Do You Actually Need PDRN in All Your Skincare Products?

Do You Actually Need PDRN in All Your Skincare Products?

PDRN is everywhere right now.  Serums, essences, creams, masks—you can now find it in almost every step of a skincare routine. But do you actually need PDRN in all your skincare products?

No.

PDRN can be a powerful ingredient on its own. You don't need a PDRN toner, essence, serum, cream and mask for it to be worthwhile. One well-formulated product can be enough.

So, if PDRN is already doing the work, what should you actually look for when choosing a PDRN product?

Wait—Is PDRN Actually an Active?

If you've been following our Instagram or TikTok, you'll know one of our favourite skincare reminders:

More actives doesn't mean better.

So where does PDRN fit?

Yes, PDRN is an active skincare ingredient. But it isn't an active in quite the same way as retinoids, AHAs or BHAs.

Retinoids and exfoliating acids are typically used to influence processes such as cell turnover or exfoliation, and they can cause irritation if overused.

PDRN is generally used for a different purpose—supporting skin conditioning, hydration and the appearance of healthier-looking skin. It isn't usually something you need to cycle or introduce cautiously simply because it's an “active.”

So if you're already using retinol, retinal, acids or other treatment products, you don't automatically need to stop them when adding PDRN.

PDRN can sit alongside your existing routine rather than requiring you to rebuild it.

As always, look at the full formulation of the individual product and consider the other actives you're already using.

Can PDRN Be Used With Other Actives?

Generally, yes.

PDRN is often formulated alongside other familiar skincare ingredients. These combinations can complement different skin concerns—but they aren't required to make PDRN worthwhile.

  • PDRN + Hyaluronic Acid
    → a good direction if hydration is your priority.
  • PDRN + Peptides
    → useful if you're focused on firmness and visible signs of ageing.
  • PDRN + Retinal
    → a good pairing if you're targeting fine lines, loss of firmness or sagging skin.
  • PDRN + Niacinamide
    → a good option if visible pores, excess oil or uneven skin tone are among your main concerns.

And if a PDRN product doesn't contain any of these? That's perfectly fine too.

PDRN doesn't need a supporting cast to be a good ingredient.

These additional ingredients simply allow a formula to address other concerns at the same time.

PDRN Isn't Just About the Number on the Bottle

When comparing PDRN products, you may come across claims about ppm, molecular size and delivery technology.

These are interesting things to understand, but don't treat them as a simple “bigger is better” equation.

What does PDRN ppm actually tell you?

PDRN is often listed in ppm (parts per million).

A higher ppm means there is more of the stated PDRN in the formula. But concentration alone doesn't tell you how effective the finished product will be. It doesn't tell you everything about the formulation, stability, delivery or how the product performs on skin.

So while 10,000 ppm contains more PDRN than 5,000 ppm, it doesn't automatically mean the 10,000 ppm product will give you better results.

What about molecular size?

You may also see products highlighting smaller molecular size or molecular weight. Molecular size can influence how an ingredient behaves and interacts with the skin, but smaller doesn't automatically mean more effective.

With PDRN, you're also dealing with DNA fragments of different sizes, so it's not as simple as saying that the smallest fragments are always the best. A smaller molecular size is one characteristic of a formulation—not a guarantee of superior results.

And what about delivery systems?

The way PDRN is formulated can also matter. The vehicle, delivery technology and overall formulation can influence things such as stability, release and how the ingredient behaves on the skin.

But again, don't assume that the most complicated-sounding delivery technology automatically means the better product.

PDRN isn't a numbers game.

A higher ppm, smaller molecular size or more advanced-sounding delivery system doesn't automatically make one PDRN product better than another. What matters is the finished formulation, the product's intended purpose and whether it makes sense for your skin.
