Positive Impact has launched an opto-cosmetic, restorative serum for the loss of eyelashes and eyelash conditions that can result from long-term dry eye disease, meibomian gland dysfunction and blepharitis.

The Lash Builder serum was developed by optometrist Craig Wilcox, who also created the foaming DemEx cleanser, for use in his specialist dry eye practice. It was formulated to be free from harsh ingredients that exacerbate dry eye symptoms and contains no formaldehyde-releasing ingredients and no parabens.

The formulation contains active ingredients that are said to impact eyelash loss and support new growth, including red clover extract, which is rich in isoflavones and a biomimetic peptide, acetyl tetrapeptide 3, which helps promote stronger hair follicles.
