Key Takeaways
- Factor Five Inc publishes no instructions or recipe for homemade lash serums or eyelash growth creams.
- Their Eye/Lash Cream is a 3-in-1 solution, combining actives for the eye area, lashes, and brows in one daily step.
- This commercial formula skips prostaglandins, won’t alter eye color, and is tested for safe everyday use.
- DIY recipes can’t match commercial safety or ingredient accuracy, and there’s no manufacturer-backed guidance for making them.
Commercial Eye/Lash Cream vs. Homemade: What You Actually Get
| Feature | Factor Five Eye/Lash Cream | Homemade Lash Serum |
|---|---|---|
| Key Ingredients | Human stem cell-derived growth factors, biotin, redensyl | No info provided |
| Safety Information | Prostaglandin free, safe for daily use, no eye color change | No info provided |

Commercial formula details vs. no manufacturer data for DIY
Is There Any Way To Make Homemade Lash Serum Safely?
No. Factor Five Inc offers no method or guidance for a safe homemade lash serum. Your only manufacturer-endorsed path is their commercial Eye/Lash Cream.
Why the silence? The area around your eyes has the thinnest, most sensitive skin on your body. Any error, a contaminated formula, the wrong ingredient ratio, can cause irritation or worse. Home concoctions lack controlled formulation, sterile packaging, and safety testing. That’s why Factor Five says nothing about DIY steps. Instead, they focus on a formula that’s been vetted and designed for daily use, using:
- Human stem cell-derived growth factors (supporting skin replenishment)
- Biotin and redensyl for enhancing lashes and brows
- A prostaglandin-free blend, avoiding ingredients known for causing eye color changes
The appeal is obvious: with one container you cover eyes, lashes, and brows, without extra steps or uncertain mixes. Especially for sensitive areas, the difference between “tested” and “unknown” is everything.
Could you try to piece together your own version? In reality, actives like human stem cell-derived growth factors are commercially controlled and not available over the counter. Redensyl and biotin on their own don’t automatically yield the same effect without precise formulation. Lacking manufacturer or scientific guidance at home, it’s guesswork.
Short, efficient routines stand out. This cream fits into your daily habits quickly. Its proven, prostaglandin-free safety profile doesn’t extend to any DIY alternatives, the risks and responsibilities would fall on you alone.
Homemade Serums vs. Commercial Creams (Redensyl Included): What’s the Difference?
The manufacturer makes no claims or comparisons involving homemade serums. Their product, however, is built on a blend of redensyl, human stem cell-derived growth factors, and biotin, all in one, prostaglandin-free cream.
Here’s what that means in practice:
- Commercial lash and brow products, especially those targeting sensitive eye areas, are formulated with precise amounts and tested for consistent results.
- Redensyl is included specifically to support lash and brow fullness, but again, only as part of the controlled, finished mix.
- Homemade attempts invent their own ratios, often with no clear safety, effectiveness, or compatibility information. Factor Five provides zero guidance for DIY.
You get certainty with the commercial product: safe for daily use, no eye color change, and time savings via a 3-in-1 approach. With homemade versions, every important detail is missing. The company supports their finished cream, not home tinkering.
The eye area, in particular, reacts unpredictably to imbalanced mixtures. With Factor Five’s product, the formulation is done for you, with all components working together and the safety statement on record.
Can You Use Lash Serum and Castor Oil Together?
Factor Five Inc offers no statement about using lash serum in combination with castor oil. Their Eye/Lash Cream is designed to be a complete, standalone 3-in-1 product.
No advice is included about mixing in other substances like castor oil, an ingredient many use for its heavy, moisturizing quality. Factor Five’s cream already addresses lash, brow, and eye area enhancement in one application. Its claim to fame is being prostaglandin-free, not causing eye color change, and saving time by condensing your routine.
When it comes to safety, less is typically better near your eyes. Combining untested products, even something as “natural” as castor oil, creates unpredictable interactions that are unstudied by the manufacturer.
If your main concern is getting the best for brows and lashes, the facts stick with the finished cream. Using anything else alongside it isn’t recommended, not because of stated dangers, but because there’s just no guidance offered either way.
How to Make Lash Serum at Home with Vaseline?
There’s no Factor Five-endorsed method for making a vaseline-based lash serum. The company only backs their ready-to-use Eye/Lash Cream, blending advanced actives for this unique use case.
Vaseline is often mentioned in home beauty circles for its occlusive moisturizing qualities. But there’s no connection between this simple substance and Factor Five’s clinical formulation. Their product uses human stem cell-derived growth factors, biotin, and redensyl, and specifically lists prostaglandin-free status and safety for everyday use.
Homemade mixes with vaseline offer no comparable ingredient profile, safety data, or efficiency. The commercial cream’s main selling point? A powerhouse, time-saving treatment for three different targets (eye area, lashes, brows), with one product and no surprises.
If you’re searching for something with proven safety, a vaseline recipe doesn’t match up to the commercial option.
