What the gurus are saying

The shade range falls short, with swatches that don't match the skin tones they're meant to represent. The formula also struggles with trendy mixing techniques, it gummed up when frothed with water instead of blending smoothly, a real limitation if that's how people want to use it.

"I understand brands have a budget, but a few changes here could have been a lot better. There's like five or six shades along the way, 7, 8, 10 even, where you can change them. There's just something really off. A lot of people pointed out also that none of the tones on these swatches even match with the arm in the swatch, which is a really, really good point. There's just something not quite right."

"When I tried to mix this foundation with water in the frother, it gummed up on the frother and didn't even mix. The foundation and water separated because oil and water don't mix together, so this didn't work at all with the frothing trend."

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.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

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.
