The Q-Switched Nd Yag Lasers

In Q-Switched mode, the very short pulses (6ns) deliver very high peak power granting the most efficient photo acoustic effect, with no thermal interaction with tissues. As a result, the unwanted pigments of the skin fragmented in small particles that are expelled through the phagocytes.

Pigmented lesions

Pigmented lesions usually refer to melanocytic proliferations. The melanocyte comes in a variety of shapes and sizes. Benign proliferations are often called moles or nevi. Melanocytic proliferations are not the only reason for pigmented lesions. There may be an increase in melanin, unassociated with an increase in melanocytes. Aging spots, solar lentigo, cafe-au-lait macules, and dermal pigmentations as nevus of Ota are nowadays easily treatable with lasers. Q-switched Laser devices heat the melanin in a pigmented lesion, which causes the lesion to disappear.

Main Treatments:

Cafe-au-lait macules
Melasma / Cloasma
Nevus of Becker
Nevus of Ota / Ito

Cafe-au-lait macules:

Cafe-au-lait macules are pigmented birthmarks. The name
Cafe-au-lait macules refers to their light-brown color. While
Cafe-au-lait macules are usually not associated with any medical problems, having many such spots could be linked with some serious problem.
The Q-switched lasers technology is the most effective and safe
solution to remove Cafe-au-lait macules.


A benign solar lentigo, or lentigines (plural), is a small, circumscribed benign pigmented patch surrounded by normal-appearing skin. Lentigines are caused by melanocytic proliferation on the basal layer and may evolve slowly over years, or they may be eruptive and appear rather suddenly.

Pigmentation may be homogeneous or variegated, with a color ranging from brown to black. Lentigo is one of the most common forms of pigmentationand is caused by sun exposure.

Melasma / Chloasma:

Melasma (also known as chloasma or the mask of pregnancy when present in pregnant women) is a tan or dark facial skin discoloration. Although it can affect anyone, melasma is particularly common in women, especially pregnant women and those who are taking oral contraceptives or hormone replacement therapy (HRT) medications. Melasma is thought to be the stimulation of melanocytes or pigment-producing cells by the female sex hormones estrogen and progesterone to produce more melanin pigments when the skin is exposed to sun. Women with a light brown skin type who are living in regions with intense sun exposure are particularly susceptible to developing this condition.Genetic predisposition is also a major factor in determining whether someone will develop chloasma or melasma.

Dyschromia is a disorder of pigmentation of the skin. It can be caused by hyperpigmentations that are a common condition in which patches of skin become darker in color than the normal surrounding skin. Freckles, age spots, lentigines and other darkened skin patches can become darker or more pronounced when skin is exposed to the sun.

There are now several highly effective laser treatments to remove pigment and dyschromic skin appearance without scarring.

Nevus of Becker:

In 1948, S. William Becker described 2 young men with acquired melanosis and hypertrichosis in a unilateral distribution. Since then, this condition has been termed Becker nevus. The nevus generally first appears as an irregular pigmentation (melanosis or hyperpigmentation) on the torso or upper arm (though other areas of the body can be affected), and gradually can enlarges irregularly, becoming thickened and often hairy (hypertrichosis).

Becker’s nevus is considered a benign lesion and lasers offer long-lasting hair removal solution and may also be effective in elimination or reduction of hyperpigmentation.

Nevus of Ota / Ito:

Nevus of Ota originally was described by Ota and Tanino in 1939 is a hamartoma (benign malformation) of dermal melanocytes. Nevus of Ota presents as a blue or gray patch on the face, which is congenital or acquired, unilateral or bilateral, and, in addition to skin, it may involve ocular and oral mucosal surfaces.

Nevus of Ito, initially described by Minor Ito in 1954, is a dermal melanocytic patch affecting the supraclavicular, deltoid, or scapular regions. Nevus of Ito often occurs in association with nevus of Ota in the same patient but is much less common Q-switched laser treatment is unquestionably the current treatment of choice for nevi of Ota and Ito and it works via selective photothermal and photomechanical destruction of dermal melanocytes and melanophages.

Tattoo removal:

Tattooing is commonly widespread and nowadays the demand for tattoo removal is rapidly increasing. The only efficacious modality for tattoo removal, which affords best results to be achieved and no significant adverse effects reported is the Q-Switched laser, which causes a selective photoacoustic fragmentation of the different ink particles within the skin, as well as their absorption by the phagocytosis, with no thermal injury to the surrounded tissue.

Wavelengths used are usually complementary to the colour to be removed and are consequently able to effectively treat different tattoo ink particles..

Carbon Blast (Black Doll TM) Laser Facial Treatment

The famous Carbon Ion Nano-Lambency therapy combines the ND: YAG (1064 nm) laser and Carbon Ion Powder to effectively brighten your skin, reduce your open pores, reduce pigmentations (Nevus of Ota, coffee spot, age spot, freckle etc) and stimulate the regeneration of the collagen fiber of your skin.

Skin is the largest organ of the body. It is made up of two layers, the upper ‘epidermis’ and the lower ‘dermis’. The epidermis and the dermis are further divided into other layers.

The lower most layer of the epidermis is known as the basal layer and it contains organelles called ‘melanosomes’. These melanosomes contain cells called melanocytes which produce a pigment called ‘melanin’. The color of skin depends mainly on this melanin and the amount of melanin present in the other layers of the epidermis. The thickness of epidermis and vascularity of the epidermis are other factors affecting the color of skin.

The principle of carbon ion nano-lambency therapy

  1. Carbon powder, as an exogenous artificial color agent, possesses strong adsorptive capacity to absorb the dirt deep in the pores and attract pigment in epidermis layer.
  2. The carbon powder has excellent absorption properties on 1064nm laser light.
  3. The medical graded laser generates high energy and heat to stimulate the regeneration of the collagen fiber under the skin. The body’s natural repair function leads to the collagen’s redeposition and rearrangement, which results in reducing the wrinkles and fine lines, shrinking pores, smoothing skin, regain a brighter, more even and luminous complexion.
