FAQ
Common questions
Why is INFUSE the first step?
Hydration comes first. When your skin is properly hydrated, every active applied after it absorbs into a plumped, prepared surface rather than dry, barrier-compromised skin. The sequence is the mechanism.
Is PDRN the same as Rejuran injections?
No. Rejuran is an injectable PDRN treatment delivered in clinics. INFUSE uses topical PDRN as a daily serum layer. They serve different purposes — one is a clinical procedure, the other is a daily foundational step.
How often should I use INFUSE?
Twice daily — once in your morning routine and once at night, as the first step each time. Consistency is what drives visible hydration and barrier support, not occasional heavy application.
Can INFUSE replace my moisturiser?
No. INFUSE is a hydration serum, not an occlusive moisturiser. It attracts moisture; it doesn't seal it in. Follow with your moisturiser (and SPF in the morning) to lock in what INFUSE delivers.
Is PDRN vegan or salmon-derived?
PDRN (polydeoxyribonucleotide) is a DNA-derived skincare ingredient. For the specific source of the PDRN in INFUSE, review the full ingredient disclosure on our ingredients page or contact us at support@the3dropsystem.com.
