A light serum formulated with 10% niacinamide and azelaic acid to even out skin tone and reduce pigmentation, redness, and facial photoageing. Niacinamide has been shown to reduce the appearance of acne lesions. Salicylic acid gently exfoliates while sodium lactate and sodium hyaluronate protect skin's moisture balance. Azelaic acid is derived from wheat, rye and barley. Its anti-inflammatory and anti-bacterial properties combat clogged pores and acne. Studies show that azelaic acid can reduce hyperpigmentation. If you prefer a more concentrated azelaic acid serum, try Lumizela 15% Azelaic Acid Serum Free of parabens, silicones, PEGs, SLS, SLES, and mineral oils. Vegan and cruelty-free. Made in the UK. Use on its own or underneath your favourite moisturiser. Facetheory products contain a high concentration of actives, so only a small amount is required per use.
