MD Lash Factor
What is MD Lash Factor and what does it do?
MD Lash Factor is a physician-formulated eyelash conditioner designed to enhance the appearance of longer, thicker, and fuller-looking lashes. Clinically tested and ophthalmologist-reviewed, this peptide-rich lash serum helps revive lash density and volume, typically within 4 to 6 weeks of daily use.
How do I apply MD Lash Factor correctly?
Apply once nightly to clean, dry skin after removing makeup. Using the applicator brush, draw a thin line along the upper lash line (like applying liquid eyeliner).
- Do not apply to the actual lashes.
- One dip is enough for both eyes.
Can I use MD Lash Factor more than once per day for faster results?
No. One daily application is all you need. Using it more frequently will not improve results and may increase the chance of irritation.
Can I continue using my regular skincare products with MD Lash Factor?
Yes! MD Lash Factor works well alongside your existing skincare regimen. Just ensure it's applied to clean skin before applying other products.
Can I use MD Lash Factor on my eyebrows?
Absolutely. MD Lash Factor is also safe and effective as a brow growth serum, helping sparse or over-plucked brows appear denser, darker, and more defined.
Is MD Lash Factor safe for use with permanent makeup?
Yes. MD Lash Factor can be applied safely over areas with permanent eyeliner or microblading. It will not alter pigment color or cause fading.
Are there any safety studies on MD Lash Factor?
Yes. An independent clinical study by a board-certified ophthalmologist showed no effect on visual acuity, cornea, eyelids, or conjunctiva. There were also no adverse effects on contact lenses.
Can MD Lash Factor cause irritation or allergic reactions?
While most users report no irritation, some may experience mild redness or tingling at the lash line. If this occurs:
- Pause use for a few days
- Resume with a smaller amount
- Discontinue entirely if symptoms persist
As with any cosmetic, avoid use if you're allergic to any listed ingredients.
Once I see results, do I need to keep using MD Lash Factor every night?
No. Once your lashes reach the desired appearance, reduce to 2–3 times per week to maintain results. Discontinuing use entirely will gradually return lashes to their original length and fullness.
Who should not use MD Lash Factor?
MD Lash Factor is not recommended if you:
- Have had eye surgery in the past 6 months
- Have an active eye infection
- Using prescription eye medications (consult your doctor first)
Can both men and women use MD Lash Factor Eyelash Conditioner?
Yes. MD Lash Factor is suitable for adult men and women (18+) and is safe for all skin types.
Do eyelashes grow back naturally?
It depends on the cause. If thinning is due to age, stress, lash extensions, or cosmetic damage, eyelash conditioners like MD Lash Factor can support the appearance of fuller-looking lashes over time.
Can I still use lash curlers or mascara with MD Lash Factor?
Yes, once your lashes become naturally stronger and longer, many users find they rely less on curlers or extensions. Always apply MD Lash Factor on clean lashes before other products.
How long is MD Lash Factor good for after opening?
Use within 6 months of opening, as with any eye-area cosmetic product.
Can I use MD Lash Factor while wearing lash extensions?
Yes. Apply to the base of your upper lashes daily, being careful not to disturb extensions.
Can I use MD Lash Factor if I am pregnant or breastfeeding?
This product has not been tested on pregnant or breastfeeding individuals. Consult your physician before use.
What makes MD Lash Factor unique?
It features a patented formula developed by physicians and supported by peer-reviewed research for safety and visible improvement in lash appearance.
