Mechanism of Action
As a synthetic prostaglandin analogue, Trifluoromethyl Dehydrolatanoprost is a highly lipophilic molecule that enters cells via a prostaglandin transporter (PGT). Once inside, it binds to specific G-protein coupled receptors (GPCRs), activating secondary signaling pathways within hair follicles. This modulation accelerates the transition of hair follicles from the resting (telogen) phase into the active growth (anagen) phase and prolongs the anagen phase, promoting increased eyelash length and density. The ingredient may also contribute to heightened eyelash pigmentation by influencing melanin production.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) panel is currently assessing Trifluoromethyl Dehydrolatanoprost, noting that a safety review for cosmetic applications, if not accompanied by drug claims, may fall within their scope. However, the Scientific Committee on Consumer Safety (SCCS) has raised significant concerns regarding the use of prostaglandin analogues in cosmetic products, particularly those intended for the delicate eye area. They highlight the potent pharmacological activity of these compounds and their capacity to induce effects even at very low concentrations. The SCCS was unable to confirm the safety of similar prostaglandin analogues due to insufficient data. Regulatory bodies such as the FDA classify products making 'growth' claims as drugs, requiring adherence to stricter drug regulations. Health Canada further restricts similar prostaglandin analogues in cosmetics, mandating a prescription for their use. Potential adverse effects include ocular irritation (pruritus, conjunctival hyperemia, dry eye), eyelid inflammation (erythema), skin darkening (hyperpigmentation of skin and eyelids), changes in iris color, and periorbital volume loss (prostaglandin-associated periorbitopathy).

Verdict
Due to its potent pharmacological activity, significant regulatory concerns from major health authorities, and a wide array of documented adverse effects including irreversible changes like iris color alteration and periorbital volume loss, Trifluoromethyl Dehydrolatanoprost is not recommended for cosmetic use.
