14 Nov 2022 --- Malaysia-based researchers have found that carrageenans may have a potential photoprotective effect against ultraviolet B (UVB) in keratinocytes – a cell type found in the epidermis. This effect may be due to carrageenans’ antioxidant and anti-inflammatory properties, which may reduce reactive oxygen species (ROS) and inflammatory cytokines and prevent the activation of additional photoaging mediators.
