No.3 Blue Bio-Retinol serum

Refine visible pores with gentle retinol care

This serum is a next-generation skincare solution designed to address enlarged pores and uneven skin texture. Formulated with 1% RetinART™ and 2% STARENOL™, this serum offers retinol-like efficacy with minimal irritation, making it suitable for sensitive skin. The Blue Bio-Retinol Technology targets ten types of pore concerns, including sagging, roughness, and loss of elasticity, delivering a 3D pore-tightening effect for a smoother complexion.

Infused with 10% niacinamide, the serum regulates excess sebum production and improves the appearance of enlarged pores caused by overactive oil glands. The inclusion of 1% phyto-exosomes, signaling peptides, and fermented extracts strengthens the skin barrier and enhances pore-refining results. Clinically tested to show a 0.00 irritation index, this serum is safe for daily use without causing redness or stinging. After one week of use, users experienced a 40% reduction in pore area and a visible long-term tightening effect.
