This brow shaper is the only one that looks natural. I've been using it for probably twenty years -- nice to have so many color choices. The brushes really last a long time!
I have tried many brow shapers including Bobbi Brown and Giorgio Armani. Clinique is by far the best. It is a powder that is applied with the accompanying brush. My eyebrows are a mix of dark brown, black and gray. Every brown I had tried was too red or too dark for me. There are not many gray products available - no one wants gray eyebrows. However, Clinique blends with my natural colors and does not look gray. Clinique charcoal is perfection. The product is easy to apply, fills bare spots, is long-lasting and looks very natural. It is also easy to correct your mistakes. I love Clinique Brow Shaper and recommend it highly.
