Dr. Duve Medical 
Retinew Serum

The heart of the Retinew Serum is the active ingredient Retinew A16, also called herbal retinol. Because of its excellent tolerability, Dr. Stefan Duve was able to use it in a much higher concentration than retinol. This leads to accelerated cell renewal, the skin is regenerated and the complexion looks smoother, fresher and more youthful after only a few weeks. Hyperpigmentation is reduced even on sensitive skin. Retinew Serum is ideal for all those whose skin suffers from environmental damage and decreasing regenerative capacity. It is also ideal for the prevention of skin damage.

“Retinol is a highly effective anti-aging ingredient with which I am working very successfully. But some skin types can react with tension. In this case I recommend Retinew A16 as an alternative: It achieves comparable results, but has no unpleasant side effects.” - Dr. Stefan Duve.

- Intensive active ingredient concentrate with high-dose Retinew A16. It activates the skin renewal process, which makes it regenerate better.

- It stimulates collagen production in the skin* and softens wrinkles. The result: the skin surface appears visibly smoothed. The skin looks fresh, plumper and more youthful again.
