I agree, she uses a lot of products, procedures, and devices I would stay clear from... For my part, I'm so happy that I went down the laser route. And I switched completely to Drunk Elephant. It's not to say that DE is the best, but sticking with one routine and the right ingredients will make such a difference. I'm not surprised to see influencers with badly messed up skin by testing out gazillion of products.
Back to WA: Somehow the shade descriptions changed. I'm pretty sure that Atelier 0 was once called "rose" and it says yellow undertone. I also don't think that Atelier I has a neutral undertone. In fact, I find it pretty yellow. When I use the stick foundation, I go for two shades at least, most likely N and 0,5. It looks very natural on me. That's what I really appreciate about WA.
