Removal of Pigmented Skin Lesions
Pigmented lesions on the skin are common, particularly among the ageing population, those frequently exposed to direct sunlight without UV protection. Skin pigmentation disorder could also occur due to genetic reasons, or from stress and dietary imbalances. These pigmented areas of the skin contain high concentration of melanin and vary in size shape and depth.
These lesions (common skin lesions include moles and actinic keratosis, among others) can be as small as a pinhead or as big as a fingertip, and sometimes as large as a hand. They usually, occur on the face, neck or arms.
Some pigmented skin lesions (an abnormal lump, bump, ulcer, sore or colored area on the skin) grow, spread or occur on exposed areas of skin and resemble malignancy causing concern.
Depending on the skin tone, several of these conditions can be selectively treated with laser. The most commonly treated conditions are solar lentigines (also known as age spots, liver spots or sun spots).
Frequently asked Questions
Here are a few points that may answer your questions about Rhinoplasty, to help you make an informed decision before opting for it.
The lesion’s border, shape, color, and size provides sufficient information with which to decide when a biopsy is warranted. Biopsy can reveal if the lesion is malignant
Lasers treatments performed by a trained physician, are safe and effective. There are many benefits to laser surgery including no needles for most patients, more effective lesion removal, and less risk of scarring. Lasers are effective for the treatment of hyperpigmentation, but are not free of side effects.
Some patients feel a slight sting, like the snap of a rubber band on the skin, followed by the feeling of sunburn. Though many treatments do not require anesthetics, some patients may need a local anesthetic cream or ice to numb the area
The most innovative methods include photo-rejuvenation that uses unique IPL (Intense Pulsed Light) technology. Pigmented lesions can be removed by a laser or chemical peel (AHA acids, TCA peel, etc.).
- Post-inflammatory hyperpigmentation, or PIH
- Discoloration from sun damage
- Age spots
Treatment benign pigmented lesions depends on the type and cause of the pigmentation and the underlying skin type. Possible options include bleaching cream, skin peels, IPL, pigment lasers, ablative lasers etc.
Malignant skin pigments include:
- Basal Cell Carcinoma (BCC)
- Squamous Cell Carcinoma (SCC)
If pigmented lesion has changed in shape or color, is bleeding or is persistently itchy, you must consult General Physician or Dermatologist to diagnose it. You may be advised a biopsy for investigation. If the lesion is suspected to be cancer, then you may be further tested.
There are more risks with the use of lasers than with lightening agents. These risks include worsening of the pigmentation, loss of normal skin pigmentation (hypopigmentation) or scarring of the skin (rare). Common side effects may include skin redness, swelling of the treated area, and moderate irritation as felt by a mild sunburn.
Post-laser procedure the skin may become red and swollen for the first 24 hours, so application of makeup or skin products must be avoided; must wear a sunscreen of 30 SPF or higher when exposed to sunlight. Avoid bathing with very hot water, strenuous exercise, or massage as also cosmetic treatments such as tweezing, waxing, bleaching or chemical peels for next 4 weeks.
Invasive treatments may require an extended recovery time of several weeks. A gentler laser skin rejuvenation treatment may require little or no downtime.
Laser skin pigmentation treatment can successfully reduce skin patches and pigmentation permanently. Laser surgeries for treating skin pigmentation may range from around Rs. 3000 to Rs. 5000 for a single session; the patient may have to undergo many sessions as the doctor sees fit.
