UVA1 exposures change gene expression and circadian time-related protein CRY2 in human skin

Low-dose UVA1 exposures caused changes in gene expression, P53 and CRY2 protein production, and cell type fractions in the skin, but the effects did not reach the subcutaneous adipose tissue. Since the solar UVR dominates in UVA, it is essential to continue to protect the skin from harmful solar agents, regardless of the diurnal preference.
