What is Melasma?
Melasma (also called Chloasma) is an extremely difficult condition to treat using traditional methods. It usually effects women. Melasma is an hormonally induced pigmentation condition generally characterised by relatively symmetrical pattern of dark pigmentation on the face often around the eyes, cheek, lip, chin or brow. Melasma appears as grey-brown pigmentation and looks a bit like dirty or discoloured skin patches. Melasma is stimulated by UV light. If Melasma is treated incorrectly, it can worsen. Sun protection is necessary to reduce the effects of Melasma.
There are two types of melasma characterised by the depth in the skin of the pigmentation. Whilst epidermal pigmentation may temporarily fade with topical lightening agents, the deeper, dermal form of melsama cannot needs to be treated with Revlite Q-switch ND-Yag laser to break down the pigment to smaller particles for the lymphatic system to remove from your skin. A patient with melasma usually has a combination of both dermal and epidermal melasma.
The Revlite works by being selectively attractive to the pigmentation in the dermis and epidermis. The extremely short pulse duration of the revlite shatters the pigment which is absorbed by the lymphatic system.
Approximately six treatments are provided for melasma at one to two week intervals. Some melasma has cleared in as little as two treatments with Revlite laser. The longer you leave your melasma untreated the more difficult it is likely to be to remove it. After each treatment you will notice that the melasma will progressively lighten. Care needs to taken during and after the course of treatments to minimise or eradicate sun exposure. Exposure to UV light will once again stimulate the melanocytes and the melasma can return!
