Our Story

Sesha began as a biomedical endeavor over 20 years ago when Harvard and MIT educated scientist, Dr. Dean Hsieh, discovered an alternative to pills or injections to restore the skin's youthful appeal, the Permeation Enhancement Technology (P.E.T.®). During the initial testing phases of this technology, our scientists recognized that P.E.T.® could achieve remarkable results in preventing and restoring damage to the skin.
