It’s no secret that UVB radiation from the sun causes wrinkles. However, a recent Japanese study published in the American Journal of Physiology — Regulatory, Integrative and Comparative Physiology indicates that oxygen may help combat the formation of wrinkles by lessening tissue damage done by UVB rays.
In the study (S. Kawada, M. Ohtani, N. Ishii. Increased oxygen tension attenuates acute ultraviolet-B-induced skin angiogenesis and wrinkle formation. AJP: Regulatory, Integrative and Comparative Physiology, 2010; DOI:), mice who were placed in an oxygen chamber after exposure to UVB radiation developed fewer wrinkles and showed fewer signs of tissue damage than mice who were exposed to UVB radiation alone.
