How to Patch Test Lash Serum Before Starting a New Routine

Patch testing is a smart step before using any new eye-area product, especially if your eyes or skin are sensitive.

Start Small

Apply a small amount to a less sensitive area of skin and watch for discomfort before using near the eyes.

Watch for Reactions

If redness, burning, itching, swelling, or discomfort occurs, do not continue using the product.

Apply Carefully

When ready, apply 2Bmagic Lash & Brow Enhancing Serum as a thin line along the upper lash line. Avoid the waterline.

Final Takeaway

Patch testing helps make your lash routine more careful and confidence-building.
