Unlike vitamin C products that have a color, the Dear, Klairs Freshly Juiced Vitamin Drop has a transparent formula and bottle.  This is due to the nature of vitamin C, which is vulnerable to light and heat. Rather than hiding the oxidation process of vitamin C, Dear, Klairs decided to show the process as it is so that customers can see the freshness with their own eyes. The Freshly Juiced Vitamin Drop has more than 85,000 cumulative reviews from global customers, and 93% customer satisfaction. By stabilizing pure vitamin C, the Vitamin Drop can be used even for sensitive skin . Experience clear and transparent skin every day.
