REJURAN Dual Effect Ampoule
Ingredient analysis and how the ad lines read
Read on 2026-09-21
What is this product?
A brightening and wrinkle improvement double functional ampoule built around hydrolyzed DNA derived ingredients, niacinamide and adenosine, with ceramide and humectant support for barrier friendly hydration. Choose it for functional brightening and anti-aging care in a fragrance free formula.
What makes it different?
The formula carries DNA derived ingredients mid-list, with niacinamide sitting eighth and adenosine at 26, and the page names a Korean testing institution. It also layers arbutin, ceramide NP, urea and cholesterol, so brightening claims rest on more than one functional agent. No essential oils or declared fragrance appear in the 40 item list. Concentrations and pH are not printed on the brand page.
