Mediheal PDRN Derma Serum

What is this product?

Mediheal's PDRN Derma Serum is worth reading for one number and cautious about what that number means: sodium DNA, the ingredient PDRN branding rests on, is printed at 2 ppm, or 0.0002 percent, which is the only disclosed amount on a 44 ingredient label. The injectable PDRN literature the name borrows from uses milligram doses into the dermis, so nothing there transfers to this. What is likely doing the work instead is niacinamide at position 6, with adenosine at 25, and neither carries an amount or a published measurement. There is no 향료 entry, though hinoki and rose oils are printed at 26 and 31.

What makes it different?

Printing an amount at all is what separates this from its shelf, and Mediheal prints the one that undercuts its own front label: 2 ppm of sodium DNA. That openness is worth rewarding even as the figure decides against the claim. The rest of the formula is a competent barrier and hydration build rather than a treatment one, with squalane 9th, damask rose water 11th, panthenol 13th, sodium hyaluronate 30th and ceramide NP 43rd. Two essential oils at 26 and 31 supply the scent in place of a fragrance entry, which reactive skin should weigh. Nothing else on the label carries a number, and no pH is published.

Did the ad claims hold up?

We checked 3 lines this product advertises against the ingredient list and public documents. None of them hold up on their own. They are partly right at best.

Claims translated from Korean, originals preserved.

Each line is quoted as the brand published it, and each one was read on its own against the ingredient list and the documents the brand publishes.
