PDRN (polydeoxyribonucleotide) is a salmon-DNA-derived ingredient used in K-beauty for hydration and a smoother, more comfortable-looking complexion. PDRN skincare most often comes as a PDRN serum, and it's easy to layer into a simple routine for dull-looking or sensitive-feeling skin. Research on topical PDRN is still limited, so real-world reviews can help show how it feels in everyday use. On ingredient lists, PDRN is often labeled "Sodium DNA." If you have a fish allergy, check the label, and patch test first.

Feels drying on its own?
Layer a hyaluronic acid or ceramide moisturizer on top, or switch to a richer PDRN cream at night — use the serum AM/PM and seal with cream after.

LABO-H
Scalp Strengthening Capsule Treatment

Pros
I bought this for scalp concerns and as a preventative measure against hair loss. The ingredients are gentle, and I really appreciated that I could apply it directly to my scalp. It has a minty scent that gives off a refreshing, cooling sensation.

Prestige Hydrogel Mask

Pros
After removing my makeup, I tried out this hydrogel face mask! As fall arrived, I knew my skin was getting drier and I needed to start using masks regularly. The mask adheres really well to my skin, and it feels much more bouncy and elastic compared to regular sheet masks! After using it, my skin feels hydrated and smooth, so it's great for managing dry and dull skin. As my skin gets filled with hydration, my skin texture becomes more refined, and my makeup application the next day feels like it goes on better too. Since I can do intensive hydration care conveniently at home, I'll definitely reach for this on days when my skin isn't looking its best!

Not necessarily, injectable PDRN has more established clinical research and better penetration than topical application, so topical products likely deliver more modest effects than injectable treatments.
No they're different ingredient categories with different origins and mechanisms, though all three are newer 'regenerative' K-beauty ingredients marketed for similar repair and resilience benefits.
It's reasonable to expect soothing, hydrating and conditioning benefits, but independent clinical evidence for dramatic topical 'regeneration' claims is still more limited than the marketing suggests.
