Intense pulsed light (IPL) is a recent light technology introduced to remove multiple skin disorders such as pigmentation and fine veins (telangiectasia).It is also popularly known as "photo rejuvenation" or "photo facial". The device is not a laser but a broad band light source with a range of wavelengths, which can target different skin lesions at the same time. Different filters are used depending on the skin type and the predominant target. The improvement is more gradual and subtle than compared to laser therapy.
What is it used for?
Low-Level Laser Light is one of the most effective therapies to treat hair loss. Lasers are widely used in medicine The laser energy used to stimulate hair growth is visible in the red light spectrum. The laser light used in promoting hair growth is defined as Low-Level Laser Therapy (LLLT) Light from a laser in a specific wavelength has an effect on your body when it is applied for a sufficient length of time. laser light is absorbed by target tissue molecules, the energy level of the molecules is increased and the molecules respond by ‘working off’ the excess energy with adaptive changes. These changes may be chemical or physical, and they may have biological effects on the target tissue or surrounding tissues. Hair growth using LLLT is not a one-time ‘fix’ for hair loss. It must be repeated at intervals to maintain results. Typically 3 to 4 sessions per week for 20 to 25 minutes is the suggested treatment frequency, and results usually take approximately 4 to 6 months. Once hair growth is achieved, an ongoing ‘maintenance’ schedule of 1 to 2 sessions per week is strongly recommended to maintain new growth, and keep the hair looking healthier, fuller, and more vibrant.
Non - ablative laser skin rejuvenation is a recent laser technology introduced to treat wrinkles and scars. This new laser system is believed to promote the synthesis of new collagen in the dermis without ablating or removing the overlying epidermis, thus sparing patients a prolonged downtime and healing period. This also minimizes the potential complications such as infection,scarring and post inflammatory pigmentary changes. The improvement is more gradual and subtle than compared to the ablative lasers.
Presently there are several lasers which can be used for non-ablative skin rejuvenation. They can be broadly divided into two groups. Some of these are lasers traditionally used for the removal of skin pigment or blood vessels e.g. Q-Switched Nd YAG Laser, pulsed dye laser. The second group consists of lasers which are specifically manufactured for the sole purpose of non-ablative laser procedure by stimulating collagen synthesis e.g.1320 nm Nd YAG laser, 1450 nm diode laser, and 1540 nm erbium glass laser. It has not been established which is the most effective laser.
Fractional co2 laser is the latest in skincare technology. Conventional Lasers or Intense Pulse Light (IPL) targets a large portion of the skin (about 1 cm-2 cm diameter) in a single Laser beam. Fractional Laser, on the other hand, uses numerous microscopic Laser beams, which create tiny Laser "punctures"(each of about 0.05 mm in diameter) into the skin while leaving the untreated surrounding areas intact. The untreated tissue helps to accelerate the healing process and rejuvenate the skin by promoting microcirculation and new cell genesis.
The Q-Switched Nd: YAG Laser is a type of laser developed to remove blue, brown, black and possibly other colors of tattoo pigment and certain brown growths and birthmarks from the skin. Although laser surgery is effective in most cases, no guarantee can be made that a specific patient will benefit from the treatment. Repeated laser treatments are often necessary. The tattoo or pigmentation will be treated at intervals of two months or longer until either the entire pigment is removed or further improvement is deemed unlikely. The number of treatment with the Q-Switched Nd: YAG Laser will vary depending on the lesion, size, location, color and age of the patient and age of tattoo. Most likely total 3-7 visits/treatments or more will be necessary.
