Many people have probably heard of YAG Laser hair removal technology, which is considered the most popular hair removal method due to its many visible results. It is also a method that many beauty institutes continuously offer. But have you ever wondered why YAG Laser is considered the best? And how does it work? Let’s get to know YAG Laser better.
What is a YAG Laser? How does it work?
YAG Laser technology, with a 1064 nm wavelength, is used for hair removal by targeting hair roots with heat. This process causes the roots to stop growing and eventually atrophy, leading to gradual hair loss. Each session can remove 20-30% of hair in the treated area, so experts recommend 5-8 sessions for complete removal. Noticeable results typically appear after the 4th or 5th session, with remaining sessions enhancing smoothness and removing any leftover hair.
Highlights of YAG Laser
Currently, there are many types of laser energy waves for hair removal, but YAG Laser is considered the most effective and suitable for Asians. Its wavelength can penetrate deep into the skin, up to 7 millimeters, and effectively target the pigment of dark hair better than other laser types. Additionally, YAG Laser has no side effects to worry about, as the laser energy waves do not affect the surrounding skin. After the procedure, you can continue your normal activities.
Who is YAG Laser suitable for?
YAG Laser is a new type of laser energy wave that can remove various types of hair. However, it is most effective for Asians with dark hair and fair to yellowish skin.
5 things to do after laser hair removal
1. Apply moisturizer to restore moisture to the skin.
Since the skin that has just undergone laser hair removal will be quite dry and may be irritated or swollen, applying moisturizer or skin care cream is essential to restore the skin’s moisture and return it to normal as soon as possible. Choose a product suitable for sensitive skin that does not cause irritation, and ensure the cream is not too heavy or sticky.
2. Apply aloe vera gel to soothe the skin.
If you experience swelling and redness after laser hair removal and are unsure what to use to reduce these symptoms, natural aloe vera gel without other chemicals is a good choice. Aloe vera gel can effectively reduce skin irritation and redness and also helps with moisture.
3. Protect the skin from UV rays.
After laser hair removal, the treated area will be especially sensitive to light, making it easy to get sunburned and prone to dark spots if exposed to sunlight. Therefore, always apply sunscreen when going out or even staying at home. Use a sunscreen with SPF 30 or higher and ensure it has a PA+++ rating. Apply the cream thoroughly and avoid applying it too thinly.
4. Gently exfoliate while showering.
Wait about 2-3 weeks after laser hair removal to allow the skin to recover and return to balance. During this period, the lasered hair will start to fall out. To aid this process and help exfoliate dead skin cells, gently scrub your skin with a towel while showering.
5. Use hair trimming instead of shaving, plucking, or waxing.
If new hair grows while waiting for the next laser treatment, use scissors to trim the hair to reduce the risk of skin irritation and prepare the skin and hair for the most effective laser treatment. Avoid shaving, plucking, or waxing your hair.
5 things you should not do after laser hair removal
- Do not pick, scratch, or scrub the treated area.
In the first 1-2 weeks after laser hair removal, avoid picking, scratching, or scrubbing the treated area, as the skin is initially irritated and dry. Scrubbing the skin will further irritate it and may cause inflammation.
- Avoid exposure to heat.
The treated area will be exposed to heat and may still retain heat from the laser energy, causing temporary irritation or swelling and redness. For at least one week, avoid hot showers, hot spas, steaming, saunas, or activities that cause excessive sweating to prevent further skin irritation. Instead, use cold, normal temperature, or warm water for showers.
- Avoid being in the sun.
UV rays are harmful to the skin, and skin that has just undergone laser hair removal is more sensitive to light. Avoid exposing the treated area to the sun to prevent burning or dark spots. If necessary, wear loose-fitting clothing and always apply sunscreen for protection.
- Avoid using skin products that contain chemicals.
Sensitive and irritated skin is more easily damaged, so avoid using skin products with perfume, alcohol, or irritating chemicals, such as those that exfoliate or whiten the skin.
- Do not shave, pluck, or wax your hair.
During the laser hair removal course or while waiting for the next session, do not shave, pluck, or wax your hair. Laser hair removal requires a small amount of hair and the hair roots to act as a medium for sending energy waves.
In addition to YAG Laser, what other types of hair removal lasers are there?
- Diode Laser
Diode Laser has a wide range of wavelengths (800-810 nm, 940 nm, and 1064-1350 nm) and can be adjusted to suit different hair and skin types. It removes hair to the roots without leaving any traces of the laser and is painless.
- Alexandrite Laser
Alexandrite Laser has a wavelength of 755 nm and uses Alexandrite crystals to produce light. It is very popular in Europe and is suitable for fair to medium skin tones and light-colored hair.
However, some people prefer IPL (Intense Pulsed Light) for hair removal, even though it is not a laser energy wave. IPL is popular because it is cheaper, but the results are slower compared to other types of lasers and not suitable for people with dark skin and a lot of hair.
New and superior technology for effective hair removal
With advancements in beauty technology, the YAG Laser has been enhanced to improve hair removal efficiency for all hair types, skin tones, and conditions. The latest laser hair removal technology combines Long-pulsed Alexandrite Laser, YAG Laser, and Diode Laser, offering a smoother hair removal experience.
