FAQs
How does the ReGenerative Serum work?
Consortia Factors® is a patented complex produced by growing yeast together with plant stem cells. The active material is the metabolites, peptides, lipids and plant-derived exosomes these cultured cells produce. The cells are not alive in the finished formula.
ReGenerative Serum helps hydrate skin and improve the appearance of smoothness, firmness and radiance.
How often should I use the face serum?
For optimal results, we recommend applying the STEM ReGenerative Serum twice daily: once in the morning and once in the evening. This routine allows the bioactive ingredients to align with your skin’s natural rhythm, protecting and hydrating during the day, and supporting cellular renewal overnight.
Regular use visibly improves skin hydration, elasticity, and tone while fortifying your skin barrier over time. If you're new to using active skincare products or have sensitive skin, starting with once-daily use is perfectly fine. You can work up to twice a day as your skin acclimates to the formula.
Consistency is key. Think of this serum not just as a product, but as part of a regenerative ritual that restores your skin's harmony and resilience.
When will I see results from using the ReGenerative Serum?
In an independent 8-week study of ReGenerative Serum, 35 women aged 48–70 (mean age 62.8) used the serum twice daily. At week 8, 82.9% reported smoother skin, 82.9% reported firmer skin and 82.9% reported more radiant skin. No adverse events were reported during the study.

Is the face serum safe for sensitive skin?
