Wed, 06 May 2026 16:00:00 GMT

PDRN molecules are 50,000–1,500,000 daltons. Your skin barrier blocks anything over 500. So how much of your salmon DNA serum actually gets in? The answer depends entirely on the delivery method — and the penetration gap between injectable, microneedling, and topical is massive.
