Celladix is a derma cosmetics brand that has grown through strong customer feedback and scientifically proven product performance. Despite the excellent quality, the brand struggled to convey a distinct identity in the market, with one popular item unintentionally standing in for the brand as a whole. Double D redefined the brand identity of Celladix by emphasizing its unique approach to product development through scientific research — ‘science-based creative solution’, and repositioned the brand as a true ‘Derma Creator’.

Celladix's new logo brings together the meaning behind its name—"the root of the cell"—and the scientific expertise of a dermocosmetic brand. The near-circular 'C' evokes the soft, resilient form of a cell, while the two overlapping 'l's introduce sharp, needle-like angles inspired by precise skin penetration. Balancing soft curves with incisive details, the typography conveys clarity and credibility while giving Celladix a refined and distinctive presence.

A Flexible Graphic System Inspired by the Form of a Cell
The graphic motif derived from the logotype visually expresses Celladix's philosophy of providing a ‘fundamental derma solution from the cell level’. The pattern, which resembles cellular division and expansion, communicates the brand's originality and problem-solving approach.

Double D developed a flexible yet consistent layout system that places the logotype and product information on the same plane in both vertical and horizontal layouts. In vertical layouts, the logo is positioned vertically along the right edge, while in horizontal layouts, it is placed at the bottom. This ensures visual consistency across a wide variety of formats.

Category-Based Color & Material Guidelines
The color system covers three main product categories: Medical Derma, Daily Derma, and Anti-aging. Medical Derma products are represented by neutral blues to emphasize trust and expertise, while Daily Derma uses bright, vivid colors to convey a clean and refreshing image. Purple and glossy materials are used for Anti-aging products to create a functional and sophisticated impression. The color system clearly distinguishes each category, while a consistent layout applied across all packaging reinforces a unified and cohesive brand image.

Through this project, Double D aimed to position Celladix as more than a brand with effective products — rather, as a brand with a unique presence in the derma cosmetics industry, grounded in scientific credibility. The new brand identity establishes a distinct presence that communicates both confidence and innovation, setting a new standard for what a derma cosmetics brand can represent.
