Traits - Skin youthfulness

Skin aging is studied in research using microtopography (fine wrinkles, surface roughness) and other measurable skin features that change with age and sun exposure.
GWAS work has identified variants near pigmentation, collagen, and DNA-repair genes linked to differences in visible skin aging.
This result reflects research-level variation in skin-aging traits and is not a forecast of how youthful skin will look.
Sun exposure, smoking, sleep, hydration, skincare, hormones, and overall health are major drivers of how skin actually ages over time.

DNA Genics reports genotypes based on the 'positive' strand of the human genome reference sequence (build 37/HG19). Other companies may use the opposite strand, so genotypes may need conversion for comparison.
The following peer-reviewed scientific studies support the genetic associations analyzed in this report.
