A novel peptide ‘T14’ reflects age and photo-aging in human skin

Researchers discovered a novel peptide, T14, that is detectable in human keratinocytes and inversely related to age, with higher levels found in chronically photosensitive individuals. The study suggests that monitoring T14 levels may offer insights into the link between degenerative diseases and epidermal cell profiles.
