Background: Timosaponin A-III (TA-III) is known to exist in the medicinal herb of Anemarrhena asphodeloides as one of major chemical components.
Aims: The photoprotective properties of TA-III on UVB-exposed HaCaT cells were evaluated on the antiwrinkle effects and skin safety in terms of clinical trial.
Methods: The level of matrix metalloproteinase (MMP)-1, tissue inhibitor of metalloproteinases (TIMPs), and pro-inflammatory cytokines were measured in HaCaT cells following UVB irradiation.
