Kiehl’s Facial Fuel Energizing Tonic For Men contains Caffeine, Vitamin C, Vitamin E, and Bamboo Extract to provide relief and restore balance to the skin. Part of the Facial Fuel collection, this toner was meant to energize and invigorate the skin after shaving. Overall, as effective as this toner may be, especially in tandem with the rest of the collection, we think this product may be too strong for those with sensitive skin and noses.
