Dark patches due to Hormonal Imbalances
Acanthosis Nigricans is a condition when the larger dark patches develop in and around skin folds, such as the back of the neck, axilla, and groin, where it presents as velvety hyper-pigmented patches. This skin condition is caused by changes in hormone levels. It can affect both men and women.
What causes Dark Patches?
Melanin is a natural substance that gives colour to your hair, skin, and eyes. Melanin is a common cause of dark patches or hyperpigmentation.
Several factors that cause an increase in melanin production are sun exposure, hormonal influences, skin injuries and age.
· Sun Exposure
Sun exposure is the main reason of hyperpigmentation as it's daylight that triggers the creation of melanin. Melanin works as your skin's common sunscreen by shielding you from destructive UV sun rays, which is the reason individuals tan in the sun. Be excessive exposure may disturb this process, prompting hyperpigmentation.
When dark spots have created, the exposure to sun can intensify the issue by making age spots, melasma and post-inflammatory hyperpigmentation spots darker.
· Hyperpigmentation and hormones
Hormonal impacts are the key reason of a specific sort of hyperpigmentation called to be Acanthosis Nigricans. It occurs when estrogen and progesterone invigorate the overproduction of melanin when skin get the sun exposure. Hyperpigmentation can likewise be a result of certain hormone treatments.
· Hyperpigmentation and age
As skin ages, the quantity of melanin-producing cells diminishes however the remaining ones increase in size and it leads to uneven distribution of cells on the body skin. These physiological changes describe the increase of age spots in those aged above 40.
· Hyperpigmentation and skin wounds and injuries
The post-inflammatory hyperpigmentation occurs from skin injury such as cuts, burns, acne, psoriasis, or chemical exposure. Skin is left discoloured after the injury is healed.
