Definition

Uneven Skin Tone: Uneven skin tone may be referred to as: pigmentation disorder, or dyschromia. It includes hyper pigmentation or hypo pigmentation issues, meaning excess which is darker patches such as melisma, freckle, lentigens, nevus Hori (oestrogen hormone disorder) and xanthochromism.

Uneven skin tone may be referred to as:

  • pigmentation disorder, or
  • dyschromia.
  • It includes hyper pigmentation or
  • hypo pigmentation issues, meaning excess which is darker patches such as melasma, freckle, lentigens, nevus Hori (oestrogen hormone disorder) and xanthochromism. When there is too little pigment like the lighter patches such as vitiligo, albinism.

 

Here, we are totally concerned with the hyperpigmentation.

 

Hyper pigmentation is the darkening of an area of skin or nails caused by increased melanin.

 

 

Uneven Skin Tone Face: Remenber than UVA and UVB of sun ray is the main causative factor for pigmentation disorder. It stimulates melanin pigment synthesis.  Tyrosinase is the main enzyme involved in the metabolic pathway.  Any ingredient that can block tyrosinase will be effective treatment agent.

Causes

  • Sun damage. Hyper-pigmentation disorder is caused by sun damage. Example is lentigines lesion.
  • Skin insult from offending cosmetic, chemical, pollution or
  • Hormonal. Estrogen and progesterone surge during pregnancy causes melasma. OCP, hormonal therapy also causes pigmentation.
  • Infection and inflammation. Acne eruption and infection are some of the commonest causes.
  • Genetic. Some problems of pigmentation runs in family.
  • Ethnicity. Darker skin people, Asian, Mediterranean, African are more prone to the disorder.
  • Allergy like eczema.
  • Systemic allergy like those having asthma and hay fever have higher tendency to get blemishes.
  • Laser stimulation can cause iatrogenic disorder which is common among those seeking beauty treatment
  • Chemical peel. Poor post peel care is responsible. There is downtime where post inflammatory hyper-pigmentation (PIH) is common before fully recovers.

The bottom line is excess melanin pigment formation, which can occur in an irregular manner. The lesion can be small focal area, spread diffuse area, well or ill-defined border, superficial on the epidermis or deep into the dermis, the true skin layer. UVA and UVB are the culprit and responsible to stimulate pigment production.

Acne eruption cause causes irritation and PIH with discoloration after acne healed.

 

Hyper pigmentation disorder occurs with a number of diseases such as:

  • Addison’s disease and other sources of adrenal insufficiency. Here, the hormones that stimulate melanin synthesis, such as melanocyte-stimulating hormone (MSH), are frequently elevated. The consequence is pronounced melanin production.
  • Acanthosis nigricans – this is the hyperpigmentation of intertriginous areas, the various skin folds of the joint associated with insulin resistance. So it is very common among the diabetes sufferer. In the early stages, if the blood sugar is well controlled, the problem is reversible.

 

  • Cushing’s disease or other excessive adrenocorticotropic hormone (ACTH) production. This is because MSH production is a by-product of ACTH synthesis from proopiomelanocortin (POMC). Cushing disease sufferer has darker skin color.
  • Linea nigra – a hyperpigmented line found on the abdomen during pregnancy. It is located right at the midline of the abdomen. It appears as darkish brown line.
  • Exposure to certain chemicals such as salicylic acid, bleomycin, and cisplatin.
  • Melasma, which is very common among middle aged Asian lady, also known as chloasma – patchy hyperpigmentation often found in pregnant women. There are shallow and deeper melasma. It usually appears as patchy with ill-defined edges.
  • Smoker’s melanosis. This occurs over the lips. The lips get discoloured dark.
  • Tinea fungal infections such as ringworm can cause pigmentation due to the itch and irritation.
  • Haemochromatosis – this is a common but debilitating genetic disorder characterized by the chronic accumulation of iron in the body. The skin appears discoloured dark.
  • Mercury poisoning – particularly cases of cutaneous exposure resulting from the topical application of mercurial ointments or skin-whitening creams. This occurs commonly in the lower class group of people using cheap illegal skincare.
  • Grave’s disease, is a thyroid disorder. 
  • As a result of tinea cruris, occurring around the hip, inguinal area.

Hyperpigmentation can sometimes be induced by dermatological laser procedures.
