MD Lash Factor® Eyelash Conditioner

Physician-Invented | Patent-Backed | Ophthalmologist-Tested

MD Lash Factor® is the original physician-formulated eyelash conditioner, developed by Dr. Susan Lin, M.D. Protected by US Patent 8,206,695, it is built around dechloro ethylcloprostenolamide, a cosmetic-grade prostaglandin analogue developed by Dr. Lin. It contains no prostaglandin analogue used for the treatment of glaucoma — no bimatoprost, travoprost, latanoprost or unoprostone — and no prescription drug of any kind.

Why Doctors Choose MD®

• Measured in a published trial: in a randomized, double-blind, placebo-controlled clinical study, four weeks of nightly use produced statistically significant increases in eyelash length of 42% to 53% across the active groups, against 20% for placebo. All patients reported an improved appearance in the length of their lashes. Lash length was measured with microcalipers to 0.1 mm at six locations per eye, by technicians blinded to treatment assignment.
• Examined by an ophthalmologist: in an independent four-week ocular safety evaluation of 35 subjects under Institutional Review Board oversight, there were no clinically significant changes in visual acuity, tear film break-up time or intraocular pressure, and no corneal abnormalities or superficial punctate keratopathy on slit lamp examination.
• Suitable for contact lens wearers: that study included contact lens wearers, non-wearers and people with self-assessed sensitive eyes, with no changes in contact lens colour, scratches or deposits after four weeks of use.
• Tested for tolerance: a repeat insult patch test in 209 subjects found no clinically significant potential for dermal irritation or sensitization. Independently assessed as non-cytotoxic, non-sensitising and non-mutagenic.
• What to expect: some users notice mild irritation when starting. In our published trial this was transient and typically resolved within a few days of continued use. Apply one stroke along the upper lash line — more is not better.
