Choose two products to compare.

The database holds 644 rows but 613 distinct products. Where a product has more than one record, the picker groups them under one entry and discloses the disagreement.

Side by side

The comparison table

One row per dimension, one column per product. Every value comes from the selected record; nothing is computed except the position percentage and the ladder placement.

Concentration

The concentration ladder

Of the 93 products that print a concentration, 62 print less than 0.1% and 78 print less than 1%.

This is a ladder of what brands claim, not of what is in the bottle. A higher claim is not a better product. The faint bars are the dataset-wide distribution of the printed claims; the marks are the products selected here. The 0.1% line is the concentration used in the only human RCT and the only human in vivo permeation measurement of topical PDRN (PMID 42430369).

Circle marks are ppm or ppb claims placed by pure unit conversion. Diamond marks are percentage claims placed assuming density 1.0. A non-standard unit cannot be placed and appears in the panel beside the chart.

Ingredient order

INCI position reading

Where the DNA sits in the list, read against the label’s descending order. Ingredient lists in this dataset run from 2 to 125 items.

24 of 644 products place DNA in the first three ingredient positions.33 place it last.Position is a signal, not a measurement.

Select at least two products to read their INCI positions.

Differences

What actually differs

Only the dimensions where the selected records disagree. This panel does not rank the products and does not recommend one.

Select at least two products to compare. Nothing is ranked or recommended here.

Overlap

Shared ingredients

What the selected lists have in common — and whether they share the DNA ingredient at all. Shared words are not shared amounts.

Select at least two products

The shared-ingredient reading appears once there is something to compare.

Limits

Read the comparison as a comparison of labels

Standing limits

This compares labels, not formulas. Nobody measured the bottles.
A brand-printed concentration is a claim, never a measurement.
Not determined does not mean low. It means the label gives no way to tell.
The 0.1% research reference comes from a specific preparation (≤850 kDa, ~1,200 bp, ≥96% purity) in a specific vehicle. It is not extrapolated to the market.
Only 24 of 644 products place DNA in the first three positions, and 33 place it last.
The database has no price field, so there is no price comparison, no “best value” verdict and no recommendation.
Nothing here is medical advice or a therapeutic claim.

Exchange two selected columns without changing the selection.

Clear the comparison

Remove every product and start again. The ladder keeps its dataset-wide distribution.
