The INKEY List, like The Ordinary, sells single well-labelled actives at low prices and explains them plainly – behaviour we're happy to reward. For core actives (niacinamide, hyaluronic acid, salicylic acid) it's a straightforward, honest option.
Some of its trendier "peptide" and specialty launches ride hype more than data, so grade those individually. Strong value, best on its simple actives.
