Grande Lash.

What the gurus are saying

Experts who reviewed Grande Lash found that it does work to thicken and lengthen lashes, but the catch is significant: the product contains a prostaglandin analog, an active ingredient linked to irritation, hyperpigmentation around the eye, color changes to the iris, and potential hollowing of the under-eye area. That means anyone considering it needs to read the full ingredients label carefully, because these compounds are often not clearly marked on the box itself. The FDA has issued warning letters to the brand for lack of transparency, and there have been class action lawsuits. Those aware of and willing to accept these risks may see results, but most experts suggest thoroughly weighing whether the lash gains are worth the potential downsides.
