In Vivo and In Vitro Evaluation of PTeCA (1H‐Pyrrole‐2,3,4,5‐Tetracarboxylic Acid) in Hair Matrix as a Marker for Oxidative Cosmetic Treatment

Drug Testing and Analysis, Volume 18, Issue 6, Page 739-749, June 2026.
A total of 3378 self‐reported treated and untreated hair samples were analyzed for PTCA and PTeCA by LC‐MS/MS. Moreover, their in vitro formation was assessed in 225 untreated hair by different cosmetic treatments with and without oxidative agents. Data suggest that PTeCA could be a reliable marker for oxidative cosmetic treatments in hair.

Ultrafast dynamics of the eumelanin pigment [PDF]

, 2022
<p><b>Ultraviolet (UV) solar radiation can cause many hazardous effects in human body. It is highly carcinogenic; exposure to the sun radiation is leading to the malignant melanoma – the most aggressive and widely spread skin cancer. Most organic (including bioorganic) molecules can absorb the UV light which leads to the DNA photo-damage ...
