Investigating a potential class action lawsuit against NeuLash for deceptive labeling and unlawful marketing. NeuLash contains isopropyl cloprostenate, an ingredient known to cause significant dry eye disease. NeuLash is not a prescription product and cosmetics oversight regulations in the United States are lax; therefore, the Food and Drug Administration (FDA) has limited involvement. Isopropyl cloprostenate has not been approved by the FDA to be an active ingredient in cosmetic products. If you have purchased NeuLash, please submit your information below.
