What the lash growth serum label states, omits, and the risks it covers
Is lash growth serum safe for everyday use?
If you stick to the label, this serum is positioned as safe for daily use. You shake the bottle, apply short strokes to the upper lash line and brows on clean skin, and let it dry before using any other products. Do this twice a day for results in 4–6 weeks (sometimes 4 weeks per the company).
Main active ingredients:
- Human stem cell conditioned media (claimed to thicken and strengthen hair)
- Panthenol
- Biotin
- Ocimum basilicum hairy root culture extract
- Extras: aloe, glycerin, niacinamide, sodium hyaluronate, caffeine, tocopherol, and stabilizers
The serum is made in the USA, uses ethically sourced stem cells, and isn’t tested on animals. The brand highlights what it leaves out: mineral oil, parabens, sulfates, phthalates, urea, DEA, and TEA. If you have sensitivities, you’ll need to scan the full list.
Key warnings:
- Never get it directly in your eyes. Slight burning can happen.
- Stop using it immediately (and do not resume) if you develop irritation.
- No information is given about allergies, chronic eye conditions, severe reactions, or long-term effects.
For anyone asking which lash serum is best, this one answers concerns about prostaglandins and heavy-duty additives. But it won’t give you guarantees on uncommon reactions or situations outside standard use.
The bottle holds 0.1 fl. oz. You can recycle the packaging. Using their Eye/Lash Cream on top (after the serum dries) is suggested for extra conditioning. Consistency is key for results, and the same formula works for both lashes and brows, solving “which is best for both” in one go. The safety stops where the stated instructions end.

Can you use lash growth serum when pregnant?
The company does not provide any information about using this lash growth serum during pregnancy. There are no claims of it being pregnancy-safe, nor any warning against use. Just silence.
Facts relevant to pregnancy review:
- Prostaglandin free (these are often not recommended during pregnancy elsewhere)
- No eye color change risk
- Same application/drying steps as for any user
- Warnings to avoid eye contact and stop if irritated
- “Free from” list covers parabens, sulfates, phthalates, etc.
Ingredients include plant root extract and stem cell media, but the manufacturer says nothing about their safety in pregnancy. Application steps do not address hormonal shifts or changes in skin/eye sensitivity that can happen in pregnancy.
In short: There are no pregnancy safety claims here. You must check with your healthcare provider and bring the full ingredient list with you if you’re considering use.
Is eyelash growth serum safe for your eyes?
This serum is positioned for use on both lashes and brows, but the guidelines don’t differ for each area. Application is still to clean skin, only to the upper lash line (and brows), with a warning not to get serum in the eye. Dry completely before layering other products.
- Formula remains prostaglandin free, so it won’t discolor your eyes.
- Human stem cell conditioned media is the foundation.
- Other included ingredients: panthenol, biotin, basil root extract, aloe, niacinamide.
There’s a repeated caution on irritation: avoid eye contact, stop immediately if any issues arise. The label says nothing about risks with long-term daily use, existing eye problems, or how sensitivity might differ for lashes vs. brows.
That’s why this serum lines up with those looking for a prostaglandin-free, “clean” formula, but it doesn’t answer every “what if” related to rare or medical eye issues.
Who shouldn't use it / Limitations
- Anyone who develops irritation from the serum (stop using it right away)
- People seeking guidance for pregnancy or breastfeeding (company says nothing here)
- Those with chronic eye conditions, allergies to listed ingredients, or compromised skin (no guidance provided)
- No claims about severe or long-term risks

Verdict
Factor Five Lash/Brow Growth Serum fits a narrow, clearly defined use: prostaglandin-free boosting of lashes and brows for those sticking closely to the label’s advice. It delivers visible thickening in as little as four weeks for some users, but only within its basic safety claims. Issues of pregnancy, chronic conditions, and rare reactions are unaddressed.
If you’re outside the “healthy adult following directions” group, the lack of extended safety information means you should get medical input. If you fit the category and want a simple, prostaglandin-free serum, the facts on the label back it up. Always start small and watch for how your skin and eyes react.
