Pigmentation is a common skin condition, recognised as dark spots, sun spots and age spots. This causes uneven brown patches that occur on the face, hands, decolletage and shoulders. Uneven pigmentation is caused by sun exposure, in particular harmful UVA rays. Sun spots can take approximately 10-20 years to develop and can cause the skin to age considerably. There are several causes of pigmentation.
Alongside sun exposure, Melasma is caused by hormonal changes such as pregnancy, and hyperpigmentation can often be caused by certain medications. When blemishes, or other skin conditions heal they can often leave a discoloured mark behind which causes post-inflammatory hyperpigmentation.
