The Truth Untold By Trending Brands: Is Your Eyelash Serum Bad For Your Health?

Thick, fluttery lashes, feminine and divine. It’s one timeless beauty goal that isn’t going away anytime soon. It’s also inspiring many to reach for the latest trending eyelash serums, often marketed as the “natural” or “naked” alternative to mascara and false lashes. However, what’s deemed “natural” isn’t always healthy, as this article will uncover. And with prostaglandins among the top contentious ingredients, we ask the question: What is really the secret behind these rapidly elongated lashes the influencers are so quick to push in our faces?
Beauty or burden - what are prostaglandins in eyelash serums?
Although prostaglandins are naturally occurring lipid compounds in the body and important in regulating processes such as inflammation and blood flow, their accidental discovery in promoting hair growth propelled them into the beauty industry, potentially at the cost of consumer health.
These prostaglandins have been used in glaucoma medications dating back to 1996 . In such a setting, they work to reduce intraocular pressure associated with glaucoma.
In other settings, such as trending beauty products, their outcome for health is perhaps still yet unclear.
The risks of prostaglandins in eyelash serums
Prostaglandins’ benefits can feel enticing, almost like a quick biohack for enviable lashes. But, be warned, it may come at several costs:
- Irritation and sensitivity: Many users report redness, itching, and discomfort around the eyes. For some, this side effect escalates to dryness or swelling.
- Skin darkening: Eyelid hyperpigmentation is a documented concern, often requiring months to reverse, if at all.
- Permanent iris changes: Studies have noted prostaglandins’ potential to darken the iris permanently, especially in light-eyed people. This phenomenon is known to be irreversible.
- Unintended hair growth: The hair-stimulating properties of prostaglandins can lead to unwanted growth in areas they accidentally contact, such as the cheeks or temples.
- Fat loss around the eyes: Known as prostaglandin-associated periorbitopathy, this side effect creates a sunken-eye appearance, adding years to a face.
Why are prostaglandins still used in the beauty industry?
Safer alternatives to prostaglandins in lash serums
That said, the desire for boosted lashes doesn’t always have to come with a compromise. Innovations in naturally sourced (non-prostaglandin) ingredients offer solutions away from the health hazards.
This serum offers more than just hydration—it actively supports skin renewal. Rosehip oil, naturally high in vitamin A, boosts cell turnover, which not only evens out skin tone but may also promote a healthier, stronger lash line. Alongside Japanese rice bran oil and calcium ketogluconate, this blend works to smooth fine lines and deeply hydrate, leaving your skin refreshed and resilient.
Specifically crafted for delicate areas, this serum is packed with natural ingredients that soothe, hydrate, and restore. The gel-to-balm texture absorbs quickly, while antioxidants and plant extracts support eye health by reducing puffiness and targeting dryness. For those looking to protect and promote strength of the skin around their eyes, this product delivers visible care and revitalisation.

How to naturally boost lash health
- Remove makeup gently: Vigorous scrubbing can weaken lash roots; always use a mild remover.
- Incorporate lash-friendly oils: Castor and coconut oils provide hydration and strengthen lashes naturally.
- Follow a lash-promoting diet: Nutrients like biotin, omega-3s, and zinc play a role in hair health.
- Brush lashes regularly: A clean spoolie can stimulate follicles and remove debris.
- Avoid eyelash extensions: Prolonged use can damage natural lashes.
- Limit harsh products: Chemicals in some mascaras and removers can weaken lashes over time.
- Natural and gentle exfoliation: Regularly exfoliating the brow area removes dead skin cells and promotes healthier hair growth.
- Stay hydrated: Proper hydration supports overall hair and skin health.
While prostaglandins may seem like the fast track to dreamy lashes, their risks warrant caution.
