Can You Use PDRN With Tretinoin or Adapalene?

Short answer: Yes, you can use PDRN with tretinoin or adapalene. There is no known interaction. Apply your retinoid at night on dry skin, then a PDRN moisturiser to help with dryness and peeling. Use sunscreen daily and avoid sunbeds. Do not use tretinoin or adapalene if you are pregnant or trying to conceive, and follow the leaflet for your specific medicine.

Can you use PDRN with tretinoin? This question often comes from people prescribed a retinoid for acne or ageing who want to keep their Korean skincare. Retinoids are among the best-evidenced skincare treatments, but they commonly cause dryness, redness and peeling, especially in the first few weeks. A gentle PDRN product can be a comfortable partner. This guide explains how to combine them, with practical steps to reduce irritation. To understand how the two ingredients differ, read is PDRN retinol.

Key takeaways

• No interaction between PDRN and tretinoin or adapalene is known.

• In the UK, adapalene (Differin) is a prescription-only medicine, applied at night[1].

• Up to 1 in 10 people using adapalene get dryness, irritation, burning or redness[1].

• The adapalene and tretinoin leaflets both say not to use them in pregnancy or when planning a pregnancy[1,2]. Advice on breastfeeding differs between products[1,2].

• PDRN skincare mainly adds hydration; evidence that it reduces retinoid irritation is limited[3,4].

Tretinoin, adapalene and PDRN compared

Tretinoin and adapalene are medicines. They change how skin cells grow and shed, which is why they help acne but also cause irritation. PDRN does not work like a retinoid. It is thought to signal repair through A2A receptors when injected[5], but in skincare its main proven role is hydration.

How to use PDRN with tretinoin or adapalene

1. In the evening, cleanse gently and wait until skin is completely dry.

2. Apply a pea-sized amount of your retinoid to the whole face, avoiding eyes, lips and nostrils.

3. Wait a few minutes.

4. Apply a PDRN cream or a PDRN serum followed by moisturiser.

5. In the morning, use a gentle cleanser, a PDRN gel-cream and sunscreen of at least SPF 30[6].

Follow your prescriber's instructions and the leaflet for your product above any general advice. The adapalene leaflet advises applying it at night before bed and avoiding sunlight and artificial UV light[1]. The Treclin leaflet also advises avoiding natural and artificial UV light and using SPF 30 or higher outdoors[2].

The sandwich method

If your skin is very dry or sensitive, try the "sandwich" method: a thin layer of moisturiser, then the retinoid, then more moisturiser. A PDRN cream can be one or both layers. This may reduce irritation, although it may also reduce how much retinoid reaches the skin. Ask your prescriber before changing how you use a prescribed medicine.

Starting a retinoid alongside PDRN

Starting slowly is a common approach for cosmetic retinol. For prescription products, follow the plan from your GP, dermatologist or pharmacist. Do not start several new products at once; add the retinoid first, then other changes.

What the evidence says about PDRN with tretinoin

Retinoids have strong evidence for acne and photo-ageing, and NHS guidance lists topical retinoids among the main treatments for acne[7]. Evidence on combining them with PDRN is very limited. There are no trials testing whether PDRN skincare reduces retinoid irritation.

One 2026 randomised split-face study in 31 women compared a 0.1% PDRN eye cream with 0.1% retinol in the same base over 28 days and reported greater improvement in under-eye wrinkles on the PDRN side[4]. It was small and short, several authors work for cosmetics companies, and it compared PDRN with cosmetic retinol, not prescription tretinoin. It does not show that PDRN can replace a prescribed retinoid. Large molecules like PDRN also penetrate intact skin poorly[3], so any benefit from a topical product is likely modest.

Practical tip: Dryness and peeling are most common in the first weeks of a retinoid and are a frequent reason people stop. A plain, fragrance-free moisturiser is the most important partner. A PDRN cream is fine if it suits you, but check it for fragrance and essential oils.

Who should take care

• Pregnancy or trying to conceive: do not use tretinoin or adapalene[1,2]. The Treclin leaflet advises contraception during treatment and for one month after stopping[2]. There are no data on PDRN skincare in pregnancy; ask your midwife or pharmacist before starting new products.

• Breastfeeding: the adapalene leaflet says it can be used but not applied to the chest[1]; the Treclin leaflet says not to use it while breastfeeding[2]. Check the leaflet for your product and ask your prescriber.

• Eczema or rosacea: retinoids can worsen these. Your prescriber may choose another treatment.

• Fish allergy: most PDRN is salmon-derived[5]; check the source.

• Using acids: avoid AHA or BHA on retinoid nights; see can you use PDRN with AHA and BHA.

When to get help

Speak to your pharmacist or GP if irritation is severe, if your skin blisters or swells, or if your acne is not improving. The adapalene leaflet advises seeing your doctor after three months of use[1]. For mild dryness, cutting back to every other night and using a richer moisturiser usually helps. For more on acne treatment, see will PDRN help with acne.

Can PDRN replace tretinoin?

No. Tretinoin and adapalene are prescription medicines with strong evidence. Topical PDRN has early and limited evidence, mostly for hydration. If you cannot tolerate a retinoid, ask your prescriber about alternatives such as azelaic acid, rather than substituting a cosmetic. Our PDRN vs retinol and actives comparison explains where each fits.

How long does retinoid irritation last?

Dryness, redness and peeling are usually worst in the first few weeks, sometimes called the retinisation period. For most people they ease as skin adapts. Acne can sometimes look slightly worse early on before improving. Using a gentle, fragrance-free moisturiser, such as a PDRN cream, and introducing the retinoid slowly can help you get through this phase. If irritation is getting worse rather than better after a month, speak to your prescriber.

Can you use PDRN injections with tretinoin?

Clinics often ask you to pause topical retinoids for a few days before and after facial injections or microneedling. Follow your clinic's advice and tell them about every prescribed cream you use. If you have recently taken oral isotretinoin, many clinics will delay procedures; ask your dermatologist. See are PDRN injections safe for more.

The bottom line

You can use PDRN with tretinoin or adapalene. Apply the retinoid at night on dry skin, then a PDRN moisturiser, and use sunscreen every morning. PDRN may make the routine more comfortable, but it is not proven to reduce irritation and it does not replace a prescribed treatment. Do not use prescription topical retinoids in pregnancy.

FAQs

Should I apply PDRN before or after tretinoin?

Usually after. Apply tretinoin to dry skin, wait a few minutes, then PDRN moisturiser.

Can PDRN stop retinoid peeling?

It may help skin feel more comfortable, but there is no trial evidence that it prevents peeling.

Can I use PDRN and Differin in the same routine?

Yes. Use Differin at night as prescribed and add a PDRN cream afterwards[1].

Is PDRN safe to use with tretinoin in pregnancy?

No. Tretinoin should not be used in pregnancy or when planning a pregnancy[2]. Speak to your GP or midwife.

Can I use PDRN injections while on tretinoin?

Tell your practitioner. Many clinics ask you to pause retinoids for several days before and after facial procedures.
