What the gurus are saying

One expert loved it for creating a fresh, glowy look without worrying about all-day wear, calling it beautiful for that dewy finish. However, another found it problematic: the formula was quite glittery, leaving sparkle on the skin and transferring onto clothes, which means anyone bothered by visible shimmer or product transfer may want to steer clear.

"This one is so great if you just want a little bit of like a dewy freshness added to the skin. I wouldn't say that this is necessarily like something that I reach for for longevity. It's more of like the finish of my skin, but it's really beautiful."

Trying NEW (Really Good) Makeup I Just Bought

"This Iconic London setting spray I think added a really healthy glow, but it did not like break down my makeup or cause it to look more oily, which I thought maybe it would. It's so pretty. I am so excited to like keep using this."

"I wasn't a fan of this. It was quite glittery. There was glitter on my hand. I spray up my hand and I tried to show you but you can't really see it but there was a lot of glitter and it was also on my clothes."

"One of my favorite setting sprays is the Iconic London Prep Set Glow and this is the one which has these gold so settle when you shake it up it's kind of gold and it leaves this amazing mist like this golden sheen on your face. It's really really good so I'm going to use it repurchase it."

What the evidence says.

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

Retinoids

Retinoids are among the best studied ingredients in dermatology, with solid evidence for acne and for the fine lines and rough texture that come from sun exposure. Dryness and flaking in the first few weeks are common and usually settle.

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.
