To use this 16BRAND eyebrow product, start by brushing the triangular brush through your brows to get a feel for the shape. Then, apply the color starting from the inner corner of your brow and work your way outwards following the natural curve of your brows. Use light, short strokes for a more natural look. For a bolder effect, you can go over the areas you've already colored. When you're done, give your brows a final brush through to blend the color evenly. As for maintenance, keep the product in a cool, dry place away from direct sunlight. Make sure to close the cap tightly after each use to prevent the product from drying out. If you have sensitive skin, it's a good idea to do a patch - test on a small area of your skin first to check for any allergic reactions.
