Rejuran is a skin rejuvenation treatment developed in South Korea and commercially available since 2014 that uses polynucleotides (PN), which are DNA fragments derived from salmon. These polynucleotides help to repair and regenerate the skin from within, promoting collagen production and improving skin elasticity, texture, and hydration.

Rejuran is suitable for individuals with various skin concerns, including:

• Fine lines and wrinkles
• Dull and dehydrated skin
• Uneven skin tone and texture
• Enlarged pores
• Acne scars
• Loss of skin elasticity
• Dark circles and puffiness under eyes

The treatment may not be suitable for individuals who:

• Have active skin infections or severe acne
• Are pregnant or breastfeeding
• Have a history of severe allergic reactions to polynucleotides
• Have certain medical conditions that affect the skin or immune system

1. Numbing and Preparation: Topical anaesthetic cream is applied for 15 - 20minutes. 
2. Microinjections: The polynucleotides are administered using fine needles in a grid-like pattern across the treatment area.
3. Post-Treatment Care: Application of soothing serums or mask or LED light to calm the skin.

The downtime is minimal. You may experience mild redness, swelling, or small bumps (papules) immediately after the procedure, which typically subside within a few hours to a couple of days.

Results can be seen within a few days to a week after the treatment. The skin will appear more hydrated, plump, and radiant.

2 - 3 treatment sessions 1 month apart are recommended. The results of the treatment can last for several months, typically around 6 to 12 months, depending on individual skin conditions and maintenance.

Before the treatment:

• Avoid using retinoids or exfoliating products for a few days.
• Refrain from consuming alcohol or taking blood-thinning medications to reduce the risk of bruising.

After the treatment:

• Keep the skin clean and moisturised.
• Avoid direct sun exposure and use sunscreen.
• Refrain from strenuous exercise or activities that cause excessive sweating for at least 24 hours.
