The INKEY List

The INKEY List is a UK skincare brand, launched in 2018, built around single active ingredients marketed with what it calls “clear guidance, proven ingredients, real results.” Its range spans cleansers, serums, moisturizers, and treatments organized by skin concern and active ingredient, sold at accessible price points through Boots, Sephora, Amazon, and its own website. The brand is B Corp-certified and markets its formulas as fragrance-free, cruelty-free, and vegan; its Fulvic Acid Brightening Cleanser, using Nordic peat-derived fulvic acid, helped bring a peat-derived ingredient into mainstream retail.

The INKEY List is an UK brand built around fulvic acid.

Fulvic Acids — the smallest, most bioavailable fraction of humic substances — is used in treatments like peat bath additives, peat compresses, and peat cream / lotion, most often explored for dry skin (xerosis), muscle pain and tension, eczema (atopic dermatitis), and joint inflammation (osteoarthritis, rheumatic conditions).
