Who it's for
Best for women and men wanting a high-potency vitamin C serum to address brightening and anti-ageing concerns. Suitable for all skin types — particularly skin showing dullness, uneven tone, dark spots or early signs of ageing. Always pair with a daily broad-spectrum SPF when using vitamin C, as it can make the skin more sensitive to UV exposure.

- Dispense 1–2 pumps onto clean fingertips.
- Press gently onto the face, neck and the back of the hands.
- Allow to absorb fully before applying moisturiser or SPF.
