Yes. Like all effective eyelash serums, fLASH contains a type of Prostaglandin which is a conditioning agent for the lashes. The type of prostaglandin used in fLASH only supports locally where it is applied. Unlike hormones, Prostaglandins are only produced locally where they are needed and have a short life span (they’re quickly broken down).
