Get answers to common questions about Patch Test.

A Patch Test applies a small amount of lash or brow product to your skin to check for allergic or irritant responses. It prevents adverse reactions and ensures we select safe products before performing full lash or brow services.

We recommend booking your Patch Test at least 24 to 48 hours before your scheduled lash or brow appointment. This timeframe allows us to detect delayed reactions and confirm product compatibility so your full treatment can proceed safely.

No — the Patch Test is non-invasive and typically painless. We apply a tiny amount of product to a discreet skin area and observe for redness or swelling. Any discomfort is minimal, and we won’t proceed if there’s a reaction.

If the Patch Test shows a reaction, we stop use of that product and discuss alternatives, hypoallergenic options, or a specialist referral if needed. Your technician will recommend the safest next steps to protect your skin and eyes.

Most reactions appear within 24 to 48 hours, which is why we ask clients to monitor the test site during that period. Immediate sensitivity can occur sooner, and we’ll advise whether it’s safe to proceed.

Yes — we strongly recommend a Patch Test for first-time lash and brow clients. It’s a quick precaution that identifies sensitivities, helps choose safe products, and reduces the risk of irritation during your full service.
