Usage
It is an antioxidant that is considered effective in influencing the formation of pigmentation, and therefore able to lighten the skin. It is a synthetic compound that is partially derived from natural lightening compounds found in scotch pine bark, and is considered a reliable whitening agent.
According to studies when directly compared to B-Arbutin, Phenylethyl Resorcinol was shown to be over one hundred times as effective at lightening hair, and when tested in vivo on skin that had not been exposed to light, 0.5% concentrations of Phenylethyl Resorcinol proved to be more effective than 1.0% kojic acid.
Storage
It should be sealed and shaded to be stored in a dry, cool, well ventilated place.
