Melasma is a condition with unclear origins. The likelihood of developing melasma can increase if you take OCs or HRT, or are pregnant. Melasma can occur in various places, on the face and neck, and across entire arms.
Melasma, also called melanosis, is caused by an overproduction of melanin and an overgrowth of melanocytes.
Melasma onset can occur at any age, but it more often occurs in women during the reproductive years because her levels of estrogen and progesterone are increased.
Melasma cure is not easy to find but out of 10 patients, 40% will improve in a few years. The age ranges from 25-50 and there is a connection to hormones.
Melasma hides behind dark skin, and it initially looks like chickenpox. However, the first symptom is often surprise of an unusual symmetry with this markers on your face. Although the disorder is not life-threatening, it can debilitate your emotional self-esteem as well as violating confidence in yourself as you get older by displaying darker pigmentation patches on your skin.
The root cause of Melasma is not yet understood. Known risk factors are dark skin, birth control pills, hormone drugs, pregnancy and hormonal changes such as menopause etc. Therapy is given to control the pigmentation by using various combination of topical treatments with sun protection or laser treatments.
Melasma is a pigmentation disorder that mainly involves women who are pregnant or have gone through the menopause and have hormonal imbalances.
In infants melasma often times goes away shortly after birth. Melasma can be treated with over-the-counter medication called hydroquinone, beta carotene, retinoids and as it progresses topical bleaching agents are used such as: azelaic acid, kojic acid or soy creams. However, there is an increased risk of side effects in some people using oral retinoids due to potential complications.
Melasma is a benign cutaneous disorder that causes degranulation of melanocytes and the deposition of varying amounts of brown pigmented material on skin.
Melasma can cause many symptoms such as facial blotchiness, "mask-like" facial appearance, hyperpigmentation. More rarely, it leads to vitiligo-like depigmented areas and irregularity in skin tone
It has also been show an association with hormone changes during pregnant and postmenopausal periods as well as that there might be links to environment impact such as medication, ultraviolet radiation, mineral overuse and deficiencies like zinc or to eat acidic food.
Melasma is a type of hyperpigmentation that occurs on sun-exposed skin. It’s most common on the forehead, around the eyes, and nose, but it can occur anywhere on the face. The cause of melasma is unknown; however, having one or more related diseases such as diabetes and thyroid conditions may be an important risk factor for developing this condition.
Melasma causes dark patches to form- purple brown for are present when someone has excess levels of estrogen in the body and there is artificial UV light exposure. Melasma typically occurs after menopause or pregnancy.
Melasma can also be found in people who naturally have darker skin color and might develop lenticular skin pigmentation due to reduce enough circulation of oxygen in their blood vessels called acral erythema lenticularis perstans (LPP).
Melasma develops due to hormonal changes, pregnancy, contraceptive medicines and causes some of the most severe cases of hyperpigmentation. The dark circles are caused by increased melanin which is caused due to pressure form melanocytes.
With increased understanding in genetics and better treatments available, the global hypo pigmentation market is expected to show a solid CAGR of 8% over next 4 years.
Based on an electron microscopy study performed by Palinka et al., the excess melanin can be found inside melanosomes in type A maley pigmented skin and outside in type B maley pigmented skin. Type B often has a few black mast cells left at each hair follicle entrance opening while type A exhibit altered epidermal cells with only empty nucleus “ghosts” as possible cause for hypopigmentation; however, DNA typing had not been done before this diagram was drawn up so it's unclear what caused these findings.
US government data from 1988
Melasma is a sensitive to sunlight with the most common cause being pregnancy or oral contraceptive use or melanocyte stimulation.
Melasma is typically pinkish-brown in color. It can form on both the upper lip and nose, forehead, cheeks, chin, chest and abdomen.
The formation of Melasma tends to be more problematic as it progresses unchecked because new lesions form as well as thickening of existing patches. Therefore, it’s important to monitor how recently the spots have been appearing, for how long the person has had them now and the shape of the spots themselves in order to know what type of treatment will work. Self-care should also include avoiding exposure to UV light sources like direct sunlight or tanning beds from which more extreme cases can progress quickly under their harsh oxidants.
