Superficial (Epidermal) Pigmentation

First, what is a KTP laser?

KTP is an abbreviation for the chemical: Potassium titanyl phosphate. The KTP laser is generated by a neodymium:YAG laser beam directed through a potassium titanyl phosphate (KTP) crystal to produce a beam of visible light at 532nm wavelength, which appears green, and is well suited to the treatment of Epidermal (superficial) pigmentation.

For deeper pigmentations of the skin (dermal layer) the ND:Yag laser creating a laser beam in the near infrared spectrum at a wavelength of 1064nm is more suitable. At City laser Clinic, we understand the distress and embarrassment that skin lesions can cause, particularly when darker and covering larger parts of the visible skin.

City Laser Clinic uses the MedLite Laser because it is the best most effective KTP Laser device currently available, and provides 4 different types of therapeutic laser beam, suited to different therapies.

What is the KTP Laser commonly applied to treat?

The KTP laser is well suited for the treatment of Superficial Pigmentation of the skin, known as Epidermal Pigmentation. These types of pigmentation are inherently close to the surface of the skin (epidermal layer) and are usually caused by sun exposure or made worse by sun exposure, and include:

Solar lentigos (Liver Spots)

Solar lentigos (Liver Spots) are commonly occur on our skin and are more likely to arise as we grow older and particularly over the age of 40, they are more common, and more noticeable in those of us that have had more exposure to the sun and the ultraviolet radiation in sunlight.

These skin blemishes occur in a range of colours from light brown to red and even dark red or black.  The darker solar lentigos (Liver Spots) can be mistaken for more serious skin issues including skin cancers such as melanoma.  At City Laser Clinic, we often refer clients to their General Medical Practitioner for assessment and when in doubt will not treat until a Medical Clearance is provided.

Solar lentigos (Liver Spots) are more common and noticeable in the parts of the body usually exposed to direct sunlight such as the hands and face including our forehead, as well as the shoulders, arms, but for those who sunbake, or have sunbaked, regularly these skin blemishes can appear on the back, legs, abdomen and chest areas.

The usual request for treatment of these blemishes we receive at City Laser Clinic is for the visible parts of the body, including face, hands and forearms; these being the parts of our bodies most commonly exposed to sunlight and more likely to form these unsightly spots.

Do these Liver Spots mean I have other health problems?

The term “Liver Spot” is a term that has arisen historically because it was believed that Liver Spots were due to liver problems.  Modern medicine informs us that Liver Spots are not medically related to liver problems, but they do have a similar colour and shape to liver.

In the vast majority of cases Liver Spots pose no threat to health, and no treatment is necessary other than for cosmetic reasons. Occasionally, they have been known to obscure the detection of skin cancer. Some people wish to have these spots removed as they consider them unsightly; this can be done by various means including electrosurgery, laser treatment and cryotherapy.

At City Laser Clinic, our therapists have the experience, training and qualifications as well as the equipment to provide safe an effective treatment of skin pigmentations. As with all Laser therapy treatments, the frequency and number of treatments will depend on your skin type, the area affected and the size of that area.  Contact us to arrange a free consultation to discuss a treatment plan that suits your needs.

Freckles

Freckles are clusters of concentrated melanin and are most visible on people with light coloured skin (fair complexion); Freckles are most noticeable on people with fair skin and red or blonde hair. While freckles are most noticeable on persons with fair complexion, they can occur on anyone irrespective of their ancestry and genetic background.

Freckles are predominantly found on the face, although they can also appear on any part of the body exposed to the sun, including the hands and the shoulders. Freckles commonly seen on children and some people associate them with an appearance of being younger. The formation of freckles is triggered by exposure to sunlight. The exposure to UV-B radiation causes our body to increase melanin production, which usually causes freckles to become darker.

Upon exposure to the sun, freckles will reappear if they have been altered with creams or lasers and not protected from the sun, however freckles usually fade as we grow older and with reduced exposure to the sun. Freckles are not a skin disorder, but while some people view freckles as enhancing a youthful look, some view freckles as blemishes and seek treatment to reduce their appearance.

As with all Laser therapy treatments, the frequency and number of treatments will depend on your skin type, the area affected and the size of that area.  Contact us to arrange a free consultation to discuss a treatment plan that suits your needs.

Cafe-au-Lait Macules (Spots)

The term “Café au Lait” is French for milk coffee and refers to the light-brown colour of these pigmented birthmarks. While these spots do not cause any ailment themselves, having multiple spots has been linked with some medical conditions including neurofibromatosis (NF), a genetically-inherited condition affecting nerve tissue and causing tumours known as neurofibromas.

These tumours are usually harmless but can cause damage by compressing nerves and other tissues. As with all Laser therapy treatments, the frequency and number of treatments will depend on your skin type, the area affected and the size of that area.  Contact us to arrange a free consultation to discuss a treatment plan that suits your needs.

Dyschromia

While significant variation in skin colour (Dyschromia) is not a cause for medical concern directly, the consequences of reduced and varied patches of skin pigment in the skin may mean the person is more likely to incur skin damage from exposure to the sun leading to a greater than normal risk of developing skin cancer.

Dyschromia can also arise from healed injuries to the skin (scar tissue), as well as from some skin infections. Discolouration can remain in the form of permanent hyper-pigmentation.  Radiation therapy may also cause Dyschromia. As with all Laser therapy treatments, the frequency and number of treatments will depend on your skin type, the area affected and the size of that area

Are there any Precautions to take during treatment?

As with all laser treatment, you must avoid exposure to direct sunlight before treatment, during treatment and for some weeks following treatment.  At City Laser Clinic, our experienced qualified therapists will advise you based on your skin type and the nature of the treatments that you are receiving. The City Laser Clinic therapists do sometimes need to refer clients to their General Medical Practitioner for assessment and when in doubt will not treat until a Medical Clearance is provided.
