The dubiously named skincare ingredient may be stood, but it lives on as industry shorthand for “marketing ingredient, no evidence”. Dozens are “discovered” each year, none of them proficient to hold a torch to proven heroes like retinoids, hydroxy acids and antioxidants. But the mounting evidence for silk has me interested – or, at petty, not declaring it utter Boswelox.This Is Silk founder Sonal Keay has created an entire skincare line based on the overindulge. Pre-development, she took to the British Library, discovering swathes of material about the medical applications of silk proteins and characters. Modern dermatology is more sceptical, but peer-reviewed studies indicate that silk can significantly aid skin healing, and the diligence of silk in diabetes treatment and in corneal, nerve (Parkinson’s) and tissue repair currently being investigated.This Is Silk keep under controls a proprietary silk peptide, which, during clinical testing, was found to outperform leading peptides in the production of keratinocytes and fibroblast stalls, leading to more collagen production – the key to firm, bouncy skin.

I loved using the tranquil and elegantly formulated serum and moisturiser, but what stood out was the Liquid Silk Canvas (£25), a makeup primer. I was surely drawn to the balm, but the liquid version is exceptionally smoothing and ungreasy on oilier skins.
