks Before Treatment

  • Avoid spray tans or tanning beds.
  • Start using sunscreen (SPF 30+ daily in the treatment area).
  • Switch to gentle skincare.

1 Week Before Treatment

  • Avoid exfoliating products (like glycolic acid or retinol).
  • No antibiotics or photosensitizing meds unless cleared by your provider.

24 Hours Before Treatment

  • Shave the treatment area. Yes, shave—not wax or tweeze.
  • Skip lotions, creams, deodorants, or perfumes.

Skincare Tips to Follow

Avoid Tanning and Sun Exposure

Sunburnt or recently tanned skin is more sensitive and risks burning or pigmentation. Use broad-spectrum sunscreen daily!

Don’t Use Certain Skincare Products

A few days before treatment, avoid retinol, AHAs, BHAs, and anything containing benzoyl peroxide or salicylic acid.

Hair Removal Methods to Avoid

Skip Waxing, Tweezing, and Depilatories

These methods remove the hair from the root, which means the laser has nothing to target. This is a big no-no.

What About Shaving?

Shaving is the only approved method because it leaves the root intact but clears surface hair that could burn during treatment.

Medications and Medical Conditions

Inform Your Technician

Be honest about your health history, including any skin conditions or medications. It helps your technician adjust settings to avoid reactions.

Medications That Can Interfere

Photosensitizing medications (like Accutane or antibiotics) can increase the risk of burns or pigmentation. Always disclose what you’re taking.

What to Wear and Bring on the Day

Comfortable Clothing is Key

Loose clothing makes access easier and avoids irritating treated areas post-session. Think cotton, not spandex.

Skip Makeup and Lotions

If your face is being treated, come in clean-faced. Lotions and deodorants can interfere with the laser.

What to Expect at Your First Appointment

Patch Testing & Consultation

You’ll likely get a small test area zapped to check your skin’s response and adjust the laser settings accordingly.

Session Duration and Pain Level

Sessions vary by area—from 10 minutes (upper lip) to over an hour (full legs). Pain-wise? It feels like a rubber band snap. Tolerable, we promise.

FAQs

1. Can I shave right before my appointment? Yes! In fact, you should shave 24 hours before your session to protect your skin and help the laser do its job better.

2. What if I accidentally tanned before my session? Let your technician know. They may reschedule your appointment to avoid side effects like burns or hyperpigmentation.

3. Is it okay to apply deodorant before underarm laser treatment? Nope. Skip it for the day—it can react with the laser and irritate your skin.

4. Can I work out before or after the session? Avoid heavy sweating before and at least 24 hours after treatment. Heat and friction can irritate freshly treated skin.

5. Do I need to stop using skincare products like retinol? Yes, about 5–7 days before treatment. Retinoids can make your skin more sensitive and increase the risk of irritation.
