This Is Silk contains a proprietary silk peptide, which, during clinical testing, was found to outperform leading peptides in the production of keratinocytes and fibroblast cells, leading to more collagen production – the key to firm, bouncy skin.
Modern dermatology is more sceptical, but peer-reviewed studies indicate that silk can significantly aid skin healing, and the application of silk in diabetes treatment and in corneal, nerve (Parkinson’s) and tissue repair are all currently being investigated.
Those with highly sensitive skin have long since found comfort in soft, cooling silk, while those of us with fine, frizzy and/or fragile hair may find fewer tangles, snags and hairballs after switching to it.
Following an extreme allergic reaction at Christmas, I used Keay’s Power Up Silk Concentrate (£78) after my dermatologist-prescribed steroids course had ended, and I believe it made a positive difference to my skin’s recovery.
Slip’s silk pillowcases, sleeping masks and hair ties (all of which I use regularly) are pricier than those found on Etsy and elsewhere, but founder Fi Stewart has the data to prove their superior performance.
