A 34 g hydrogel sheet with glycerin, niacinamide and gel-forming ingredients. COSRX lists Sodium DNA and Hydrolyzed DNA. The ingredient declaration confirms they are present and gives no finished-mask comparison with the matching serum or toner.
A fabric sheet mask in a 350 g tub. The maker's list starts with water and glycerin and includes panthenol, squalane, several ceramides and Sodium DNA. It fits an optional short masking step. The ingredient declaration cannot establish the effect of daily use.
A 34 g hydrogel sheet with glycerin, niacinamide and gel-forming ingredients. Biodance lists Sodium DNA along with caviar and salmon egg ingredients. The list establishes their presence and leaves their contribution to the mask’s effects uncertain.
A single-use hydrogel mask with salmon-derived sodium DNA, niacinamide, hydrolysed collagen and peptides. It provides an intensive temporary hydration and glow step rather than a necessary daily routine product.
A PDRN mask mainly gives a short-term hydration and plumping effect from its essence and the occlusion of the sheet or gel. No clinical studies have been published on specific PDRN masks, so treat one as an occasional hydration step rather than a treatment.
Most PDRN research concerns injected or medical preparations. Evidence for PDRN applied to intact skin is early and formulation-specific, so a product's whole formula, texture and your tolerance matter more than a headline PDRN claim.
