FAQs
Q1. How does Bimatoprost 0.03% in Trulush Eyelash Serum make lashes grow longer and fuller?
A1. Bimatoprost is a prostaglandin F2α analog that binds to prostanoid receptors in eyelash follicles, extending the anagen (active growth) phase of the eyelash hair cycle while increasing the number of follicles simultaneously in growth. The result is lashes that grow for longer before resting, appear in greater density, and develop darker pigmentation through increased melanin deposition in the follicle. Trulush Eyelash Serum delivers Bimatoprost at 0.03% — the same concentration in the FDA-approved eyelash treatment indication.
Q2. Is it safe to use Trulush Eyelash Serum if I wear contact lenses?
A2. Yes, with a simple precaution: remove contact lenses before applying Trulush and wait at least 15 minutes before reinserting them. This prevents preservatives in the formulation from absorbing into soft contact lenses. The serum should only be applied to the upper eyelid margin (base of upper lashes) using the provided applicator — it should not drip directly into the eye.
Q3. Can I apply Trulush to my lower lashes or eyebrows for similar results?
A3. No — apply Trulush Eyelash Serum only to the upper eyelid lash line. Applying to the lower lash line increases the chance of the solution draining into the eye. Unintentional contact with skin around the eye can cause localised periorbital darkening (hyperpigmentation) or unwanted hair growth on surrounding skin. Blot any excess with a tissue immediately after applying, before it can spread beyond the lash margin.
Q4. How long before I see visible eyelash growth results with Trulush?
A4. Most users notice longer, fuller lashes within six to eight weeks of daily evening use. Full results — including maximum length, density, and pigmentation — typically develop by twelve to sixteen weeks. The eyelash growth cycle spans approximately four to five months, so consistent daily application is necessary throughout this period. If treatment is discontinued, lashes gradually return to their original appearance within a few weeks to months.
Q5. Can Trulush Eyelash Serum change my eye colour or iris pigmentation?
A5. When Bimatoprost is instilled directly into the eye (as glaucoma drops), increased iris pigmentation has been reported in patients with light-coloured irides. When used as an eyelash serum applied externally to the lash line — not dropped into the eye — the risk of iris colour change is very low with correct application. Patients with hazel, blue, or green eyes should apply carefully with the provided applicator and blot excess product; those with pre-existing eye conditions should consult an ophthalmologist before starting Trulush.
