Lumigan 0.03% Eyelash Serum 3ml

What is Lumigan (bimatoprost 0.03%)?

Lumigan is a prescription solution containing bimatoprost 0.03%, a synthetic prostaglandin analogue. Originally licensed for glaucoma, it was found to produce a consistent and striking side effect: longer, thicker and darker eyelashes. That effect is now its most common off-label use in the UK.

The US brand Latisse contains the same active ingredient at the same concentration. Lumigan is the original prescription brand available in the UK; both are clinically identical.

How bimatoprost grows lashes

Eyelashes cycle through three phases: growth (anagen), transition (catagen) and rest (telogen). Most lashes spend only a short time in anagen, which is why they stay short. Bimatoprost works by binding to prostaglandin receptors in the hair follicle, which:

• Extends the anagen (active growth) phase, so each lash grows for longer before it sheds
• Increases the proportion of follicles actively growing at any one time
• Stimulates melanin production in the follicle, darkening the lash shaft

The effect is cumulative. Lashes resting at the start of treatment enter the growth phase as the cycle progresses, so results build steadily over 12-16 weeks.

Lumigan vs Latisse

Both contain bimatoprost 0.03% and are made by Allergan. The only difference is commercial: Lumigan is the ophthalmic (glaucoma) brand; Latisse was later created specifically for the US cosmetic lash market. In clinical practice they produce identical results. In the UK, Lumigan is the standard prescription formulation for lash growth and is typically more cost-effective.

Results timeline

• 4-8 weeks: visible lengthening and thickening begins
• 12-16 weeks: full results, lashes at maximum length and density
• Ongoing use: results maintained with continued nightly application
• On stopping: lashes gradually return to pre-treatment state over several weeks

Clinical trials report up to 25% increase in lash length, 106% increase in thickness, and a significant increase in lash darkness.

How to apply

Apply once daily in the evening to clean, dry skin:

• Remove contact lenses; wait 15 minutes before reinserting after application
• Place a single drop onto a clean applicator or fine brush
• Draw along the base of the upper lash line only, as you would a thin line of eyeliner
• Blot any excess immediately below the lash line
• Do not apply to lower lashes directly (they receive treatment by contact transfer)
• Do not place drops directly in the eye

Side effects

Bimatoprost is well-tolerated when applied correctly to the upper lash line rather than into the eye.

Common (roughly 1 in 10)

• Skin darkening (hyperpigmentation) at the application site. Usually reverses when treatment stops
• Mild eye redness or irritation, particularly if solution reaches the eye directly

Uncommon (roughly 1 in 100)

• Itching or dryness of the eyelid margin
• Darkening of the eyelid skin

Rare (less than 1 in 1,000)

• Permanent iris pigmentation (darkening of the coloured part of the eye), mainly reported in glaucoma patients using bimatoprost as a direct eye drop over many years. The risk with correct upper lash-line application is very low

When to seek urgent medical advice

• Signs of allergic reaction: facial or lip swelling, difficulty breathing, rash
• Significant eye pain, blurred vision or new sensitivity to light

Not suitable during pregnancy or breastfeeding, or if you have active eye inflammation.
