How long does DefenAge 8-in-1 BioSerum take to work?
DefenAge describes the product as providing some immediate improvements in smoothness and radiance, while longer-term visible rejuvenation develops with consistent use. The brand has also published clinical and product materials discussing results over several weeks.
Why is the 8-in-1 BioSerum layered last in a skincare routine?
DefenAge recommends applying 8-in-1 BioSerum as the final skincare step because it contains the brand's highest concentration of Age-Repair Defensins. Applying your other treatment products first allows them to be used before the BioSerum. In the morning, apply sunscreen after the BioSerum.
