This makeup product instantly becomes a staple in your kit after a single use. It gives the look of perfectly effortless, well-groomed brows in under 20 seconds. Why is this product one of Glossier’s best sellers? It hits every one of Don Norman’s principles. Viscerally, the product itself is minimalistic and sleek. Behaviorally, it’s one of those “oddly satisfying” things to see your eyebrows go from unkempt, to suddenly controlled. This transformation is really satisfying. This experience is also reflective because when you look in the mirror, your self-image is enhanced.
