A best-seller from the brand best known for their viral shimmer sprays, the ICONIC London Underglow Blurring Primer has become a staple thanks to its hydrating, blurring finish

Until March 29, LOOKFANTASTIC shoppers can snap up this fan-favourite primer with a whopping 20 per cent discount, bringing the price down to under £20 – a total steal on best-selling beauty.

A best-seller from the brand best known for their viral shimmer sprays and liquid highlighters, the ICONIC London Underglow Blurring Primer is earning cult status  thanks to its hydrating, illuminating and blurring finish.

‘This is one of the very few items that I could not be without,' wrote one impressed five-star reviewer. ‘I’ve been using this forever!

‘The texture is like silk, the application is incredibly smooth, and it’s such a wonderful primer to use under your make-up. I use this under the iconic radiance glow and they work together like a dream!’

Fusing the benefits of skincare with high-performance makeup, the lightweight liquid primer has been formulated to deliver a glowing, soft-focus veil that leaves skin looking smooth and perfected.

Smoothing into my skin like a dream, the Underglow primer instantly added a radiant sheen to my skin, leave my skin glowing without chunks of glitter

Semi-satin in finish, it melts into the skin to create a smooth and radiant base for makeup, leaving a filter-like finish on the complexion that helps makeup last longer and look better.

This is all thanks to the vitamin C and champagne pearl-infused formula that works together to leave skin blurred and illuminated, with the vitamin C helping to protect the skin from free-radical damage and premature skin ageing.

The primer also includes Artemisia Capillaris – a clever Japanese plant extract that helps to protect the skin against Blue HEV Light (from your smartphones and devices), working overtime to help reduce the effect of accelerated ageing caused by blue light exposure.

The brand recommends applying 2-3 drops of the primer all over the face, focusing on any areas that are often prone to excess shine. However, I opted to apply all over my face and totally loved the results.

Even with just my lightweight base product and no setting spray, my skin was incredibly blurred and smooth thanks to the primer

Smoothing into my skin like a dream, the Underglow primer instantly added a radiant sheen to my skin, leaving my skin glowing without chunks of glitter – my idea of the perfect finish for makeup application.

I love how hydrating and quenching it felt, too, leaving my skin looking and feeling moisturised without greasiness, blurring my skin without leaving it flat and dull. The glow? Simply unreal.

As you can see from my photos, my skin looked healthy and radiant, and my makeup sat so beautifully on top of the primer that it almost looked like I was wearing nothing at all.

Smooth and quenched, my skin honestly looked like it had a soft-focus veil, and even helped my makeup look perfect all day long, which for me is a total must.

This primer is definitely now a staple in my makeup bag, and I can’t wait to try it worn alone or with minimal makeup for that no-makeup glow.

And hundreds of impressed users agree, calling it their ‘holy grail’ product and coining it their essential ‘repeat purchase’.

‘This primer is so hydrating and blurring and leaves your skin feeling really smooth before applying makeup and never pills!’ Wrote one impressed reviewer.

Another added: ‘It’s a genuine game changer. Provides a healthy base and glow to the face - I was sceptical but have been completely won over.

‘I am a mature customer and have used many products over the years - I can confirm that this is up there with the very best I’ve used.’
