Summary
Sunscreen is crucial for photoprotection against UV damage. This review details sunscreen ingredients, efficacy, and use in diverse populations, including children and skin of color.
Area of Science:
- Dermatology
- Photobiology
- Cosmetic Science
Background:
- Ultraviolet (UV) radiation causes significant skin damage, including sunburn, photoaging, and skin cancer.
- Sunscreen is a primary tool for mitigating UV-induced harm.
- Evolving knowledge necessitates a review of sunscreen's role and application.
Purpose of the Study:
- To review sunscreen active and additive ingredients, their mechanisms, and coverage limitations.
- To assess sunscreen efficacy against various UV-related conditions.
- To provide guidance on sunscreen use for children and individuals with skin of color.
Main Methods:
- Literature review of sunscreen properties and efficacy studies.
- Analysis of mechanisms of action for sunscreen ingredients.
- Synthesis of data on photoprotection endpoints.
Main Results:
- Sunscreen effectively protects against sunburn, photocarcinogenesis, and photoaging.
- Gaps in UV coverage by current sunscreens exist.
- Specific considerations are needed for pediatric and diverse skin types.
Conclusions:
- Sunscreen is essential for comprehensive photoprotection.
- Understanding ingredient properties and application is key to maximizing efficacy.
- Tailored sunscreen selection and use are important for all individuals, especially children and those with skin of color.

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.

01:30Skin Cancer
4.1K
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.

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

02:37The Electromagnetic Spectrum
52.8K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

01:14Changes in Skin Color: Clinical Perspectives
2.0K
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.
