Khalid Anwar

Clinical Pharmacist, UK

GPhC 2219283

Khalid Anwar is a clinical pharmacist in the UK and acts as clinical and evidence adviser to Korean PDRN. His role is to bring a pharmacist's habit of critical reading to cosmetic ingredient claims: separating independent research from manufacturer statements, noting when evidence comes from clinic injections rather than leave-on products, and flagging where product-specific evidence is thin or absent. Pharmacist training is not the same as dermatology expertise, and he is not a dermatologist or a hands-on product tester. Korean PDRN is a cosmetic information site, not a healthcare or medical treatment service; for a skin condition, speak to a pharmacist, GP or dermatologist.

Registration is self-declared and can be checked on the General Pharmaceutical Council public register by searching the name or registration number. Korean PDRN has not independently confirmed it against the register.

• PDRN for Rosacea: What the Evidence Says

  PDRN is not a rosacea treatment, and it has not been studied in people with rosacea, so we cannot say it is safe or well tolerated for this condition.

  Editorial research review

  Small studies suggest PDRN and polynucleotide injections may improve atrophic (depressed) acne scars, usually alongside lasers, microneedling or subcision.
