Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview01:02

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

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 electronic transitions. As a result...
UV–Vis Spectroscopy of Conjugated Systems01:32

UV–Vis Spectroscopy of Conjugated Systems

Organic compounds with conjugated double bonds show strong absorption features in the UV–visible region of the electromagnetic spectrum attributed to π → π* electronic excitations. Generally, a UV–vis absorption spectrum is recorded as a plot of absorbance vs wavelength. The wavelength of maximum absorbance, which manifests as a peak in the absorption spectrum, is denoted as λmax.
One of the factors influencing λmax is the extent of conjugation in the...
Photoreceptors and Plant Responses to Light02:00

Photoreceptors and Plant Responses to Light

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.
Energy Transfer in Chemical Reactions01:16

Energy Transfer in Chemical Reactions

Chemical reactions require sufficient energy to cause the matter to collide with enough precision and force that old chemical bonds can be broken and new ones formed. In general, kinetic energy is the form of energy powering any type of matter in motion. Imagine a person building a brick wall. The energy it takes to lift and place one brick on top of another is the kinetic energy—the energy matter possesses because of its motion. Once the wall is in place, it stores potential energy. Potential...
UV–Vis Spectroscopy: Molecular Electronic Transitions01:16

UV–Vis Spectroscopy: Molecular Electronic Transitions

In Ultraviolet–Visible (UV–Vis) spectroscopy, the absorption of electromagnetic radiation is used to probe the electronic structure of molecules. This technique provides insights into molecular electronic transitions, particularly the movement of electrons between different molecular orbitals. Radiation is absorbed if the energy of the electromagnetic radiation passing through the molecule is precisely equal to the energy difference between the excited and ground states. During this process,...

Area of Science:

  • Dermatology and cosmetic science.
  • Photobiology and photochemistry.
  • Environmental science and toxicology.

Background:

  • Traditional photoprotection focused on UVB and UVA radiation.
  • Emerging evidence implicates long-wavelength UVA1 (LW-UVA1) and visible light (VL) in skin damage.
  • LW-UVA1 and VL contribute to pigmentation, erythema, and photoaging.

Purpose of the Study:

  • To review recent advances in LW-UVA1 and visible light photoprotection.
  • To discuss emerging UV-filter formulations and non-filtering protective ingredients (PINGs).
  • To explore personalized photoprotection, skin microbiome, and environmental considerations.

Main Methods:

  • Literature review of PubMed and Google Scholar.
  • Screening for studies on LW-UVA1 and VL photoprotection.
  • Narrative synthesis of findings without formal quality assessment.

Main Results:

  • LW-UVA1 and VL have synergistic effects causing erythema and pigmentation.
  • Innovations include tinted mineral sunscreens, broader-spectrum UV filters (Mexoryl 400, TriAsorB), and oral/topical PINGs.
  • Skin microbiome and personalized approaches are emerging areas; environmental concerns persist.

Conclusions:

  • Photoprotection is broadening to cover LW-UVA1 and VL with new technologies.
  • Innovations improve UV protection but raise environmental and safety questions.
