This universal eyebrow pen features an exclusive oval tip that mimics the look of real hair, adapting to your eyebrow color based on the pressure. Available in four universal shades to suit each hair color and cover gray hair. A scratch-resistant and skin-sticking combination for long-lasting natural-looking eyebrows, while the built-in Poly brush works for a perfect sleek look. Eyebrow Enhancement Ingredients: Combine the power of the eyebrow between biotin and sawmill for stronger, healthier hair and skin, as well as antioxidants to help reduce the appearance of signs of skin damage and aging. Beauty Tip: The beginning of your eyebrow should align directly with the edge of your nose. It should mimic the arch of your eyebrow with the outer edge of the rainbow, and the end of your eyebrow should align with the outer corner of your eyes. How to apply, the deeper you press your eyebrow color, if your eyebrow is on the lighter side of the shadow family, use gentle strokes. If your hair color is darker, use tougher strokes. Finally, comb your light eyebrows using the built-in Poly.
