Reverse time with the Peter Thomas Roth Potent-C Power Serum; a rich, moisturising serum that unleashes the anti-ageing and brightening benefits of Vitamin C to help improve the look of wrinkles, uneven skin tone, firmness and texture. Powered by THD Ascorbate (an ultra-stable scientific breakthrough ingredient 50 times more powerful than traditional Vitamin C), the serum also contains a 20% concentration of Vitamin C, amplified by the addition of two potent antioxidants. Fragrance-free and non-irritating, the age-defying serum is the answer to a radiant, youthful-looking complexion.
