You’re on your nightly skincare routine, applying your favorite eyelash serum, dreaming of longer, fuller lashes—when suddenly, you notice darker under-eye circles. Coincidence? Or is your eyelash serum the culprit?
Most lash serums look innocent enough, but some contain powerful active ingredients originally found in prescription treatments for glaucoma. One major ingredient to watch for: prostaglandin analogs. These can stimulate lash growth—but they might also cause hyperpigmentation around the eyes, leading to dark circles or redness.
This pigmentation happens because prostaglandins can increase melanin production in the skin. Since the area around your eyes is delicate and thin, any discoloration becomes noticeable fast.
Not all lash serums are made equal. While some formulas use peptides, biotin, or plant extracts and don’t tend to cause discoloration, those with prostaglandin analogs are more likely to darken the skin. Here’s a quick breakdown:
| Type of Serum | Common Ingredients | Risk of Dark Circles |
|---|---|---|
| Prostaglandin-based | Isopropyl Cloprostenate, Bimatoprost | High |
| Natural/Peptide-based | Biotin, Peptides, Castor Oil | Low |
Still hooked on your lash serum? No problem—just be smart about how you apply it. Avoid getting the serum on the skin under your eyes; apply only to the lash line using a thin brush. Many dermatologists recommend wiping away excess product to prevent seepage and choosing formulas without prostaglandins if you're prone to hyperpigmentation.
Also, consistency matters. If discoloration begins to appear, stop using the product and consult a dermatologist. In some cases, the pigmentation fades after discontinuing use, but that's not always guaranteed.

Yes, some eyelash serums can cause dark circles as a side effect. Certain ingredients, like prostaglandin analogs, are known to sometimes darken the skin around the eyes. It's important to patch test and read product labels to ensure safety.
To reduce dark circles caused by eyelash serum, discontinue use of the product causing the issue. Use a gentle eye cream with brightening ingredients like vitamin C or caffeine. If symptoms persist, consult a dermatologist for further advice.
Dark circles caused by eyelash serums are usually temporary and should fade over time once you stop using the product. However, in rare cases, prolonged use might cause more persistent pigmentation changes.
Common side effects of eyelash serums may include eye irritation, redness, dark circles, and in rare cases, changes in eye color or loss of under-eye fat. Always follow application instructions to reduce the risk.
To safely use an eyelash serum, apply it only to the upper lash line with a clean applicator. Avoid contact with your skin or eyes, and use the product as directed. Consult a professional if you notice any adverse effects.
