What the gurus are saying

The ultra-fine micro tip earns praise for letting people sketch hairlike strokes without heavy, dark lines right away, giving a natural build that's forgiving for those less confident with brow makeup. The wax formula strikes a balance between pigment and control, delivering colour gradually so you have room to adjust, and the pencil lasts remarkably long. One expert notes it's the tiniest eyebrow pencil she's tried, even next to established favourites, making the precision particularly approachable for detailed work.

"This comes in six shades and I feel like it just delivers the perfect amount of pigment with each stroke. It also lasts for a really long time. In order to make it last even longer, I use this mainly for my inner brows where you need more definition and to draw more hairlike strokes, and then I use something that's cheaper and maybe a little bit thicker to do the middle and also the tail of the brow. But this is so good and I'm so grateful that this was invented."

"The Kosas Brow Pop Nano, I go through way too many of these. I have asked several times that they sell this in a three pack because I go through a ton of it. I'm medium brown, and that has like become the shade that I go to the most. I will buy two or three of those because I have to keep more than one in my makeup bag. The worst is when you don't realize that you were about to finish up that brow pencil and it happens really quickly."

"It has this really [...] tiny nano tiny pencil tip that glides on so beautifully. I use so many of these, I actually buy it like in threes. I've been begging the brand to make packs of threes because that would be very helpful. My only critique is that it's so skinny that you go through so much of it. I go through like one of these every three weeks or so, and I want to always have one in my bag as a backup because you don't know when you're really going to run out of it."

"I wonder if I can show you on camera how tiny this is. The tiniest tiniest pencil. Look how itty bitty. It's a really nice pencil too."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Sunscreen filters

Sun protection is the best evidenced way to slow visible ageing, and the filters are what does the work. Mineral and chemical filters both protect when a product is applied thickly enough and often enough, which is where most people fall short rather than on the choice of filter.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
