Happylogy Glowing First Wrinkles Age-Defying Care
You are never so glowing as when you are happy. The feeling of happiness stimulates the release of endorphins into the skin and triggers a series of responses. Your skin appears plump, smooth and luminous: the three characteristics of young and radiant skin.
Guerlain has created the HAPPYLOGY line, whose unique complex stimulates the release of endorphins* and recreates the effects of happiness on the skin.
