The same physician, the same standard — formulated without prostaglandins. MD Lash Factor® Ultima is the prostaglandin-free member of the MD Lash Factor® family, developed by Dr. Susan Lin, M.D. The Original delivers our clinically measured lash-length results; Ultima is the prostaglandin-free alternative for sensitive eyes and contact lens wearers.
Original and Ultima
MD Lash Factor® comes in two suitability-matched options at the same price. How they differ:
-
Original — the patented formula (US Patent 8,206,695) built around a cosmetic-grade prostaglandin analogue, the formula behind our clinically measured lash-length results.
-
Ultima (this product) — prostaglandin-free, conditioning the lash line through a peptide-and-botanical complex. Formulated for sensitive eyes and situations where a prostaglandin-free choice is preferred.
Who Ultima is for
-
Contact lens wearers and those with self-described sensitive eyes.
- Anyone who has experienced irritation or redness with prostaglandin-based lash products.
- People using prescription eye-pressure (glaucoma) medication — please consult your eye-care professional before use.
- Those who are pregnant or nursing and prefer a prostaglandin-free option — consult your physician before use.
What it does
- Conditions the lash line.
- Contains conditioning peptides and biotin.
- Lightweight, fragrance-free, and gentle enough for daily use along the upper lash line.
Key conditioning actives
-
Biotinoyl Tripeptide-1 & Apigenin — a peptide-and-botanical complex that conditions the lash line.
-
Panthenol, Biotin & amino acids (Acetyl Cysteine, Acetyl Methionine, Proline) — support softer, more resilient-looking lashes.
-
Ergothioneine & Oleanolic Acid — antioxidant support for the lash line.
The science: independently tested for safety
MD Lash Factor® Ultima uses a physician-developed, prostaglandin-free formula backed by independent safety testing.
-
Ophthalmologist-tested, 4-week in-use ocular safety study. In an IRB-approved in-use evaluation conducted at Clinical Research Laboratories (Study CRL32009) under the supervision of a board-certified ophthalmologist, 33 women — including contact lens wearers, non-wearers, and people with self-assessed sensitive eyes — used the formula daily for four weeks. The formula “did not demonstrate a potential for eliciting ophthalmic irritation” and was determined clinically safe for all three groups.
-
Examined by an ophthalmologist. No corneal abnormalities or superficial punctate keratopathy were observed on slit-lamp examination, and there were no clinically significant changes in visual acuity or tear-film break-up time.
-
Suitable for contact lens wearers. In that study, no changes in contact lens colour, scratches, or deposits were observed after four weeks of use.
-
52-subject repeat-insult patch test (RIPT). In an independent RIPT conducted by AMA Laboratories, Inc., the formula was evaluated in 52 subjects for dermal irritation and sensitisation potential.
-
Independent EU cosmetic safety assessment. A qualified safety assessor reviewed the full formulation under EU Cosmetics Regulation (EC) No 1223/2009 and concluded that every ingredient carries an adequate margin of safety and that the product is safe for use as directed.

How to use
Once daily, apply a single stroke of Ultima along the upper lash line, as you would eyeliner — more is not better. Allow to dry before applying other eye products. Use once nightly as directed.
Formulated without
No prostaglandin analogues (no bimatoprost, travoprost, latanoprost, unoprostone, or dechloro ethylcloprostenolamide). No prescription drug of any kind. Fragrance-free and paraben-free.
Frequently asked questions
How is Ultima different from the Original MD Lash Factor®?
Both are physician-formulated by Dr. Susan Lin and priced the same. The Original delivers our clinically measured lash-length results. Ultima is the prostaglandin-free alternative for sensitive eyes and contact lens wearers. It has been tested for ocular safety; it has not been tested for lash length.
Does Ultima contain any prostaglandin or prescription drug?
No. Ultima contains no prostaglandin analogue and no prescription drug of any kind.
Is it safe if I wear contact lenses?
In the 4-week ophthalmologist-supervised in-use study, contact lens wearers showed no changes in lens colour, scratches, or deposits, and the formula did not demonstrate a potential for eliciting ophthalmic irritation. If you have an eye condition, check with your eye-care professional before use.
I had irritation with another lash serum — can I use Ultima?
Ultima is the prostaglandin-free option created for exactly this situation. Introduce it gradually and discontinue use if irritation occurs.
