The Science Behind Laser Hair Removal: How Does It Actually Work?

Laser hair removal offers a proactive approach to managing unwanted hair. At Aesthetics Now, we understand that each of our patients in Markham and Toronto, Ontario, is looking for something a little different. If one of your aesthetic concerns is unwanted hair, our laser treatments can help.

To help you determine if laser hair removal is the right choice for you, we will take a closer look at the science behind this treatment. You will be under the care of Dr. Monique Mazzuca and other experienced medical professionals who are committed to helping you understand our treatments so you can make an informed decision about your personal aesthetics.

What Is Laser Hair Removal?

Laser hair removal is a medical treatment that uses concentrated light to remove unwanted hair. During the process, a laser emits a light absorbed by the pigment in the hair. This light energy is converted to heat, damaging the hair follicles that produce hairs and inhibiting or delaying future hair growth.

Why Laser Hair Removal?

Compared to other hair removal methods, laser hair removal results are more efficient and long-lasting. While methods like shaving, waxing, and plucking offer temporary solutions, laser hair removal targets hair at the root, reducing hair regrowth significantly over time. It’s a preferred method for those seeking a more permanent and less maintenance-intensive solution.

Where Can Laser Hair Removal Be Used?

Laser hair removal is versatile and suitable for almost any part of the body, including the face, legs, arms, underarms, and back. Bikini laser hair removal is a popular choice, offering a low-maintenance and effective way to remove hair in this sensitive area without the pain of waxing or the irritation of razor burn. 

The Science of Laser Hair Removal

Understanding the Laser Device

Hair reduction laser devices are at the heart of this treatment. These devices emit a specific wavelength of light, designed to target hair follicles selectively. The precision of the laser allows for targeted treatment, minimizing impact on surrounding skin and maximizing efficacy in hair reduction.

How Lasers Target Hair Follicles

The process of laser hair removal involves the laser’s light being absorbed by the pigment in hair follicles. This absorption heats the follicle, effectively damaging it and hindering its ability to regrow hair. Because the laser focuses on melanin that is present in the deeper layers of the skin, the treatment is able to keep the surface of the skin from being affected by the laser’s energy. The best devices can be adjusted for different skin tones and hair types.

Phases of Hair Growth and Laser Timing

Effective laser hair removal treatment requires understanding the hair growth cycle. Your follicles aren’t all growing hair at the same time. Because lasers need to be able to target the melanin in hair that is in the active stage of growth, these devices can’t target all of your unwanted hair at once. We need to time our sessions based on when your follicles are actively growing hair, and we need to set up more than one treatment to be able to target all of the hairs eventually. Timing and patience are both important as we work to optimize results and efficiency.

What Can Influence the Effectiveness of Your Treatment?

Skin Type, Hair Color, and Hair Texture

The effectiveness of laser hair removal can be influenced by skin type, hair color, and texture. Darker hair, which has more melanin, can sometimes respond better to the treatment. It can sometimes be more difficult to treat blond or white hairs, and sometimes a greater contrast between skin and hair color can make a difference. However, we are able to treat a wider variety of skin and hair tones than before with our device. 

Laser Type and Technician Expertise

The type of laser used and the expertise of the technician are important factors in professional laser hair removal. At Aesthetics Now, we use the Cutera ND: YAG laser, which is known for its adaptability to different skin types and hair colors, enhancing treatment effectiveness. We are also experienced in treating unwanted hair and know how to time our treatments perfectly for the best effects. 

Environment and Lifestyle Factors

External factors such as environment and lifestyle can impact the results of a laser hair removal service. Sun exposure, for instance, can affect skin sensitivity and the individual’s response to the treatment. We will guide you in the right pre-treatment steps, such as avoiding tanning the skin before the treatment, to help you get the best results.

Adherence to Your Treatment Plan

The success of your laser hair removal treatment significantly depends on following the recommended treatment plan. Consistency in attending sessions as scheduled and following pre- and post-treatment care instructions can help you achieve the desired outcomes.

What to Expect From Your First Laser Hair Removal Treatment

In your first professional laser hair removal session, expect a consultation to discuss your medical history and treatment expectations. The targeted area will be cleaned, and you might receive a topical anesthetic. The hair will be shaved in the area if you haven’t already shaved. The device will be placed on small sections of your skin at a time, and each flash of laser light will target the hair follicles in that particular area.

You may feel some discomfort, akin to a rubber band snapping against the skin. The duration of treatment depends on the size of the area that we are treating. Post-treatment, slight redness or swelling is normal. You’ll be advised on aftercare, such as avoiding sun exposure and using specific skincare products. The first session sets the stage for your hair removal journey, with follow-up treatments scheduled as recommended.
