Purify your skin with the Kiehl's Blue Astringent Herbal Lotion. Perfect for people prone to oily skin, as the lotion is infused with potent camphor, offering a refreshing, cooling effect. This is emphasised by tantalising menthol, allowing the toner to lessen the appearance of excess shine and sebum. The astringent lotion is finished with sodium PCA, a powerful humectant that helps to drench your base in moisture, avoiding any uncomfortable tightness.
