Formulated with an impressive 99.8% ingredients of natural origin, this innovative bi-serum combines cutting-edge biotechnology with the power of nature.

At the heart of the formula is Yon-Ka's exclusive [RE]NEW Technology, which combines two complementary retinol-like ingredients that work together to deliver visible skin-renewing benefits while respecting the skin's natural balance.

Upon application, the two phases blend into a luxurious, lightweight emulsion that combines the effectiveness of a serum with the comfort and nourishment of an oil.

What Makes This Different From Traditional Retinol?

Traditional retinol accelerates skin cell turnover, which can often result in:

• Redness and irritation
• Dryness and flaking
• Temporary sensitivity
• Increased photosensitivity to UV exposure

The Yon-Ka Retinol-Like Bi-Serum offers a gentler approach.

Using advanced plant-derived and biotechnological ingredients, it helps encourage skin renewal and refinement without the common drawbacks associated with retinol. This means many users can enjoy smoother, more radiant-looking skin without the discomfort often experienced during a traditional retinol adjustment period.
