🧴 Product Questions
What is PDRN and what does it do? PDRN (Polydeoxyribonucleotide) is a DNA-derived ingredient originally used in regenerative medicine. In skincare it deeply hydrates, supports collagen production, and helps visibly firm and smooth the skin — making it especially powerful for the delicate under-eye area.
Is this serum safe for sensitive skin? Yes. The formula is designed for all skin types including sensitive skin. As with any new skincare product we recommend doing a small patch test on your inner arm before applying to your face.
How do I apply the serum? Apply a small amount using your ring finger — it's your gentlest finger — and gently tap around the under-eye area morning and night after cleansing. Less is more with this serum.
How long before I see results? Most customers notice improved hydration and brightness within the first 1–2 weeks. For firming and visible line reduction, we recommend consistent use for at least 30 days.
Can I use this with my existing skincare routine? Absolutely. Apply it after cleansing and toning, before your moisturizer. It layers well with most serums and creams.
