Jack Black Brightening Booster Vitamin C Serum (30ml)

Brighter, more even skin starts with the right Vitamin C. Jack Black's Brightening Booster Vitamin C Serum is a hydrating, multitasking formula packed with antioxidants and built around 10% THD Ascorbate - a highly stable, oil-soluble form of Vitamin C shown to improve skin brightness and pigmentation with continued use.

Unlike standard Vitamin C formulas that can degrade quickly or cause sensitivity, THD Ascorbate is exceptionally stable and well-tolerated, making it an effective choice for a wide range of skin types. Black Myrobalan brings additional brightening and antioxidant power rooted in centuries of Ayurvedic tradition, while sustainably farmed Green Microalgae helps defend skin against the damaging effects of blue light. The result is a serum that genuinely moves the needle on skin tone, radiance, and long-term protection. 

Available in 30ml.
