Summary
New photoprotective compounds were developed to shield skin from high-energy visible radiation (HEVR). These novel sunscreen ingredients offer enhanced absorption, stability, and antioxidant properties, outperforming current HEVR sunscreens.
Area of Science:
- Photochemistry
- Dermatology
- Materials Science
Background:
- High-energy visible radiation (HEVR) poses risks to skin health.
- Existing sunscreens lack effective protection against HEVR.
- Development of novel photoprotective agents is crucial.
Purpose of the Study:
- To design and synthesize novel high-energy visible radiation (HEVR) photoprotectors.
- To evaluate the photoprotective efficacy and properties of new compounds.
- To incorporate and test these compounds in sunscreen formulations.
Main Methods:
- Chemical synthesis of novel HEVR photoprotective compounds.
- Characterization of absorption, solubility, and photostability.
- Formulation of sunscreen preparations with selected compounds.
- Benchmarking against commercial sunscreens and standard formulations.
Main Results:
- Successfully designed and prepared a new family of HEVR photoprotectors.
- Compounds exhibited tunable absorption, solubility, and enhanced photostability.
- Demonstrated significant antioxidant capacity, beneficial for cosmetic applications.
- Sunscreen formulations with these compounds provided superior HEVR photoprotection compared to existing products.
Conclusions:
- Developed effective HEVR photoprotectors with tunable and improved properties.
- These novel compounds offer enhanced photostability and antioxidant benefits.
- The new sunscreen formulations represent an advancement in HEVR protection.

01:19Pigmentation
5.0K
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
8.8K
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...

01:35Mutations
45.6K
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.

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...

01:02Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview
8.6K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for...

01:20Radical Autoxidation
3.4K
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...
