We're not so sure. Consumer Reports (which doesn't accept advertising, and tests cars and other consumer products) featured lash growth products in a "Bad Beauty Deals" section.
"Lash-growth products are regulated as drugs by the FDA and must be subject to approval," said John E. Bailey, chief scientist at the Personal Care Products Council, in the article.
