Estrogen also rises during pregnancy, and that, combined with progesterone, can contribute to the formation of melasma, which appears as dark brown spots or patches.
Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males). [1]
The symptoms of melasma are dark, irregular, well-demarcated, hyperpigmented macules to patches. These patches often develop gradually over time. Melasma does not cause any other symptoms beyond the cosmetic discoloration. [4] Patches can vary in size from 0.5 cm (0.2 in) to larger than 10 cm (4 in) depending on the person.
High estrogen is typically defined as “levels exceeding the normal range” for a specific age and menstrual phase, often accompanied by other symptoms (more on this soon), she says.
Skin cancer is the most common form of cancer, globally accounting for at least 40% of cancer cases. [5] [20] The most common type is nonmelanoma skin cancer, which occurs in at least 2–3 million people per year. [6] [21] This is a rough estimate; good statistics are not kept. [1]
Antioxidants: Free radical damage (which you can get from sun exposure) is a known cause of skin pigmentation disorders, including melasma. Antioxidants, like niacinamide and retinol (vitamin A ...
Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. [1] It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma). [1] [2] In women, melanomas most commonly occur on the legs; while in men, on the back.

Aromatase excess syndrome (AES or AEXS) is a rarely diagnosed genetic and endocrine syndrome which is characterized by an overexpression of aromatase, the enzyme responsible for the biosynthesis of the estrogen sex hormones from the androgens, in turn resulting in excessive levels of circulating estrogens and, accordingly, symptoms of hyperestrogenism.
