Ultraviolet (UV) rays have been identified as a carcinogen with long-term irradiation and are an important risk factor for skin cancer. Here, we report the use of optical coherence tomography/optical coherence tomography angiography (OCT/OCTA) to study acute UV-induced effects on skin in vivo. To understand the relationship between the acute effects and irradiated UV power density, three groups were irradiated with different power densities in our experiments. Furthermore, the same skin area was repeatedly scanned with OCT during UV irradiation to investigate the progress of the induced acute effects and after irradiation for observation of skin recovery. Subsequently, the OCT/OCTA results were quantitatively analyzed to acquire skin thickness and blood-vessel density for comparison. UV-induced acute effects on morphology and microcirculation can be identified from OCT/OCTA results, which showed the increases in the skin thickness and blood-vessel density and even severe damage types such as blisters. The results of quantitative analyses also illustrated that the severity of damage induced by UV irradiation can be distinguished and the skin recovery can be monitored with OCT. Our results indicate that OCT can be a promising tool for early detection of UV-induced acute skin damage.
