Nature Derma Niacinamide Toner Essence is a soothing toner that helps unclog pores, balance excess sebum while sealing-in moisture and supports soothing of acne breakouts. The effective blend of Niacinamide, Grapefruit Extract, and our Natural Biome-BoostTM Solution helps to keep the skin firm and healthy. This toner is known to keep sebum production in check and help reduce the appearance of pores. Grapefruit extract is known to be rich in vitamins C and E, which help maintain collagen levels. Our unique Natural Biome-BoostTM Solution is known to strengthen the skin barrier to protect it against environmental stressors like pathogens, toxins, pollution, and sun damage. This delicate yet critical barrier is further strengthened each time you use the toner, thus giving you balanced, healthier skin.
