Melasma is a common pigmentation disorder that causes brown or gray spots on the skin, primarily on the face.
Melasma can mainly be found in people with light brown skin to dark skin tones, especially in areas that are exposed to the sun a lot. Women are particularly susceptible to melasma, and it can appear as brown spots on the face, especially on the cheeks, bridge of the nose, and forehead.
The most common places where melasma appears on the face are:
- bridge of the nose
- upper lip
There are several types of melasma. According to the depth of settlement, the following types are found:
- Epidermal - located in the epidermis layer. At this time, the pigment spot is usually light-colored, sharply demarcated, and easily detected using an ultraviolet lamp. Epidermal melasma is the most easily treatable type.
- Dermal - in this case, the pigment spreads over the entire dermis layer. The color of the spot is dark brown and its contours are spread. Dermal melasma is the most difficult spot to treat.
- Mixed - in this case, the spot is in both the dermis and the epidermis, so it has a diffuse contour and a different color. Some areas respond well to treatment and some poorly.
