For mild skin brightening we recommend using Nrj-Net Revitalising Cleansing Mask. Apply twice a day, morning and night, spread evenly and leave on for 1-2 minutes. Rinse with tepid water. Your skin may go bright red, which is a normal and desirable reaction and will subside in 10-20 minutes. Nrj-Net contains a large dose of niacinamide or vitamin B3, which stimulates the capillaries and gently brightens the skin without increasing its sensitivity to UV.
