Vitamin C Serum
[INQ. NO. 2311C35] First C Serum Pure Vitamin C 15%, since its inception, has sold over 24 million bottles, generating revenue exceeding 2.3 trillion won—a remarkable feat in the beauty industry. The product, encapsulated in a radiant yellow bottle, has successfully laid the groundwork for smoother international distribution of Pure Vitamin C.
Launched towards the end of 2022, this product primarily sells online. It is the culmination of extensive Vitamin C research conducted at LIZK’s R&D Center. Its most noteworthy feature is the enhancement of pure vitamin stability, which has effectively extended the shelf life to 24 months. This is a significant improvement over typical Vitamin C serums that tend to oxidize and lose potency quickly once opened.

The product boasts a generous 20ml volume housed in LIZK’s signature coated glass container, ensuring every last drop remains safe and easy to use. Since its first launch in 2015, the First C Serum has been selected as the winner of numerous awards for eight consecutive years.
Its high-potency pure vitamin C formula, innovative technology that allows morning application, and potent brightening and antioxidant effects have won it the love and recognition of consumers worldwide. LIZK’s relentless pursuit of excellence and continuous ingredient and efficacy upgrades based on their R&D Center’s research have set a new industry standard, extending the product’s shelf life to a groundbreaking 24 months.

Focus on skin absorption is paramount since even the best ingredients must penetrate deeply into the skin to be truly effective. Clinical trials conducted by specialized institutions have shown a 263% improvement in skin absorption depth with this product. Recently, the interest from international consumers in the First C Serum has been on the rise, paving the way for expanded global distribution and enabling consumers worldwide to experience the benefits of superior Vitamin C.

LIZK, established in 2011, embarked on a journey to restore the innate beauty in women aspiring for youthfulness. Since the debut of its Pink First C Serum in 2015, LIZK has maintained its strong foothold in the market, even earning the title of the nation’s serum. Recognized for its innovative technology, LIZK has been expanding its product line beyond just the First C Serum, showcasing its commitment to continuous research and development.
