A vitamin C concentrate that layers under your Geneskin routine
Isispharma Geneskin C Premium Radiance Concentrate is a radiance concentrate built around a stable form of vitamin C, designed to brighten a dull, tired-looking complexion and support the rest of the Geneskin anti-aging range. A few drops each morning gives skin a fresher, more even-toned base before the day cream.
The texture
A fluid, fast-absorbing concentrate that leaves no stickiness, so it layers easily under a moisturiser or sunscreen without pilling.
Who it suits
- Dull, tired-looking skin that has lost its glow
- Anyone already using the Geneskin day or night care
- Uneven skin tone from sun exposure or fatigue
- Those who want a light vitamin C step, not a heavy serum
Worth knowing before you buy: vitamin C can make skin more sun-reactive; always follow with sunscreen in the morning.
