Moist layer cushion

A naturally-occurring nucleoside that signals skin to behave more like its younger self: smoother surface, calmer tone, firmer feel. Approved as an active in many regions, it pairs beautifully with peptides and antioxidants and is gentle enough for most reactive skin. A quiet workhorse of K-beauty firming serums.

Spherical carbon molecules — yes, the same family awarded a Nobel Prize in chemistry. In skincare they act as exceptionally efficient antioxidants, neutralising free radicals at a scale conventional vitamins struggle to match. A signature of luxury Japanese skincare; in Korean ampoules they signal performance and prestige.

The deep amber oil pressed from sea buckthorn berries — distinct from the fruit extract in its lipid profile. Rich in palmitoleic acid (rare in plant oils), it nourishes mature and dehydrated skin with a sensorial warmth. Use sparingly: a single drop is enough to lift a finishing balm or facial oil.

The lowest-molecular-weight form of hyaluronic acid, small enough to slip past the surface and hydrate where the skin feels tight from the inside. A key partner to standard sodium hyaluronate — together they deliver layered, lasting hydration rather than a single surface drink.

A multitasking form of vitamin B3 that steadies almost everything on the skin’s wishlist: it tightens the look of pores, evens tone over time, calms redness, and supports the lipid barrier. Tolerated even by reactive skin and pairs gracefully with most actives — including retinol and exfoliating acids.
