How Often Should You Use PDRN? A Routine Guide for Australian Skin

~5 minute read · Updated April 2026

The short answer is: most people use topical PDRN twice a day, every day. Morning and night. The longer answer involves your skin type, your climate, whatever else you're layering on, and whether you actually remember to do skincare before bed (no judgement, most of us don't half the time).

This is the practical, no fluff version. If you want to understand what PDRN is before diving into how to use it, start with our full guide: What is PDRN? The Complete Australian Guide to Salmon DNA Skincare.

The baseline routine

If you're starting fresh and want the simplest possible answer, here it is:

  1. Cleanse with something gentle. No scrubs, no foaming volcanoes.
  2. Pat skin mostly dry. Leave it a little damp, not dripping.
  3. Apply your PDRN serum. Press it gently into the skin. Don't rub. Let it settle for 20 to 30 seconds.
  4. Moisturiser on top to seal everything in.
  5. SPF in the morning. Every morning. This matters more than any serum you will ever buy.

Do this twice a day if you can. Once a day if mornings are chaos. PDRN is a forgiving ingredient. It rewards consistency over perfection.

The layering order when you have other actives

Most people aren't just using PDRN and nothing else. You've probably got a vitamin C, a retinoid, maybe a hyaluronic acid, possibly an exfoliating acid you use once a week when you remember it exists. Here's how PDRN fits in with all of them.

With hyaluronic acid

Apply PDRN first, then hyaluronic acid on top. PDRN is lighter and absorbs faster. HA sits closer to the surface and locks moisture in. They complement each other beautifully and there's no waiting time between them. We've written a full comparison if you want the detail: PDRN vs Hyaluronic Acid.

With vitamin C

Use vitamin C in the morning (it pairs well with SPF for antioxidant protection) and apply your PDRN straight after it. Order: cleanse, vitamin C, PDRN, moisturiser, SPF. At night, skip the vitamin C and just use PDRN on its own.

With retinoids

This is where people get nervous, and fairly. Retinoids can be irritating, especially in the first few weeks. The safest approach is to alternate nights. Use your retinoid one evening, use PDRN the next. On retinoid nights, you can still use PDRN in the morning. Once your skin has adjusted to the retinoid (usually after 4 to 6 weeks), you can layer PDRN underneath the retinoid on the same night if your skin tolerates it.

With exfoliating acids (AHAs, BHAs)

Use your acid on a different day or at a different time of day. If you exfoliate in the evening, use PDRN the following morning. Don't layer them directly on top of each other. This isn't because they react badly together, it's just about not overwhelming your skin with too many actives at once.

With niacinamide

No conflicts at all. Layer in whatever order you like. They play nicely together.

Morning vs night: does it matter?

Not dramatically. PDRN works the same way regardless of what time you put it on. That said, there are small practical differences:

Morning: PDRN sits nicely under SPF and makeup without pilling. It's lightweight enough that it won't make your sunscreen slide around. If you're only going to use it once a day and you're choosing between AM and PM, morning is slightly more practical because you're more likely to actually do it as part of your getting ready routine.

Night: Your skin does most of its repair work overnight, so layering on supportive ingredients before bed makes intuitive sense. Night is also when most people use their heavier actives (retinoids, thicker moisturisers), and PDRN layers well underneath all of those.

Both: The best option if you can manage it. Twice a day gives you the most consistent exposure, which is where PDRN's cumulative benefits come from.

Adjusting for Australian climates

Australia is not one climate. Your routine should reflect where you actually live.

Brisbane and tropical Queensland: Humidity is your friend here. PDRN absorbs well in humid conditions, and you can often get away with a lighter moisturiser on top (or skip the heavy night cream entirely in summer). The main thing is not skipping SPF because the UV is relentless, even on overcast days.

Sydney and temperate coasts: You'll probably want the full routine year round. Summer is humid enough that PDRN absorbs easily; winter gets dry enough that you'll want a proper moisturiser sealing everything in.

Melbourne and southern states: Winter is where your skin will notice the difference. The dry, cold air strips moisture fast, so doubling up on PDRN morning and night makes the biggest difference during the colder months. In summer, once a day might feel like enough.

Perth and dry climates: Similar to Melbourne's winter advice, but year round. Dry air means your skin is always losing moisture, so consistent twice daily application and a good moisturiser on top are especially important here.

After a clinical treatment

If you've just had a professional microneedling session or a similar clinical facial, your skin is temporarily more sensitive and more absorbent. Your aesthetician will give you specific aftercare instructions, and you should follow those first.

Generally speaking, most professionals are comfortable with clients using a gentle PDRN serum in the days following a treatment, but the timing and frequency should come from your clinician, not from us. We've written a full aftercare guide if you want more detail: Microneedling Aftercare: What to Do in the 48 Hours After Your Appointment.

Common mistakes

Applying to completely dry skin. PDRN absorbs better on slightly damp skin. After cleansing, pat dry but don't wait until your face feels tight and dry before applying.

Skipping moisturiser. PDRN is not a moisturiser. It's a serum. You still need something on top to seal in the hydration. Even a light one.

Expecting overnight results. PDRN is a cumulative ingredient. Most people start noticing a difference in the look and feel of their skin after 3 to 6 weeks. Before that it just feels like a nice, lightweight serum. That's normal. Keep going.

Using too much. If you're using VITARAN capsules, one capsule per application is the right amount. No need to double up. More product doesn't mean faster results, it just means waste.

Our recommended starting point

VITARAN capsules are our pick for building a PDRN routine. Each capsule is a single dose, so there's no guessing, no measuring, and no contamination risk from dipping fingers into a jar. Open one capsule, press the contents into your skin, moisturise, and you're done. It takes about 30 seconds.

If you're also working with an aesthetician and using PDRN during clinical treatments, Curenex is the product designed for that setting. Your clinician will handle the application during the appointment, and you can continue with VITARAN at home between sessions.

The short version

Use PDRN once or twice a day, on slightly damp skin, before your moisturiser. Layer it under hyaluronic acid if you use both. Alternate with retinoids until your skin adjusts. Don't skip SPF. Give it at least a month before judging the results. Adjust your moisturiser weight based on your climate and the season. And don't overthink it. Consistency beats complexity every time.
