Melasma (a term derived from Greek word ‘melas’ meaning black) is an acquired blotchy, irregularly patterned, brown or sometimes grey-brown melanosis of the face and occasionally the neck, of poorly understood etiology but attributable to sunlight and genetic predisposition.
It is also known as chloasma and used for a pattern of asymptomatic superficial brownish pigmentation seen mainly in females.
The lesions are usually seen on the bridge of the nose, cheeks, upper lip and forehead. On the forehead, a linear area just above the eyebrows is common. The lesions are usually bilateral and often symmetrical.
They become more prominent after sun exposure. Usually the lesions appear during pregnancy but have also been seen in unmarried girls and males, females who have disturbed menstrual cycle, have been taking contraceptive pills since long are at increased risk of developing melasma.
Cause of Melasma
- Estrogen is the most important factor. This explains the prevalence of the disease in pregnancy and after use of oral contraceptives.
- Sun exposure: UVB light is an important cause
- Iron folate deficiency
- Cosmetics, fragrances
- Genetic factors
- Racial factors
Melasma can be either diffuse or may be mottled. It may be either totally epidermal (as in early cases) or mixed (as in later cases, when part of the pigment descends in to dermis.)
Cause and Manifestations of melasma
Hyper pigmented areas affected with melasma usually appear as blotchy patches. Melasma patches are not elevated above the level of the skin, but appear as flattened discolorations of tan or shade of brown from light to dark or gray.
Melasma is most frequently noticed on sun-exposed areas of the face, especially the cheeks, forehead, upper lip, nose, and chin. Scars and moles located inside a melasma patch may also undergo progressive darkening. Patches may appear in a symmetric pattern.
The three classic distributions for facial Chloasma hyper pigmentation are (a) malar, involving the cheeks; (b) centrofacial, involving the forehead, cheeks, chin and upper lip; and (c) mandibular, classically involving the chin and jaw line. Chloasma is not limited to the face, and is often seen in the dorsal extremities and sun-exposed areas.
Melasma is caused by proliferation of melanocytes and increased production of melanosomes. The tendency to suffer from Chloasma is inherited. Some females begin to experience the condition as a result of puberty-induced hormonal rises. In others, the hormonal changes of pregnancy are the probable cause.
Melanocyte possesses estrogen receptors that stimulate hyperactivity. Both estrogen and progesterone stimulate melanogenasis through this mechanism, and both are elevated during pregnancy. Ingestion of oral contraceptive pills and estrogen supplements produces melasma through the same mechanism.
Melasma is exacerbated by sun exposure, which accounts for its heightened incidence in those who receive greater amounts of UVB radiation. The etiology in males is less well understood, but is not thought to be related to hormonal causes; it may be testicular resistance.
Homeopathic treatment of Melasma
Homeopathy is one of the most popular holistic systems of medicine. The selection of remedy is based upon the theory of individualization and symptoms similarity by using holistic approach. This is the only way through which a state of complete health can be regained by removing all the sign and symptoms from which the patient is suffering.
The aim of homeopathy is not only to treat melasma but to address its underlying cause and individual susceptibility. As far as therapeutic medication is concerned, several remedies are available to treat melasma that can be selected on the basis of cause, sensations and modalities of the complaints.
For individualized remedy selection and treatment, the patient should consult a qualified homeopathic doctor in person. There are following homeopathic remedies which are helpful in the treatment of melasma:
