If you have spent any time researching skin treatments in London recently, you have almost certainly come across Rejuran — a Korean-developed injectable treatment that has rapidly become one of the most requested skin quality treatments at clinics across the capital. At Dr L'Art, we are an official UK partner for Rejuran Korean Polynucleotides, and Dr Dianni has welcomed the Rejuran headquarters and Chief Medical Officer team to the clinic on multiple occasions as part of this partnership.

What Is Rejuran?

Rejuran is an injectable treatment containing polynucleotides (PDRN) — fragments of DNA, typically derived from purified salmon DNA, that are biocompatible with human tissue. Rather than adding volume like a traditional filler, Rejuran works to repair and regenerate the skin at a cellular level, improving skin quality, texture, hydration and resilience over a course of treatments.

How Does Rejuran Work?

Once injected into the skin, polynucleotides support tissue repair by stimulating fibroblast activity (the cells responsible for producing collagen), reducing inflammation, and improving the skin's own regenerative capacity. This makes Rejuran particularly effective for improving overall skin quality — think fine lines, dullness, dehydration and a compromised skin barrier — rather than targeting volume loss specifically.

Why Has Rejuran Become So Popular in London?

Rejuran's popularity has grown for several reasons: it delivers genuinely natural-looking improvement without adding visible volume, it suits a wide range of skin concerns and ages, and it has strong roots in South Korea's advanced skincare and aesthetic medicine culture — a market widely regarded as a global leader in skin innovation. Dr Dianni's own advanced training in South Korea's Gangnam district gives her particular expertise in delivering Rejuran using authentic technique and product sourcing, which matters given the rise of counterfeit polynucleotide products in the unregulated market.

What Can Rejuran Treat?

●       Overall skin quality, texture and radiance for dull, tired-looking skin.

●       Fine lines and early ageing, particularly around the eyes and cheeks.

●       Post-acne or textural scarring, as part of a broader scar treatment plan.

●       Skin dehydration and barrier support, particularly relevant for menopausal or environmentally stressed skin.

●       Under-eye rejuvenation, using specifically formulated eye-area polynucleotide products.

What Should You Expect From Rejuran Treatment?

Rejuran is typically delivered as a course of several sessions spaced a few weeks apart, with results building gradually as the skin regenerates. Most patients experience mild swelling or small bumps immediately after treatment, which settle within a day or two, followed by a steady improvement in skin texture, tone and resilience over the following weeks.

Frequently Asked Questions

Is Rejuran the same as dermal filler?

How many Rejuran sessions are usually needed?

Most treatment plans involve a course of three sessions spaced several weeks apart, though this varies depending on individual skin concerns.

Is Rejuran safe?

When delivered by a qualified medical practitioner using genuine, licensed product, Rejuran has a well-established safety profile.

Yes, Rejuran is often combined with biostimulators, dermal fillers or Ultherapy PRIME as part of a comprehensive skin rejuvenation plan.
