What is it? An anti-inflammatory version of the signature Cowshed facial, it uses MariPharm’s CBD-infused cream. The aim is to help calm irritated, inflamed skin and address conditions like hormonal acne, rosacea, psoriasis and eczema.

Our verdict: “I have little patches of eczema on my face and because I cycle a lot I get quite dry skin. So the treatment started with a really deep cleanse before the facalist had a thorough look at my skin and told me where some of the problem areas were. Next, she did a steam and extraction. Then the mask was put on, which was infused with CBD, before finishing with a facial massage and moisturiser. My skin felt lovely afterwards – calmer and softer – and although I don’t think it got rid of my eczema, I noticed my foundation has been much easier to apply. And it’s worth mentioning: that night, I slept so deeply.”
