Maybe? Not really? Sort of? Well, I use both, sometimes together and sometimes separately, and, sure, they are kind of same-ish, but also really different. They both give the skin that angelic glow and bring out the best of our bone structure. But more so than anything, they make the skin photograph well, often making it appear years younger. Why? It’s all about finding that perfect light (insert some Tyra ANTM quote here). The big difference is in the application.
Powders will do, like Stila’s multipurpose All Over Shimmer; just be aware of the J.Lo effect (you don’t want to look sweaty all the time). The ones that come with a fine brush, like the cult favourite from Benefit, are the most precise: dab a little, blend a little, and it’s a world of difference. Of course, the legendary YSL’s Touche Éclat is the one that started it all, twenty years ago — next one on my highlighting list.
