A marshmallow-scented makeup primer from the chemist is being called the ‘holy grail’ product

A makeup primer has gone viral online after customers noticed how much smoother their foundation and cream products applied on top of it.

The NYX Marshmallow Smoothing Primer, which is $29.95 at Priceline and comes in a light pink tube, is revered for its ability to create shine and tone down oiliness all day.

A horde of committed fans have taken to TikTok to showcase exactly how it works, claiming it has as many as 10 benefits like softening fine lines, hydrating the skin and evening out skin tone.

While a number of would-be skeptics said they didn’t have high hopes for the fairly cheap finishing product, they were left pleasantly surprised when they tried it. 

‘There’s one thing I don’t like about this primer (the sweet, but not overpowering, scent) and about five things I do,’ one woman said.

‘I like the fluffy and whipped texture (fun!), the soft-focus and blurring it performs on skin, and that it sits obediently and transparently over sunscreen.

Infused with marshmallow root extract, the primer dries down to be completely transparent on the face with skincare-quality ingredients

‘I wear it as the last layer before I leave the house, no foundation over the top, and it’s like I have a real-life filter on my face.’

Another makeup buff was pleased she ordered the primer before it got ‘too popular’ and harder to find available online. 

‘My skin is temperamental, no severe issues but a little bit of everything,’ she said in her review.

‘Combination, big pores, fine lines, texture. I’ve been using this on top of my regular skincare (toner, moisturiser, SPF) and under light makeup (BB cream, powder, brows) and I love the effect.’
