Susanne Kaufmann Blue Light Defence Mist is a highly effective face mist developed to help protect the skin against daily oxidative stress caused by infrared radiation and blue light from our phones and screens. A blend of anti-ageing Ectoin and Q10 help protect against damage, keeping skin hydrated and promoting collagen production, while silk extract regenerates and soothes the skin. In addition, butterfly bush flower extract helps reduce redness and pigmentation caused by blue light.
