To use this Espoir brow color fixing product, first, make sure your eyebrows are clean and dry. Take the cone - shaped skinny brush and gently apply the product from the inner corner of your eyebrow towards the outer edge, following the natural shape of your brows. You can add more layers for a darker look. When using, don't apply too much at once to avoid lumps. After use, keep the product in a cool, dry place. If you notice any skin irritation, stop using it immediately.
