What is Seborrheic Keratosis?
The most common place of occurrence can be face, chest, back or shoulders. They are usually skin coloured, brown or black with waxy, scaly or raised appearance. They are absolutely harmless, symptomless and non-cancerous. Sometimes they can be itchy and may cause discomfort. It is believed that they are caused due to the build-up of ordinary skin cells. They are neither contagious nor hereditary. They can be related to the age and excessive exposure to the sun. The occurrence starts with a flat appearance and with time it starts to elevate which gives the impression that it is pasted on the skin surface. There can be one or multiple lesions.
Treatment of Seborrheic Keratosis
Despite its benign nature, people opt for a treatment because of cosmetic reasons. It can be bothersome to have these lesions on critical areas like the face. There are different treatment options available like cryotherapy with liquid nitrogen, shave excision, curettage and CO2 laser vaporisation. All the procedures are done under local anaesthesia. The preference for CO2 laser is rising exponentially as this is a painless procedure and requires very less time for recovery. The biggest advantage is that this procedure does not leave any scars behind, thus, gives better results.
Do these lesions grow back after removal?
It can be treated but unfortunately, it cannot be cured. Once the lesion is treated it does not regrow, but new lesions can appear at the different site. Even if they are left untreated, they are not harmful as long as they are not changing the size, colour or become painful, their treatment can be avoided.
At Renew Skin and Health Clinic, CO2 laser treatment is offered to deliver the best results, especially for critical areas like the face.
What to expect after the treatment
After vaporising the lesion, there will be slight redness which fades away in a couple of days. After that, there will be a hard scab which usually falls off in 10-12 days leaving behind a pink skin. The difference in skin tone vanishes when it is exposed to light making your skin tone uneven. There are no side-effects of the Seborrhoeic Keratosis treatment if the right aftercare is followed.
