Summary
Human skin requires protection beyond ultraviolet (UV) rays to prevent sun damage. New research explores compounds that shield skin from both UV and near-infrared (NIR) radiation, including infrared A (IRA).
Area of Science:
- Dermatology
- Photoprotection
- Skin Health
Background:
- Human skin faces increasing exposure to diverse solar wavelengths.
- Sun damage extends beyond ultraviolet (UV) radiation to include near-infrared (NIR) energy.
- Comprehensive photoprotection necessitates shielding against the full solar spectrum.
Purpose of the Study:
- To explore novel topical strategies for broad-spectrum sun protection.
- To investigate compounds offering protection against both UV and infrared A (IRA) radiation.
- To advance the development of innovative skincare ingredients.
Main Methods:
- Exploration of new chemical and physical UV filters.
- Identification of molecules that counteract the effects of infrared A (IRA) radiation.
- Evaluation of mitochondrially targeted antioxidants (synthetic and natural).
Main Results:
- Research is actively exploring novel combinations of UV filters and IRA-protective agents.
- Mitochondrially targeted antioxidants are identified as potential infrared-protective agents.
- Development of broad-spectrum photoprotective strategies is ongoing.
Conclusions:
- Complete protection against sun damage requires addressing UV and NIR radiation.
- Innovative research focuses on combining UV filters with IRA-mitigating molecules.
- Future photoprotective agents may include advanced antioxidants for comprehensive skin defense.

01:19Pigmentation
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...

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).

01:21Layers of the Epidermis
The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

01:35Mutations
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
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...

01:18Surface Membrane Barriers
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
