The INKEY List Serum – Niacinamide, Hyaluronic Acid, Collagen Peptide - Certified from TheINKEYList

The INKEY List serums are concentrated skincare treatments designed to deliver powerful, targeted ingredients directly to your skin where they can actually do something useful. Formulated with high-performance actives like hyaluronic acid, niacinamide, peptides and more, these serums are lightweight, easy to layer and suitable for a variety of concerns such as hydration, oil control, texture irregularities and early signs of ageing. The idea is simple: skip the marketing fluff, focus on what works, and let your routine be customised around products that are honest about what they’re doing and why.

The INKEY List Niacinamide Serum

This serum uses 10% niacinamide (a form of Vitamin B3) to help balance your skin and calm visible oiliness, redness and uneven tone. It’s basically the cheat code for congested or combination skin: niacinamide helps regulate excess sebum and can reduce the appearance of pores and blemishes, while also soothing irritations that make your skin look dull or uneven. Because it’s lightweight and gentle enough for morning and evening use, it fits into most skincare routines right after cleansing and hydrating, and before moisturiser.

The INKEY List Collagen Peptide Serum

This is a peptide-powered serum that doesn’t actually contain collagen, but nudges your skin to behave like it’s producing more of its own collagen. It uses Matrixyl 3000 and Syn-Tacks dual peptides to help support skin elasticity and reduce the look of fine lines and wrinkles, basically a science-forward way to try to preserve that plump, springy look your skin likes to lose as time goes on. Lightweight and hydrating, it layers nicely with other products and fits into both AM and PM routines after cleansing and hydrating steps.

The INKEY List Hyaluronic Acid Serum

This is the hydration serum that actually does what it promises: delivers moisture deep into your skin without feeling sticky or greasy. With multi-molecular weight hyaluronic acid, it attracts and holds water across different layers of the skin, leaving it looking plumper, smoother and less flaky. It’s one of those “no fuss” essentials that works well on its own or under other treatments, and it plays nicely with pretty much everything you already use.
