Laser Hair Removal: What to Expect Before, During, and After Treatment

By Dr. Debra Durst, MD – Founder, RevitalyzeMD

Laser hair removal has become one of the most popular solutions for unwanted hair, offering a long-lasting alternative to shaving, waxing, and plucking. If you’re considering this treatment, understanding the process from start to finish can help you feel confident and prepared. In this guide, we’ll walk you through what to expect before, during, and after your laser hair removal sessions, with a focus on safe, reliable treatments available at RevitalyzeMD.

Laser hair removal targets hair follicles with concentrated light energy. The laser penetrates the skin and is absorbed by the pigment in the hair, damaging the follicle to slow or prevent future growth.

Different hair colors and skin tones can affect results, which is why experienced professionals, like us, personalize treatments to each patient. Laser hair removal is most successful when performed by a trained provider who can safely adjust settings for optimal results while minimizing irritation.

Proper preparation supports the best outcomes and reduces the risk of side effects. Here’s what you should do before your session:

1. Avoid Sun Exposure

Protect your skin by avoiding tanning beds or direct sun exposure for at least two weeks before treatment. Sunburned or tanned skin can increase the risk of irritation.

2. Shaving vs. Waxing

Shave the treatment area 24–48 hours before your session. Avoid waxing, plucking, or using depilatory creams, as these remove the hair follicle that the laser needs to target.

3. Skin Care Prep

Skip lotions, creams, deodorants, and other products on the day of treatment. Clean, product-free skin allows the laser to work successfully.

4. Consultation and Patch Test

A preliminary consultation and patch test help determine your suitability for laser hair removal. This confirms we can safely treat your skin type and hair color.

Knowing what to expect can help reduce anxiety for first-timers:

Step-by-Step Experience

During treatment, you may feel a mild snapping or tingling sensation as the laser passes over the hair follicles. Many clinics use cooling devices or numbing gels to keep you comfortable.

Treatment Areas

Laser hair removal is versatile. Common areas include the legs, arms, underarms, bikini line, and face.

Duration of Sessions

The session length depends on the size of the treatment area. Small areas like the upper lip can take just a few minutes, while larger areas such as the legs may take an hour or more.

Safety Measures

Protective eyewear is provided, and our licensed professionals closely monitor the treatment to maintain your safety and comfort.

Post-treatment care is essential for smooth results and minimal side effects:

• Immediate Skin Care: You may notice redness, mild swelling, or sensitivity in the treated area. Applying cool compresses can reduce discomfort.
• Avoid Irritants: For several days, avoid sun exposure, hot showers, saunas, and harsh skincare products to allow your skin to heal.
• Hair Shedding and Regrowth: Treated hairs will gradually fall out over the following days or weeks. Multiple sessions are typically required to catch all hairs in their growth phase and achieve optimal results.
• Follow-Up Treatments: Most patients require 4–6 sessions spaced several weeks apart for lasting hair reduction. 

Laser hair removal works best on individuals with darker hair and lighter skin, although advances in technology allow for successful treatment across many skin tones.

During your consultation, we will assess your skin, hair type, medical history, and treatment goals to make sure you’re a good candidate. Certain medications or medical conditions may affect eligibility, so full disclosure is important.
