This highly concentrated night serum utilizes 2% retinal liposome technology (0.02% pure retinal) to accelerate cell turnover while minimizing the risk of irritation. Combined with fermented Black Rice extract, it works deeply to smooth fine lines, refine skin texture, and tighten pores. Its fluid texture absorbs instantly, leaving the skin firmer, clearer, and visibly rejuvenated within the first few weeks of use.
