This single-ingredient serum is made with 100% THD Ascorbate, a potent-yet-gentle Vitamin C derivative crafted in Japan. Refined through a multi-step process for unparalleled stability and potency, this springy gel-oil texture absorbs 3x more efficiently than traditional vitamin C for results you can see. This antioxidant-rich powerhouse works to diminish hyperpigmentation and supports skin’s natural collagen. Skin feels instantly hydrated, supple, looks brighter and visibly more even in just 2 weeks. Original size and refill: 20ml
