Dr Reju All PDRN Cream and Serum Review

A research-based review of Dr Reju All PDRN cream and copper peptide serum, including current 1,200 ppm claims, version differences and evidence limits.

Dr Reju searches can refer to Dr Reju All's PDRN skincare, but the product name needs checking. Dr Reju All, Dr Althea's Reju range and Rejuran-branded products are not interchangeable. A similar-sounding name is not proof of a shared formula or clinical evidence. The brand's name is also written Dr. Rejuall, Dr. Reju-All or simply Rejuall on UK retailer listings, so a search for the Dr Rejuall PDRN cream usually means the Advanced PDRN Rejuvenating Cream covered here.

The current official Dr Reju All range includes a PDRN moisturising cream and a copper peptide serum. This is a research-based assessment, not a hands-on test or independent verification of the manufacturer's clinical claims.

What the current cream page states

The official 30 ml Advanced PDRN Rejuvenating Cream page identifies salmon-derived PDRN at 1,200 ppm and highlights collagen, hyaluronic acid, panthenol and allantoin.1 It is therefore inaccurate to say the brand never discloses a concentration.

On the same finished-product basis, 1,200 ppm is 0.12%. A raw-material purity claim is a different measurement and should not be presented as the percentage of PDRN in the tube.

The 30 ml page is the version reviewed here. Retailers may list other sizes, including older stock. Confirm the exact product rather than transferring every statement automatically across 20 ml, 30 ml and larger packs.

Brand testing deserves a careful reading

Dr Reju All's page presents test claims about moisture, redness, blemishes and barrier-related outcomes.1 A fair review should acknowledge them rather than saying no tests exist.

We have not independently reviewed complete study protocols or reproduced the findings. Claims of an optimal concentration therefore remain manufacturer claims, not a universal conclusion that 1,200 ppm is better than every other amount.

The measured endpoint matters too. A short-term moisture reading, an artificial-skin experiment and a clinical improvement after a procedure are not interchangeable. Nor does a product's pharmacy positioning establish that it is licensed as a medicine.

The copper peptide serum is a separate formula

The official range page describes the Advanced PDRN Copper Peptide Serum with 1,200 ppm PDRN and a multi-peptide blend.2 Retail and ingredient-database pages provide further formula information, including a secondary list with hinoki and chamomile oils.3 4

Because these details come from different sources, check the pack before relying on a fragrance or allergy claim. Do not assume that enjoying the cream means the serum will suit you equally well.

Adding copper peptides also does not automatically prove a better result. A meaningful comparison would need trials of the finished products, not a count of how many active-sounding ingredients each contains.

Choose the step rather than the brand story

If you need a moisturiser, the cream is the relevant format. If you already have one and want an optional serum, assess the serum separately. There is no requirement to buy both or to replace an effective routine with a matching set.

Compare the complete formula, delivered price and how much product you need for ordinary use. We have not measured texture or tolerability, so do not award a best-for-sensitive-skin label or promise a specific glow.

Source and safety checks

The cream's official salmon description is relevant for fish allergy and animal-free preferences.1 Seek product-specific advice if you have a known allergy; a home patch test cannot establish that a potentially allergenic product is safe for you.

Use cosmetics on intact skin according to the pack. The official cream page itself cautions against use on wounds.1 Do not interpret post-procedure marketing elsewhere as permission to apply it to freshly punctured skin without the treating clinician's guidance.

Stop if a product causes persistent irritation. For pregnancy, a diagnosed skin condition or a complex prescribed routine, obtain advice that considers the full formula rather than PDRN alone.

Our verdict

Dr Reju All offers more explicit PDRN information than the original retailer-only descriptions suggested. That is useful transparency, but it is not independent confirmation of all efficacy claims. Evaluate the cream and serum as different cosmetics and keep medical-treatment expectations separate.

For broader choices, see the PDRN cream guide and PDRN product overview.

Common questions

How much PDRN does the cream claim

The current official 30 ml page states 1,200 ppm. Verify the version you buy.1

Is Dr Reju All the same product as Dr Althea Reju

No. Match the full brand and product name before comparing ingredients or claims.

Does pharmacy branding prove it works

No. The relevant evidence is the study of the actual product for the claimed outcome.

Do I need the cream and serum together

No. Choose according to the step your routine needs, not a requirement to use a whole range.
