Pigmentary disorders in the skin can be congenital or birth acquired or artificial. Congenital abnormalities usually appear from birth or a few years later and persist throughout life.
For example café au lait macules (CALMs), nevus of Ota, nevus spilus, Becker's nevi and Peutz-Jeghers syndrome. While the acquired pigment disorders usually appear in adulthood are usually due to the influence of sunlight, such as lentigenes, freckles and melasma.
While artificial pigments such as permanent tattoos both on the eyebrows and on other skin parts (body) or traumatic tattoos. Q-Switched Nd: YAG laser is a laser that is used to remove tattoo pigment colors (especially blue, brown, black and red, except green) and some pigment abnormalities obtained and birthmarks.
To be able to get rid of unwanted pigments, repeated laser therapy is needed at intervals of between 4 - 8 weeks. The amount of therapy required varies greatly, depending on the type of pigment abnormality, size, location, color and age of the patient. In patients with tattoos, please note how long the tattoo is made and the type of ink used.
What pigment or brown spots can be removed with a Q-Switched Nd: YAG laser?
This laser is commonly used to remove brown spots due to age, freckles and brown spots from birth. This laser should not be used to remove brown / black patches suspected of cancer or malignant cancer. The doctor will decide.
Why doesn't the Q-Switched laser remove my normal skin color?
This laser beam is designed to destroy melanin pigments that are too dense. In treatment, it can happen that the skin is too white (hypopigmented), but this condition can usually heal itself.
How many treatments are needed?
For certain skin pigment disorders, usually 80% has been lost in 1 treatment. For deeper types of pigment abnormalities, it needs several repetitions at intervals of 4-6 weeks, as well as tattoo removal that needs to be done about 3-6 times depending on the type and depth of ink used for tattoos.
Can the disorder come back again?
Usually not. Some birthmarks can recur after a few years, but can be treated again with this laser with the same effective results.
How is the treatment after the laser?
For 3 days to 1 week the laser wound is covered with plaster, and efforts should not be made to contact water except the compress fluid. If necessary may be given a topical antibiotic cream by a doctor.
If you feel pain after laser therapy with Q-Switched Nd: YAG, the doctor will give you an analgesic drug (pain reliever).
If there is swelling, it can be compressed with an ice pack.
Tips after undergoing laser therapy
Avoid direct sunlight, and always use sunscreen.
Do not rub, scratch or squeeze on the laser area. Use wound protection tape especially if the area is often rubbed against clothing or jewelry.
Do not use decorative make-up until the scab wound (crust) peels (usually 2-4 days).
Avoid swimming and heavy exercise if the crust has not been peeled.
If the laser area has signs of infection (pain, redness, swelling or pus), immediately re-control the clinic.
What are the side effects and possible complications after pigment laser therapy?
This laser only touches the skin in a very short time. During laser therapy, you can experience pain such as being stapled with rubber. Some areas feel more sensitive than others. After the laser action is finished, the skin feels a little uncomfortable, like after being exposed to sunlight. Usually the discomfort disappears in a day. The skin can become red for 2-4 weeks. After the red color disappears, the skin will return to normal both in color and texture.
Laser action can cause injuries such as minor burns and may take several days to heal. The process can cause swelling, swelling and swelling, which usually heals within 4 - 10 days.
Scar (scar tissue) is rare, if the post-laser instructions are done correctly.
Some tattoos (such as green) or pigments that are located very deep sometimes cannot be removed with laser therapy despite repeated treatments. For that we need to do other alternative therapies.
Most sufferers will experience blanching (hypopigmentation) in the laser-treated area, the skin appear paler in color than the surrounding skin. The skin will return to normal after 2-4 weeks. Repeated laser therapy will make the loss of pigmentation more permanent.
There can be a risk of increased pigmentation (hyperpigmentation), but this will usually fade after 2-6 months after laser therapy.
