Pigmentation01:19

Pigmentation

3.4K
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...

Mutations01:35

Mutations

41.4K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Skin Cancer01:30

Skin Cancer

4.9K
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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

6.3K
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...

Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

2.6K
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...

Photoreceptors and Plant Responses to Light02:00

Photoreceptors and Plant Responses to Light

26.3K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Area of Science:

  • Dermatology and photoprotection research.
  • Cosmetic science and product development.
  • Public health and consumer education.

Background:

  • Historical use of sun protection methods predates modern sunscreen products.
  • Early 20th-century association of tanned skin with health contrasted with the need to prevent sunburn.
  • Development of the first sunscreen products around 1945 marked a significant advancement in solar radiation protection.

Purpose of the Study:

  • To analyze and discuss current topics and controversies surrounding sun protection products.
  • To examine the evolving perception and intended uses of sunscreens over time.
  • To address the need for consumer and patient information regarding sunscreen efficacy, safety, and application.

Main Methods:

  • Review and discussion of existing literature and regulatory frameworks concerning sunscreen filters and product performance.
  • Analysis of changing consumer perceptions and marketing of sunscreen products.
  • Examination of safety data, including nanoparticulate filters and regulatory issues.

Main Results:

  • Sunscreen product roles have shifted from erythema prevention to skin cancer prevention, and more recently to beauty, lifestyle, and anti-aging benefits.
  • A wide array of sunscreen filters and product formats have been developed, alongside regulatory frameworks and performance metrics.
  • Conflicting areas such as ideal product characteristics, safety concerns, and application in daily life require ongoing investigation.

Conclusions:

  • The multifaceted nature of sun protection products necessitates a comprehensive understanding of their risks and benefits.
  • Continued research and education are vital to address controversies and guide consumers in making informed decisions about UV protection.
