PROBLEM TO BE SOLVED: To provide a novel compound exhibiting, despite having a low melting point, compatibility with various cosmetic bases, absorbing rays over nearly entire regions of UV-A and UV-B, excellent in terms of light stability, exhibiting long-term decomposition resistance and degradation resistance due to both an ultraviolet absorption function and a matrix metal proteinase (MMP) inhibition activity function inherent in the compound, and usable as a hybrid material for doubly protecting skin from aging damages and effective components of skin external preparations useful as MMP inhibitors and having scarce side effects.SOLUTION: The provided 2-(2,4-dihydroxyphenyl)-2H-benzotriazole derivative is expressed by the following general formula 1. |
