But there is one major exception: Kate Bosworth. Yes, not only is she the star of everyone's favourite early noughties surf film, Blue Crush, and friend to another of my beauty icons Rosie Huntington-Whiteley, but Bosworth's Instagram is also a treasure trove of truly amazing makeup advice—with her IGTVs covering everything from Italian-inspired beauty looks to what to do when you've forgotten your makeup bag.
"One of the things that I”m really passionate about is the integrity of skin," Kate revealed in her "Italian Romance"–inspired" makeup tutorial for IGTV. "I'm a real excavator of the perfect foundation, and one of the foundations that I really love to use—especially in my day to day—is this one from Koh Gen Do (£72). It's a moisture foundation, and for me, the foundations that work the best are the ones that do have moisture and have some hydrating elements to them. If the foundation is too dry, then I just feel like you see all the cracks and the creases in my skin and it's just not the look I'm going for."
"For everyday looks, concealers can go a long way—especially if you spread them around to create a foundation-like consistency," she explained. "I'm going to use some moisturiser to expand the concealers that I have. We're going to add some moisturiser to make these products stretch a little bit further than they normally would."
Rather than fussing with multiple makeup brushes and sponges, Kate is a real advocate for using her fingers to apply her products. "I use my fingers quite a bit to apply makeup," Bosworth revealed in a makeup tutorial with Rosie Huntington-Whiteley. "There's something about the skin-on-skin… and even brushes sometimes can intimidate me slightly."
For best results, stick to cream and liquid products like Kate's favourite Glossier Lidstar Eye Shadow (£15), as powders tend to work best when applied with a brush.
Turns out, you don't need a whole stash of brow pencils, spoolies and pomade to create fuller-looking brows. When Kate found herself without her favourite brow pen, she used a trick that she learned backstage.
"So one trick that a makeup artist told me quite a while ago which I use when I'm in a pinch is to take a little bit of balm and bring a little bit of it to my lashes and my eyebrows to thicken," Kate explained.
"I’m going to use this toothbrush to apply the balm to my brows. I’m just going to brush it into the toothbrush and then apply it to the brow. It actually looks really good and pretty full."
Like me, Kate Bosworth isn't a huge fan of lip liner, telling Rosie HW that she likes it on other people but not on herself. "I don't love my mouth with a lip pencil, I normally use the edge of the lipstick for a little distinction," she explains.
Instead, she layers lipsticks to create a fuller-looking pout with a subtle ombré effect. "I sometimes put the lipstick that's a little bit brighter on the top of where the base is. It just lifts it, I think," Bosworth revealed.
