We hear about lash enhancers all the time whether it be a advertisement in a magazine or a commercial on the television. But the one thing these commercials don't tell you are the major side effects that can come with using their product. Most lash enhancers contain one common ingredient which is prostaglandin. Prostaglandin is an ingredient found in glaucoma medications and has shown major results in helping lashes grow. However, prostaglandins also have some not so pleasant side effects that can include darkening of the iris; this can be severe, sometimes turning blue into brown. Not to mention you can also develop swollen retina, blurred vision, red rings on the eye, itchy eyelids, and other irritation.
