Lashes + Brows: Prostaglandins vs. Growth Factors
Lashes + Brows: Prostaglandins vs. Growth Factors
A comparison of GrandeBROW and FACTORFIVE serums
If you’re looking to grow fuller brows or stronger lashes, you’ve likely come across serums with bold promises. But not all formulas are created equal—and how they work matters just as much as the results.
Let’s explore the difference between prostaglandin-based serums (like GrandeBROW) and growth factor-based serums (like FACTORFIVE Lash + Brow Serum and Eye & Lash Cream)—so you can choose what’s right for you.
What Are Prostaglandin-Based Serums?
Think: Bold Results with Potential Sensitivities
Prostaglandins are compounds that influence hair growth cycles. In serums like GrandeBROW, they’re included as analogs (synthetic versions) that extend the growth phase of brow hairs.
What they do:
Encourage longer, fuller, faster-growing brows
Often show results within 4–6 weeks
Can be very effective in the short term
Possible side effects:
Redness, irritation, or skin sensitivity
Skin discoloration near the application area
Unintended hair growth outside target zone
Brittle or overly long hair when overused
Thinning or shedding after stopping use
📝 Note: I carry GrandeBROW for clients who want a boost and don’t experience irritation—but I don’t carry prostaglandin-based lash serums.
What Are Growth Factor-Based Serums?
Think: Gentle, Restorative, Long-Term Support
Growth factors are naturally occurring proteins that support healthy skin and follicle repair. In FACTORFIVE Lash + Brow Serum, they’re ethically derived from human stem cell cultures—designed to work with your body’s natural processes, not override them.
What they do:
Strengthen and condition follicles
Improve brow and lash density
Support hair growth without hormone-mimicking effects
Safe for sensitive skin and long-term use
Offer a subtle, natural enhancement over time
Bonus: The FACTORFIVE Eye & Lash Cream is a multitasking option I love—nourishing the eye area while also supporting lash health.
What I Recommend in Practice
✨ I often suggest a boost-then-maintain approach.
Start with GrandeBROW if you want to kickstart growth and your skin can tolerate it.
Then, switch to either the FACTORFIVE Lash + Brow Serum or Eye & Lash Cream for long-term maintenance and support. These formulas work with your skin—not against it—and offer a softer, more sustainable approach.
Final Thoughts
The goal isn’t just growth—it’s healthy, balanced beauty that respects your skin and delivers results that last. If you’re not sure where to start, we can talk about your goals and sensitivities at your next visit.
