New Product Launch

As more people visit aesthetic dermatology clinics for skin issue treatment and maintaining healthy skin, a new product featuring the popular skin-conditioning ingredient “azelaic acid” has been introduced.

Brand Background

‘DRX’ is a medical-exclusive brand that has pursued quality, usability, and ease of continuous use based on feedback from doctors and healthcare professionals who work directly with patients’ skin in clinical settings. Since launching the azelaic acid cream ‘AZA Clear (R)’ in 2011, the company has accumulated over 15 years of expertise and formulation technology related to azelaic acid.

Product Features

Azelaic acid is a poorly soluble ingredient that is difficult to dissolve in both water and oil, requiring extremely high formulation technology, while its unique texture has also been a major challenge. The newly launched ‘DRX AZA Clear Serum’ is a notable product developed to address these issues by focusing on the texture of azelaic acid and utilizing proprietary technology.

Its biggest feature is that it incorporates “azelaic acid” itself—not a derivative—as a skin-conditioning ingredient while achieving a serum dosage form that is easy to blend into the entire face. With a smooth, spreadable texture, it is designed to be seamlessly integrated into daily skincare routines. This product is expected to be a reliable ally for those undergoing aesthetic medical treatments, as well as for individuals seeking to balance clinical treatment with home care, helping to maintain healthy skin every day.

Availability

The ‘DRX AZA Clear Serum’, combining expertise from specialized institutions and pharmaceutical technology, is available at open price starting July 21 at authorized hospitals and clinics nationwide. Purchase requires a medical consultation or counseling at a medical institution, so interested individuals should check the official website for authorized locations.
