Summary
Leptin, a metabolic hormone, shows potential in improving skin regeneration, hair growth, and reversing skin aging. Its effects on mitochondria and cell proliferation suggest significant dermatological applications.
Area of Science:
- Dermatology
- Endocrinology
- Molecular Biology
Background:
- Leptin is an adipokine with known metabolic functions.
- Its role in skin biology and pathology is increasingly recognized.
Purpose of the Study:
- To review current evidence supporting leptin's role in mammalian skin.
- To explore the potential of leptin and its mimetics in dermatology.
Main Methods:
- Review of existing scientific literature on leptin's effects on skin.
- Analysis of leptin's signaling pathways involved in skin processes.
Main Results:
- Leptin enhances mitochondrial activity and biogenesis, aiding wound healing and hair growth.
- Leptin signaling pathways (JAK2/STAT3, AMPK, PPAR) promote cell proliferation and metabolic activation in skin.
- Leptin may reverse aspects of skin aging.
Conclusions:
- Leptin and its mimetics hold significant potential for improving skin regeneration, hair cycling, and anti-aging therapies.
- Further investigation into leptin's dermatological applications is warranted.

01:14Changes 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.

01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:27Acne 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...
01:30Skin 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.
