Product description

Macaroni Penguin is a prescription brow treatment. Bimatoprost extends the growth phase of the follicle, so brow hairs grow longer and fuller and more of them are growing at any one time. It's the same active and strength as our Giraffe Lash Booster, supplied for the brow line.

It's for adults aged 18 to 65 with thin, sparse or over-plucked eyebrows, with no eye condition that rules bimatoprost out. Because the brow sits close to the eye, the same eye precautions apply.

The active

  • Bimatoprost 0.03%. A prostaglandin analogue that extends the growth phase of the brow follicle and increases the number of hairs in growth at once.

Prostaglandin analogue

Who it's for

  • Adults aged 18 to 65
  • Sparse, thin or over-plucked eyebrows
  • No glaucoma treatment, eye infection, uveitis or recent eye surgery
  • Brow skin free of cuts, rash or infection

The consultation checks all of this. A prescriber makes the final call, and tells you why if the answer is no.

Stages of regrowth

What happens, and when.

Hair grows slowly, so this is the shape of a typical course rather than a promise. Everyone responds differently, and your prescriber sets the pace.

  1. Weeks 1–4

    The nightly routine

    A thin line through each brow every night, on clean skin. Nothing visible yet.

  2. Weeks 4–8

    First change

    Brow hairs start to look a little longer and the sparse patches a little less bare.

  3. Weeks 12–16

    Full effect

    Fuller, darker brows — the complete result. Your prescriber may suggest a lighter maintenance schedule from here.

  4. After 16 weeks

    Maintain

    Brows gradually return to how they were over a few months if you stop. A typical path, not a promise — individual results vary.

How the consultation works.

Free, around five minutes, no obligation.

Start consultation
  1. 1

    Answer a few questions

    About your hair, your health and any medicines you take. Around five minutes.

  2. 2

    Upload photo ID

    The prescriber confirms your age from it. If we need a photo of your scalp, beard, lashes or brows, we'll ask.

  3. 3

    A prescriber reviews it

    A UK-registered prescriber checks every prescription order before it is dispatched. If treatment isn't suitable, they'll say so and why.

  4. 4

    Delivered, then checked in on

    Free tracked UK delivery. From your second order onward, a short health check-in keeps your prescriber up to date.

How to use it.

  1. 1

    Follow the directions in the pack

    Your prescriber's directions and the leaflet come first.

  2. 2

    Clean, dry brows

    Remove make-up. One drop on a fresh applicator.

  3. 3

    Along the brow

    Draw through each brow in the direction of growth, on the skin where hair is sparse. Blot any excess and keep it away from the eye.

  4. 4

    Nightly, then patience

    Once a night. Change is usually visible from around eight weeks; full effect at twelve to sixteen.

Safety, in brief.

A summary, not the whole story. The leaflet in the pack and your prescriber's directions take precedence.

Common side effects

  • Itchy or red eyes
  • Darkening of the skin along the brow where it's applied, which usually fades after stopping
  • Dry or irritated eyes, or a feeling of something in the eye
  • Fine hair growth on skin that the product repeatedly touches

Do not use it

  • If you use eye drops for glaucoma or raised eye pressure, unless your eye specialist has agreed
  • If you have an active eye infection, uveitis or iritis, or have had eye surgery recently
  • If you are pregnant, planning pregnancy, or breastfeeding
  • If you are under 18 or over 65
  • If you are allergic to bimatoprost
  • If the skin of the brow is broken or inflamed

Precautions

  • Bimatoprost can permanently increase brown pigment in the iris if it gets into the eye repeatedly. This is more likely with mixed-colour eyes. Apply only to the skin along the brow and blot any excess.
  • Use a fresh sterile applicator for each eye, each night; never reuse one or share the product.
  • Remove contact lenses before applying and wait 15 minutes before putting them back.
  • If you already use bimatoprost eye drops, using both may reduce the drops' effect on eye pressure — tell your eye specialist.
  • Stop and contact us or an optician if you get eye pain, changes in vision, or persistent redness.
  • Hair gradually returns to its previous state over weeks to months after stopping.

Macaroni Penguin Brow Booster, answered

Your questions,
answered.

Straight answers, including about what this treatment can't do.

❏Five honest answers
Do I need a prescription?
Yes. Bimatoprost is a prescription-only medicine. A UK-registered prescriber reviews your consultation — including questions about your eyes — and your photo ID before Macaroni Penguin is dispatched.
Is this just Giraffe with a different name?
Same medicine, same strength, applied to the brow rather than the lash line. We list them separately so the consultation and directions match what you're treating.
Can it affect my eyes if it's only on my brows?
The risk is lower than with lash use, but bimatoprost near the eye can still cause redness, irritation, eyelid darkening and, if it repeatedly enters the eye, a permanent increase in iris pigment. Apply only to the brow, blot excess, and wash your hands after.
Will the hair grow where I don't want it?
Fine hair can grow on skin the product repeatedly touches, so apply precisely and wipe away anything outside the brow.
How long do results last?
Only while you keep using it. Brows gradually return to their previous state over weeks to months after stopping.
