What Are Prostaglandins in Lash Serums?
Prostaglandins are a class of naturally occurring fatty acids that are present in nearly all bodily tissues. In addition to their physiological roles in inflammation, blood flow regulation, and cell growth, they are commonly used in eyelash serums, which are designed to promote hair growth. However, they have recently gained a lot of attention on social media sites and online forums, where users are complaining that using serums containing prostaglandins has left them with dry eyes, styes (from clogged oil glands), hyperpigmentation around the lash line and on the eyelids, and even discoloration in the iris.
If you care about your eye color, avoid serums containing prostaglandins.
Prostaglandin is a common ingredient found in many eyelash growth serums, known for promoting lash growth but often accompanied by unwanted side effects. However, Shigeru Eyelash and Brow Growth Serum offers a safer alternative.
Our serum, crafted from years of expertise in lash enhancement, is completely Prostaglandin-free and enriched with natural ingredients. It’s the perfect solution for those who want to achieve fuller, healthier lashes and brows without compromising on safety. Choose Shigeru for visibly longer lashes and brows with the power of nature.
Why Many People Avoid Prostaglandin Lash Serums
Over the last few years, prostaglandin-based lash serums have come under heavy discussion across U.S. beauty forums, Reddit threads, TikTok, and skincare communities. While some users do see fast lash growth, others report side effects that made them stop using these formulas altogether.
Commonly reported concerns include:
-
Dry or irritated eyes after regular use
-
Redness or sensitivity along the lash line
-
Styes caused by clogged oil glands
-
Darkening of the skin around the eyes (hyperpigmentation)
-
In rare cases, noticeable changes in iris color
Not everyone experiences these side effects, but the risk varies by individual, especially for people with sensitive eyes or those using lash serums daily for long periods.
This growing awareness is exactly why more consumers now search specifically for a lash serum without prostaglandin or a non prostaglandin eyelash serum. The goal isn’t just longer lashes—it’s peace of mind.
If you care about long-term eye comfort and maintaining your natural eye appearance, avoiding prostaglandin-based formulas is a decision many users feel more confident about.

Why More Users Are Switching to Prostaglandin-Free Lash Serums
For most people, the switch isn’t about chasing trends—it’s about confidence and control.
Many users start with prostaglandin-based serums hoping for fast growth, but over time they begin to question whether the trade-off is worth it. Eye discomfort, fear of pigmentation, and concerns about long-term use often push people to look for a lash serum without prostaglandin that feels safer for everyday application.
What users actually want is simple:
-
A formula they can apply daily without anxiety
-
Something gentle enough for long-term use
-
Visible improvement without worrying about side effects around the eyes

A lash growth serum without prostaglandin fits that need perfectly: no hormone-like ingredients, fewer concerns, and results that build naturally over time.
How Prostaglandin-Free Lash Serums Work (Ingredient Breakdown)
A lash serum without prostaglandin doesn’t force growth. Instead, it focuses on supporting the natural lash cycle—strengthening lashes at the root, reducing breakage, and improving overall lash health so they can appear longer and fuller over time.
Here’s what actually makes a non prostaglandin eyelash serum effective:
Peptides
Peptides help support the lash structure by conditioning the hair fiber and improving resilience. Stronger lashes break less, which is why consistent use often leads to a fuller lash line over time.
Amino Acids
Amino acids are the building blocks of hair. In a lash growth serum without prostaglandin, they help nourish lashes and support healthier-looking growth without aggressive stimulation.
Botanical Extracts
Plant-based ingredients help condition and protect lashes, keeping them soft, flexible, and less prone to brittleness. This is especially important for people who wear makeup or lash extensions regularly.
Hydrating & Conditioning Agents
These ingredients keep lashes moisturized, which improves comfort and reduces dryness around the lash line—one of the main reasons users switch away from prostaglandin-based formulas.
The key difference:
Prostaglandin serums push lashes to grow faster.
Prostaglandin-free serums help lashes stay healthier for longer, allowing natural growth to show more clearly.
That’s why many people looking for the best lash growth serum without prostaglandin prioritize ingredient quality over speed.
