Melanocyte Simulating Hormones are collectively known as MSH, which belong to the group of peptide hormones that are produced by the cells in the intermediate lobe of the pituitary gland. These hormones are responsible for the production as well as release of melanin pigment by the melanocytes present under the epidermal layer of hair and skin. MSH production also occur in arcuate nucleus of the hypothalamus, which affects sexual arousal and appetite of human beings. The increase of MSH production is responsible for darkening of skin during pregnancy. Go through the following lines in order to have an idea on the production of MSH, and its effect during pregnancy.
One of the prime effect of MSH production during pregnancy is the darkening of skin. Though it is not experienced by each and every woman, but it is quite a common phenomenon. Melasma is a common disorder associated with the darkening of the skin, which proves the increase of MSH production in this region. As it appears like mask, it is known as mask of pregnancy.

During pregnancy, Montgomery glands, located in the areolae region, also increase in size which causes brown lumps in this region. Increase of MSH production along with the under activity of sebaceous glands and over activity of sweat glands give rise to acne, which are tiny eruptions that appear on the face. During pregnancy, the sweat glands become more activated, thus causes heat rashes. During this time, the variation in the balance of estrogen and progesterone hormones are also responsible to some extent for all these skin disorders. It can be said that it is actually the cumulative effect of all the hormonal changes that takes place during pregnancy.
