If you’re looking for a new skin treatment that can help repair, hydrate, and rejuvenate your skin from within, Rejuran might be just the solution! This popular K-Beauty skin injectable is gaining attention around the world for its collagen-boosting properties that work with the skin's natural healing processes to improve elasticity and strengthen the skin barrier.

What Is Rejuran?

Rejuran is a brand of Korean injectable skin regeneration treatment containing polynucleotides, which are DNA fragments derived from purified wild salmon DNA. This injectable gel is designed to promote skin healing, repair. Unlike traditional dermal fillers, which add volume, Rejuran works by stimulating the skin's natural regenerative processes to enhance skin appearance and texture over time, making it an ideal choice for long-term skin health and rejuvenation.

Rejuran is administered by trained medical professionals to treat various skin concerns, such as fine lines, dullness, and under-eye issues by stimulating the skin's natural healing process.

How Rejuran Works

The active ingredient in Rejuran, polynucleotide (PN), is a long-chain DNA fragment extracted and purified from salmon, chosen for its high biocompatibility with human skin. When injected into the dermis, it has the ability to trigger several biological functions including:

  • Cell Regeneration - The polynucleotides signal theskin's fibroblasts (the cells responsible for producing collagen and elastin) toincrease their activity, improving the skin's health from within.
  • Collagen Production - By activating fibroblasts,Rejuran triggers the skin to create its own collagen, which can improve skinfirmness and elasticity.
  • Wound Healing - Rejuran can accelerate the naturalskin healing process while offering anti-inflammatory properties that calmirritated skin and reduce redness.
  • Hydration – Rejuran helps strengthen the skin'sbarrier and can improve its moisture-retention capabilities.

Key Benefits Of Rejuran

What are the main benefits of choosing Rejuran when looking for improvements in your skin's appearance?

  • Stimulates The Skin’s Natural Healing Response - Rejuran works to boost the skin's natural production of collagen and otheressential skin components, promoting a more gradual approach to cell growth andrepair.
  • Minimal Downtime – Mild swelling and redness arepossible side effects (more on this below), but these usually subside relativelyquickly, allowing for minimal disruption to your normal daily routine.
  • More Natural-Looking Results - Since Rejuran works bytriggering your skin's own regenerative capabilities, the improvements are moresubtle, appearing naturally over time.
  • Long-Lasting - A full course of treatments canprovide lasting improvements for 6 to 12 months (maintenance sessions areavailable to prolong the results).

Common Uses

Different formulations of Rejuran are able to address a range of specific skin issues, here is a summary of some of the things Rejuran can be helpful with.

  • Fine Lines And Wrinkles - The boost in collagen andimproved hydration can help soften fine lines, especially around the eyes, mouth, and forehead.
  • Acne And Scaring - A specially formulated thicker Rejuran formula can effectively fill and smooth depressed acne and even surgical scars by promoting maximum tissue regeneration.
  • Under-Eye Concerns - Rejuran can be used for the delicate skin under the eyes to address fine lines, dark circles, and puffiness.
  • UV Damage - Rejuran can help with revitalising skin damage caused by sun exposure and other environmental factors.
  • Common Skin Concerns – Rejuran can be used to address uneven skin tone and texture, redness and enlarged pores.

What To Expect – How Many Treatments Are Needed?

A medical professional administers the Rejuran treatments through a series of micro-injections into the skin. A numbing cream is commonly used to minimise discomfort throughout the procedure. Mild side effects can be expected, such as small bumps, redness, and slight swelling at the injection sites, along with some sensitivity to touch, but these typically resolve within 24 to 48 hours.

A course of three to four initial sessions, spaced about 3 to 4 weeks apart, is the recommended treatment plan. Maintenance treatments are suggested every 6 to 12 months (typically dependent on the age of the patient). Patients often notice improvements in hydration and texture within a few weeks; however, individual results will vary. Optimal results appear gradually over several months as the skin regenerates and repairs itself.

Special recovery instructions to note:

  • Avoid direct sun exposure for at least 48 hours
  • No hot baths, saunas or intense exercise for the first 24hours
  • Refrain from alcohol consumption for 24 hours (reduces risk of bruising)
  • Avoid the use of exfoliants or retinoids for 3 days

What Are The Possible Side Effects?

Rejuran is considered safe and is generally well-tolerated due to its high biocompatibility with human tissue, however as with any cosmetic treatment there are some common and less common side effects. It is important to note you should always seek Rejuran treatment from a qualified practitioner and be sure to consult with your GP if you have any health compatibility or ongoing concerns.

Common Side Effects
  • Small injection bumps
  • Mild redness at the injection sites
  • Slight swelling, particularly in thinner-skinned areas
  • Temporary sensitivity to touch
Less Common Effects
  • Visible bruising at the injection sites
  • Prolonged redness (for more than three days)
  • Itching sensation during the healing phase
Rare Complications (less than 1% of patients)
  • Infection
  • Allergic reaction (allergies to fish can be a concern)
  • Prolonged swelling or nodules

What Is The Difference Between Rejuran And Dermal Fillers?

The key difference between these two cosmetic treatments is that Rejuran’s active ingredient is ‘polynucleotides’, while most dermal fillers use ‘hyaluronic acid’. These two active ingredients both work in different ways to generate very different results when injected into the skin.

Because Rejuran targets the deeper dermal layers for cellular repair, while dermal fillers are used for volume replacement in specific areas, Rejuran provides more gradual, naturally derived changes over time. Whereas dermal fillers offer immediate, visible volume and sculpting.

So to sum up, Rejuran is designed for improving skin quality and enhancement (collagen production and repair), while dermal fillers are primarily for volume enhancement (filling and contouring).
