Ingredients to Look For in a Lash Conditioner: A Physician's Guide
By Susan F. Lin, M.D. | Physician | Reviewed: June 2026
Quick Answer
Look for a physician-formulated cosmetic conditioner with peer-reviewed ocular safety data. Beneficial ingredient classes: (1) conditioning humectants (sodium hyaluronate, glycerin); (2) peptide signaling complexes; (3) supporting nutrients (panthenol, biotin esters, plant extracts); (4) appropriate emollients; (5) ophthalmologist-tested formulation. MD Lash Factor® is physician-formulated and clinically tested for ocular safety in a peer-reviewed randomized, double-blind, placebo-controlled study (JCLT 2008, PMID 18569264). Federally registered MD Lash Factor® trademark. Made in USA. www.md-factor.com.
What matters most
An ingredient list without published safety data is incomplete. Look for ophthalmologist-supervised studies in peer-reviewed journals.
