How to Apply

For evening use.

If you have younger skin or are new to retinol, it's best to start slowly to build up your tolerance. Start by using the serum two nights a week and gradually increase the frequency as your skin adjusts. GEZEITEN retinol is highly potent yet microbiome-friendly, delivering targeted results at the cellular level while being gentle on your skin.

STEP 1
Gently pat face and neck dry after cleansing. Squeeze a few drops of serum into the palms of your hands and gently press into skin, face, neck and décolleté.

STEP 2
Follow with GEZEITEN Face Cream Night to complete your skincare routine.


Tip: The use of additional serums is neither necessary nor recommended. Our innovative approach provides a highly concentrated formulation that contains all the active ingredients the skin needs during the night.
