Melasma or chloasma are darker pigment spots that can be found on the face. Melasma spots are usually chronic and recurrent and is typically a yellow-brown color that can affect the appearance. Melasma is different from freckles or sunspots because the growth is much deeper.
Melasma growth is a result of UV damage that increases pigmentation in the skin. Poor tissue circulation, cell lysis and melanin production can cause melasma to grow. Over time, the pigmentation will increase and grow larger.
Some of the main causes of melasma growth include genetics, lack of sleep, stress, or UV damage. To reduce melasma, it is important to have enough sun protection that has both UVA and UVB protection. Inadequate sun protection can cause melasma to worsen and cause more spots to form.
