Reveal a brighter, more even complexion with this beginner-friendly vitamin C serum formulated to target dullness, dark spots and early signs of ageing.

  • What it is & what it does: A lightweight daily serum formulated with 13% pure Vitamin C (Ascorbic Acid) to brighten dull skin, improve uneven skin tone and help reduce the appearance of pigmentation and post-acne marks.

  • 13% Pure Vitamin C, Vitamin E & Super Vitamin E: Formulated with 13% Ascorbic Acid, Tocopherol (Vitamin E) and Tocotrienol (Super Vitamin E) to provide antioxidant protection while helping improve skin radiance and support collagen production.

  • Panthenol, Allantoin & Sodium Hyaluronate: Contains Panthenol to help support the skin barrier, Allantoin to soothe the skin and Sodium Hyaluronate to deliver lightweight hydration for comfortable daily use.

  • Gentle daily Vitamin C care: Developed as a milder alternative to higher-strength vitamin C serums, making it suitable for daily use and for those new to pure vitamin C.

  • Lightweight, fast-absorbing texture: The water-based formula absorbs quickly without leaving a sticky finish, making it easy to layer into your morning or evening skincare routine.

  • Helps improve multiple skin concerns: Regular use helps minimise the appearance of dark spots, acne marks, uneven skin tone and fine lines while restoring a healthy-looking glow.

how to use

After cleansing and toner if using, shake the bottle lightly once or twice from side to side.
Apply a few drops to the skin.
Use fingertips to gently massage and absorb the serum, starting from the inside of the face working towards the edges.
