PDRN serum and mask help
Answers for the Helloskin PDRN Serum, PDRN overnight mask and salmon DNA starter kit routine.
PDRN
What is PDRN in skincare?
PDRN sits in Helloskin's salmon DNA skincare system, including the PDRN Serum, overnight mask and starter kit routine.
What is PDRN in skincare?
PDRN stands for polydeoxyribonucleotide. In skincare, it is often described as salmon DNA skincare because it is commonly salmon-derived. Helloskin uses PDRN/Sodium DNA in topical cosmetic formulas designed for hydrated, rested-looking, more comfortable-feeling skin.
Is Sodium DNA the same idea as PDRN?
Sodium DNA is the INCI name customers may see in formulas that discuss PDRN-style skincare. Helloskin keeps the product education plain-English so shoppers can connect the ingredient list with the PDRN product story.
Products
PDRN serum, mask and starter kit
The serum is the daily step. The overnight mask is the 1-4 times weekly richer step. The starter kit brings the PDRN routine together.
When should I use PDRN Serum?
Use PDRN Serum after cleansing and before moisturiser. It suits routines focused on hydrated, rested-looking, bouncy-looking skin. If your skin is new to the formula, introduce it gradually.
How often should I use the PDRN overnight mask?
Use the PDRN overnight mask 1-4 times per week, depending on your skin and routine. It is designed as a richer overnight comfort step, not something you have to use every single night.
Do I need the PDRN serum and mask starter kit?
You do not need both products, but they play different roles. The serum is the daily PDRN step. The mask is the weekly overnight support step. The kit is best if you want a complete PDRN routine without guessing.
Compare
PDRN vs GHK-Cu
PDRN and GHK-Cu are both ingredient-led Helloskin systems, but they speak to different routine goals.
What is the difference between PDRN and GHK-Cu?
GHK-Cu is the copper peptide route for firmer-looking, smoother-looking skin. PDRN is the salmon DNA route for a hydrated, rested-looking complexion. If your routine is firmness-led, start with GHK-Cu Serum. If your routine is glow, comfort and bounce-led, start with PDRN Serum.
Can I use PDRN and GHK-Cu together?
Yes, many routines can include both, but introduce products gradually. You can keep one as the daily serum and use the other on alternate nights or as part of a mask routine if that feels easier.
