3-IN-1 Duo Pro is a unique anti-aging skincare that fuses the power of two ultra-concentrated formulas – Anti-Aging Booster Serum and our legendary 3-IN-1 Anti-Aging Cream for all skin types – in a single bottle. In perfect synergy, the serum and the cream infuse the skin with a youth-boosting treatment: the skin is firmed and deeply moisturized, wrinkles are smoothed, and the complexion reaches its optimal radiance. The effectiveness of this high-performance duo is the result of an exceptional blend of active ingredients based on aesthetic medicine.
