Are You Risking Your Eye Health for Longer Lashes?

If you use an eyelash serum, you might be putting your eyes at risk. The culprit? A hormone called Prostaglandin, which is found in many of today's most popular eyelash growth products.

What is Prostaglandin?

Prostaglandin is a hormone found in the body that helps things like inflammation and blood clotting. However, many eyelash serums use a man-made version of the hormone to make your eyelashes appear longer and fuller.

Why You Should Avoid

While the lash-enhancing effects of Prostaglandin seem appealing, a growing body of research suggests that this hormone may cause a range of alarming side effects:

Eye Irritation

Many users of prostaglandin-based eyelash serums report experiencing redness, itching, and inflammation around the eyes.

Eyelid Darkening

Prostaglandin has been shown to cause hyperpigmentation, or darkening of the skin, particularly on the eyelids.

Eye Color Changes

Perhaps most concerning, some studies have found that prostaglandin analogs can cause permanent changes in eye color.

Other Side Effects

Additional side effects of prostaglandin include blurred vision, eyelid swelling, and even unwanted hair growth around the eyes.

These adverse effects have left many women searching for a safer alternative that still delivers the results they desire.

Instead, Diablo's eyelash serum harnesses the power of peptides, vitamins, and growth extracts to nourish and strengthen lashes, promoting natural, healthy eyelash growth without the potential risks.
