d'alba Piedmont DA004 Serum vs SeoulCeuticals PDRN Serum
Both serums sit right around the $20 mark and carry strong review totals, yet they take very different approaches to anti-aging skincare. The d'alba Piedmont DA004 is a niacinamide-based aerosol spray serum in a generous 3.38-ounce bottle, rated 4.4 stars across more than 43,000 reviews. The SeoulCeuticals PDRN Serum leans on polydeoxyribonucleotide, a salmon DNA-derived ingredient that has drawn attention for its potential to support skin recovery and the appearance of skin texture, backed by 27,600 reviews at the same 4.4-star rating. At $19.99 versus $20.99, the price difference is negligible, so the real decision comes down to ingredient philosophy and format preference.
Quick winner
The d'alba DA004 edges ahead for most shoppers on sheer volume of real-world feedback (43,200 reviews vs 27,600) and a larger bottle for nearly the same price, though the SeoulCeuticals PDRN Serum is the stronger pick if you specifically want a PDRN-based formula.

The SeoulCeuticals PDRN Serum is priced at $20.99 for a 1-ounce bottle and is built around polydeoxyribonucleotide, commonly referred to as PDRN or salmon DNA. PDRN has attracted growing interest for its role in supporting the appearance of skin repair and overall skin quality. At 27,600 reviews and a 4.4-star average, it has a substantial and consistent track record with buyers. The smaller bottle size is the main practical limitation compared to the d'alba, though the ingredient focus is more specialized and may appeal to those specifically researching PDRN.
Buy this if: Shoppers who have been specifically researching PDRN or salmon DNA serums and want a straightforward, focused formula built around that ingredient. Those who prioritize ingredient novelty and are comfortable with a smaller 1-ounce bottle at a slightly higher per-ounce cost. People whose current routine lacks a recovery-focused serum and who want to target the appearance of skin texture and resilience.

What is the main ingredient difference between these two serums?
The d'alba Piedmont DA004 lists niacinamide as its key ingredient, a form of vitamin B3 that may help with the look of enlarged pores and uneven skin tone. The SeoulCeuticals PDRN Serum is centered on polydeoxyribonucleotide, a salmon DNA-derived compound that has attracted attention for supporting the appearance of skin repair and quality. The two serums are targeting different aspects of anti-aging skincare, so your ingredient priority should guide the choice.
How do the sizes compare, and does that affect value?
The d'alba DA004 comes in a 3.38-ounce aerosol bottle at $19.99, while the SeoulCeuticals PDRN Serum is 1 ounce at $20.99. On a per-ounce basis, the d'alba is the clearer value. That said, a 1-ounce bottle is a standard size for serums, so the SeoulCeuticals is not unusually small for the category. If you use serums sparingly, 1 ounce can still last several weeks.
Which serum has more buyer feedback to rely on?
The d'alba Piedmont DA004 has over 43,200 reviews compared to roughly 27,600 for the SeoulCeuticals PDRN Serum. Both share a 4.4-star rating, but the larger sample size behind the d'alba gives that rating more statistical reliability. The SeoulCeuticals total is still substantial and not a red flag, just a smaller pool.
Can either serum be used with other actives in a routine?
Niacinamide in the d'alba is generally considered easy to layer and is compatible with most skincare actives, including hyaluronic acid, peptides, and even low-concentration acids. PDRN-based serums like the SeoulCeuticals are typically positioned as recovery or calming steps, which makes them a natural fit after exfoliating treatments when the skin barrier needs support. Neither product lists any specific contraindications in available specs. When in doubt, apply one at a time and allow each layer to absorb before the next.
