Useful if: choose it if you want a PDRN product in a spray format rather than a conventional dropper serum. Shake before use and spray with the eyes closed.
The useful difference is the delivery system. This is a lightweight mist rather than a dropper serum, and the product directions say to shake the bottle so the water and oil layers mix before spraying.
That makes it easier to compare with other mist formats on Skincare Lab UK. The spray can be used as a leave on layer, but it does not automatically replace moisturiser if your skin still needs a more substantial final step.
The ingredient list includes collagen water, niacinamide, sodium DNA, glutathione, rose water and several peptides. Fragrance is also listed, so check the current pack if fragrance matters to you.
Those ingredients describe how the product is formulated. They do not make topical PDRN equivalent to injectable polynucleotide treatments.
Shake well, close your eyes and spray evenly over the face, then allow it to absorb. It can sit after cleansing or another light hydrating step, or be used later in the day as a mist if that suits your routine.
If you already use several treatment serums, the main buying question is whether the spray format adds something useful rather than simply duplicating another hydrating step.
