Uneven complexion is the irregular darkening of the skin. The cause: overproduction of melanin, the pigment responsible for skin and hair color. It can be caused by sun exposure, pollution, hormones, irregular cellular turnover, and post-inflammatory hyperpigmentation.
Uneven skin texture is commonly a result of excess dead skin cells that build up on the surface of the skin. Uneven skin texture can be caused by specific skin problems such as rosacea or acne, but it can also be a product of sun damage, aging or the result of using the wrong skincare products.
