Retinol-Like Bi-Serum | Yon-Ka Paris

Retinol is the most searched skincare ingredient for good reason, but irritation, redness, and sensitivity have kept a huge portion of people from ever actually benefiting from it. The Yon-Ka Paris Retinol-Like Bi-Serum delivers retinol-level renewal through a 100% natural, biotechnology-derived complex of biomimetic microalgae and active fraction of mastic tree, two retinol-like actives that activate retinoid receptors and protect retinoic acid from degradation without the irritation that comes with conventional retinol. The result is 80% of deep wrinkles visibly filled, 92% smoother and softer skin, and tightened pores from first use, in a formula tested on and suitable for sensitive skin.
