How Does Diode Laser Hair Removal Work?
- Diode Laser hair removal works on the principle called ‘selective photothermolysis’.
- This means that dermatologists match the specific wavelengths of light and pulse duration to that of the treatment tissue to obtain the maximal effect.
- Melanin is the colour pigment present in skin and hair that absorbs this radiation, acting as the target matter.
- The melanin in the hair follicles absorbs the intense heat of the laser.
- This damages the hair follicle, hence inhibiting future hair growth.
That is why the treatment works best on those with light skin (low melanin) and dark hair (higher melanin) as the melanin in the hair draws the radiation away from the skin.
Different lasers are effective for different hair and skin types.
Diode laser: Face Hair Removal Laser
Amongst the different lasers available, the diode laser has stood the test of time. There are many reasons for this, such as:
- Diode laser projects light within the visible to the infrared range (~810 nm) in order to target specific pigment cells.
- It works on both light and dark skin. However, it is more effective for darker, terminal hair than lighter, finer hair.
- Compared to other lasers, its wavelength offers the deepest penetration and superior melanin absorption.
These unique characteristics make the diode laser the most suitable technology for laser hair reduction, allowing safe and effective treatment of all skin and hair types, for all body areas.
Speed and Efficacy
- Diode laser hair removal is so popular because of its speed and efficacy.
- A single session rarely takes as long as an hour anymore. In fact, it is an office-hour procedure, that it is quick & ensures a speedy recovery.
- This procedure has been proven to achieve ‘permanent hair reduction in 90% of the cases.
- It ensures a stable reduction in hair regrowth after a treatment regime.
Pre-Procedure
- Your doctor will discuss with you your medical history, the risks and benefits of treatment, and your expectations from it beforehand.
- Don’t shave, wax or use other hair removal methods like plucking or electrolysis anytime before a laser hair removal on face treatment session.
- Stay away from the sun, tanning beds, spray tans, tanning lotion, and chlorine water for at least a month before the treatment.
- You can’t receive the treatment if you are facing a sunburn or even a sun tan, in order to avoid side effects like hyperpigmentation.
- Don’t use scrubs, glycolic acid, and retinol creams for 2 days before treatment, and chemical peels since for 2 weeks prior.
- Start using face mists and additional moisturizers if you find your skin getting more dry.
- On the day of the procedure, your doctor will explain the procedure to you step-by-step and address all your concerns.
- Thereafter, he will take your consent for the procedure, and only then will it begin.
Diode Laser Hair Removal Treatment Process
How many Diode Laser Hair Removal sessions are needed?
The number of diode laser hair removal sessions depends on the body part involved in the treatment. If you have any underlying conditions, such as PCOD, you may require more sessions than normal. For instance, a diode laser for facial hair removal and areas like the underarms requires about eight to ten sessions to get the desired laser hair removal treatment results. On the other hand, removing the bikini line and leg hair can take six to eight sessions. A couple of additional touch-up treatments may be required for even better results.
What are the benefits of Diode Laser Hair Removal?
Diode laser hair removal offers some unique benefits that include the following.
- Safer and deeper penetration into the layer of the skin.
- It removes some of the hair permanently.
- Hair regrowth is finer and lighter.
- The diode laser has a longer wavelength. Hence, the results are even better for dark-skinned people.
