Laser Hair Removal
For those seeking long-term results, laser hair removal is a leading technique for eliminating unwanted body hair. This cosmetic procedure aims to remove unwanted hair for extended periods. In this article, we will explore how this technique works, its benefits, potential risks, and what you should know before undergoing it.
What is Laser Hair Removal?
Laser hair removal relies on a process called selective photothermolysis. The heat generated by the laser destroys skin cells containing a high amount of melanin pigment. Since dark hair contains a lot of melanin, it absorbs the heat more, transferring the heat to the hair follicles and destroying them, thus preventing hair regrowth.
Advantages and Benefits of Laser Hair Removal
Here are the advantages and benefits of using laser for hair removal:
Long-term Results
This method provides long-term results until the hair regrows, and over time, the hair grows back finer and thinner.
Time and Effort Saving
Other hair removal methods like shaving need to be repeated every few days. In contrast, laser hair removal requires several consecutive and regular sessions, followed by a single session every now and then to maintain the results. Additionally, this technique saves time, as small areas like the upper lip can be treated in one minute, while larger areas like the back or legs may take about an hour.
Long-term Cost Saving
Although the initial cost is high, laser hair removal can save money in the long run compared to traditional methods that require continuous purchase of products.
Treating Some Skin Issues
This technique helps treat some skin problems, such as reducing ingrown hairs and preventing folliculitis, a skin condition that causes inflammation of the hair follicles.
How Many Laser Hair Removal Sessions Are Needed?
The doctor determines the number of sessions required based on several factors, such as the area to be treated, hair density, skin color, and skin type. Typically, 2 to 6 laser hair removal sessions are needed. After the sessions, hair appearance usually decreases or disappears for months or even years. When it reappears, it is less dense, and a maintenance session can be done to preserve the achieved results.
Contraindications for Laser Hair Removal
Certain groups should avoid this technique, including:
- Pregnant women
- People taking certain medications, such as acne treatments
- Individuals with genital herpes or a high likelihood of oral herpes
- Those with skin cancer or a history of it
Pre-Laser Hair Removal Instructions
Here are some guidelines to follow before undergoing a laser session:
- Avoid direct sun exposure for at least 6 weeks before the session, as sun exposure reduces session effectiveness and increases the risk of complications post-session.
- Avoid blood-thinning medications and consult your doctor about other medications to stop before the sessions, such as anti-inflammatory drugs.
- Shave the hair from the target area a day or two before the session to ensure effective results.
Post-Laser Hair Removal Tips
Here are some post-session recommendations:
- Avoid direct sun exposure.
- Use cold compresses and skin moisturizers to reduce swelling and redness after the laser session.
Disadvantages and Side Effects of Laser Hair Removal
This technique is generally safe, but it may cause some side effects, such as:
- Mild pain during the session
- Swelling and redness of the skin
- Skin darkening
In rare cases, laser hair removal can cause burns or blisters, especially if the device is not used correctly.
Laser Hair Removal at Dr. Rana Gheith's Center
At Dr. Rana Gheith’s Center, we use Candela Gentle Pro laser devices that selectively target the hair follicle with intense pulses of light energy to thermally destroy it without damaging the surrounding tissue. The skin is protected by the Dynamic Cooling Device™ (DCD), which sprays the treated area with a cooling agent before each laser pulse. This system provides a cooling factor that is 50% more effective than contact or air cooling and can be adjusted according to individual needs to make the procedure as comfortable as possible.
