Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
Pharmaceutical Poisoning: Treatment Strategies01:26

Pharmaceutical Poisoning: Treatment Strategies

Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...

Area of Science:

  • Dermatology
  • Cosmetic Science

Background:

  • Hyperpigmentation disorders are common skin conditions.
  • Acquired disorders, including melasma and postinflammatory hyperpigmentation, have multifactorial causes.
  • These conditions often affect individuals with darker skin phototypes.

Purpose of the Study:

  • To review the treatment of two common acquired hyperpigmentation disorders: melasma and postinflammatory hyperpigmentation.
  • To highlight the challenges and considerations in managing these conditions, particularly in relation to skin phototype.

Main Methods:

  • Literature review focusing on melasma and postinflammatory hyperpigmentation.
  • Discussion of treatment modalities including medical, surgical, and laser therapies.
  • Emphasis on the impact of patient skin phototype on treatment efficacy and safety.

Main Results:

  • Melasma and postinflammatory hyperpigmentation are acquired dyspigmentation disorders.
  • Treatment requires a multimodal approach and patient-physician patience.
  • Skin phototype significantly influences treatment outcomes and risk of adverse effects.

Conclusions:

  • Effective management of melasma and postinflammatory hyperpigmentation necessitates a comprehensive strategy.
  • Patient skin phototype is a critical factor in determining appropriate treatment and managing potential complications.
  • Further research may be needed to optimize treatments for diverse skin types.
