How to Prep for Laser Hair Removal

If you’re tired of the constant battle with razors, waxing strips and tweezers, laser hair removal might be your perfect solution. Laser hair removal is one of the most effective hair removal methods for permanent hair removal, especially for those areas like the upper lip, underarms, legs and bikini line where unwanted hair is a constant nuisance. But before you book your laser hair removal appointment, there are several important steps you need to follow to ensure the best results and minimize side effects. Let’s dive into how to properly prep for your laser hair removal treatment.

Understand How Laser Hair Removal Works

Before you jump in, it’s good to understand how the laser hair removal procedure works. The laser targets the hair follicles beneath your skin by emitting laser energy that is absorbed by the melanin (the pigment in your hair). This process damages the hair follicles, hindering hair growth over time. However, because lasers target dark hair, they can be less effective on light or gray hair. It’s also important to note that the laser is most effective during the hair’s growth cycle, which is why multiple sessions are necessary.

What to Avoid Before Your Laser Hair Removal Session

In the weeks leading up to your laser hair removal treatment, there are a few things you should steer clear of to ensure your skin is in the best condition for the procedure.

1. No Waxing, Tweezing or Plucking

Unlike other hair removal methods, you need the hair follicles intact for the laser to work. Waxing, tweezing or plucking your hair removes the hair from the root, which makes it difficult for the laser to target the hair follicles. So, put down the wax strips and tweezers for at least four weeks before your appointment. Shaving, however, is fine since it only removes hair from the skin’s surface.

2. Avoid Tanning and Tanning Beds

Tanning or using tanning beds can increase your risk of skin irritation during and after your laser hair removal procedure. Sun exposure can make your skin more sensitive to the laser, leading to unwanted side effects like blistering or sunburn in the treated area. Make sure to avoid tanning, either from the sun or self-tanners, for at least two weeks before your session.

3. Stay Away From Retinol and Topical Creams

Certain skincare products, especially those containing retinol, benzoyl peroxide and bleaching agents, can increase photosensitivity, making your skin more prone to irritation from the laser. Discontinue using these topical treatments at least five days before your laser hair removal session.

How to Prep Your Skin Before Your Laser Hair Removal Appointment

Now that you know what to avoid, let’s go over how to get your skin ready for the big day.

1. Exfoliate Your Skin

Gently exfoliate the treatment area a few days before your session to remove any dead skin cells that could interfere with the laser. This will ensure the laser can penetrate the skin’s surface and reach the hair follicles more effectively.

2. Shave the Treatment Area

While plucking, waxing and tweezing are off-limits, shaving is a must. Shaving removes the hair above the skin’s surface without affecting the hair follicles. This allows the laser to focus on the root of the hair during your session. Make sure to shave the treatment area 24 to 48 hours before your laser hair removal appointment to avoid irritation.

3. Arrive With Clean Skin

Before your session, make sure the treatment area is clean and free of lotions, creams, deodorant or makeup. These products can interfere with the laser’s ability to target the hair. Wash with a gentle cleanser, and avoid any harsh skincare ingredients.

4. Skip Moisturizers and Self-Tanners

While keeping your skin hydrated with moisturizers is generally a great idea, it’s best to skip them on the day of your appointment. Also, if you use self-tanners, you’ll want to stop using them at least two weeks before your session, as tanned skin can make it harder for the laser to effectively target the melanin in your hair.

What to Discuss With Your Provider

Before your treatment, you’ll have a consultation to create a treatment plan. This is the perfect time to discuss any medications you’re taking and your medical history. For example, some medications can increase photosensitivity, making you more prone to side effects like blistering. Also, certain conditions or skin types may require adjustments to the laser settings to avoid complications. For people with darker skin, different laser technologies may be used to prevent skin damage.

Protect Your Skin After the Treatment

After your laser hair removal session, proper post-care is essential for keeping your skin healthy and avoiding irritation.

1. Apply Sunscreen

Since your skin will be more sensitive post-treatment, protecting it from the sun is essential. Use a broad-spectrum SPF 30 or higher, especially if the treated area is exposed to the sun. This reduces the risk of pigment changes and helps your skin heal without issues.

2. Avoid Harsh Products

After your session, avoid skincare products that contain harsh chemicals like benzoyl peroxide, retinoids or bleaching agents. These can irritate the treated area, slowing the healing process and increasing the risk of skin irritation.

3. Stay Away From Heat

Your skin will be sensitive, so avoid activities that expose your skin to excessive heat, such as hot showers, saunas or tanning beds. These can increase irritation and prolong the healing process.

4. Keep the Area Moisturized

While you should skip moisturizers before your treatment, after your session, it’s a good idea to use gentle, hydrating lotions to soothe the skin. Look for products that are free of fragrances and alcohol to avoid irritation.

5. Avoid Certain Activities

After your treatment, avoid strenuous activities that cause sweating, as this can irritate the treated area. It’s a good idea to skip the gym and hot yoga classes for a couple of days.

How Many Sessions Will You Need?

Laser hair removal requires multiple sessions to achieve the best results. Hair grows in cycles, and the laser is most effective during the active growth cycle. Most people need between 6 to 8 sessions spaced several weeks apart to see a significant reduction in unwanted hair.

Will Laser Hair Removal Interrupt Other Skin Treatments?

Laser hair removal can be safely combined with many other skincare procedures, but timing is important. If you’re undergoing acne treatments like topical creams or oral medications, it’s best to pause them temporarily, as they can increase skin sensitivity. Similarly, you should avoid scheduling laser sessions too close to microneedling, or injectables like Botox, to prevent irritation in the treatment area. Have no fear: a consultation with your provider will help you create a plan that ensures your skin heals properly between treatments.

Final Thoughts

Prepping for laser hair removal is essential for getting the best results. From avoiding sun exposure to making sure your skin is free from lotions and creams, following these steps will help ensure a smooth experience with minimal side effects. Whether you’re treating your underarms, legs or upper lip, taking care of your skin before and after each session will help you get the most out of your laser hair removal treatment. If you have any concerns, be sure to discuss them with your provider at your consultation.
