Summary
Active photoprotection utilizes DNA-repair enzymes and antioxidants to prevent and reverse UV-induced skin damage. This approach moves beyond traditional filters for comprehensive skin health.
Area of Science:
- Dermatology and photobiology, focusing on skin health and radiation effects.
Background:
- Ultraviolet radiation (UVR) causes significant skin damage, including DNA alterations and increased cancer risk.
- Current sunscreens primarily use filters, offering limited protection against cellular damage post-exposure.
Purpose of the Study:
- To review the advancements in "active photoprotection" strategies.
- To assess the efficacy of DNA-repair enzymes and antioxidants in combating UVR damage.
Main Methods:
- Comprehensive literature review of scientific data.
- Analysis of clinical trials and in vivo studies on active photoprotection agents.
Main Results:
- DNA-repair enzymes and antioxidants show promise in preventing and reversing UV-induced cellular damage.
- Active photoprotection represents a significant advancement over conventional UV filters.
Conclusions:
- Active photoprotection offers a dual approach to skin protection by repairing existing damage and preventing further harm.
- Further research and clinical application of these agents are warranted for enhanced photoprotection.

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...

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.

02:25Overview of DNA Repair
30.9K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

02:37DNA Damage can Stall the Cell Cycle
9.1K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
