What is Rejuran?

First and foremost, we need to understand what exactly is Rejuran. It is an injectable treatment that consists of polynucleotides (PN), or polydeoxyribonucleotide (PRDN), and these molecules form long chains that are known as DNA. Specifically, these DNA are obtained from salmon. Simply put, it is made of salmon DNA.

I know what you are thinking. Salmon DNA? Don’t worry as the salmon DNA has been purified and processed thoroughly for medical aesthetic purposes, making it safe, stable and biocompatible with human skin. Scientists have proven that Salmon DNA is able to accelerate the repair and regeneration process of our skin cells, leaving us with a rejuvenated, firmer skin. It is also beneficial in achieving a well-hydrated skin. Overall, Rejuran promotes tissue regeneration, wound healing and skin repair to help with full face rejuvenation.

What are the different types of Rejuran?

Many people are often confused with the different types of Rejuran. There is a range of products with different purposes. Here is a brief summary of each of them .

What are the differences between the Rejuran products?

Rejuran Healer

Rejuran Healer is used for full face rejuvenation and skin healing. It can be applied on all areas of the face to help your skin revitalize and moisturize.

Rejuran S

Rejuran Scar typically helps with scar removal by repairing damaged tissues. People with acne scars often use it to improve the healing process of their scars. Compared to Rejuran Healer, it is thicker, so it can be safely injected  scarred areas that have denser tissues and skin. The amount of Rejuran Scar needed depends on the areas of scars treated.  You can usually see the effects after 3-4 sessions at 1-month intervals.

Rejuran I

Rejuran i helps with fine wrinkles around the eyes and could also be used to improve the appearance of dark eye circles. Compared to Rejuran Healer, you can easily injected it into the areas around your eyes which are more sensitive and have thinner skin. You can usually see the effects after 3-4 sessions at 1-month intervals.

Rejuran VS Skin Booster

Skin boosters are filler treatments which involve micro-injections of hyaluronic acid into our skin to restore the moisture. It mainly helps to improve hydration in our skin. However, Rejuran acts on a cellular level. Instead of directly injecting our skin with important components such as hyaluronic acid, it stimulates the skin to produce these components itself, rejuvenating the skin from within. It focuses on skin repair and regeneration.

Anyone who is looking to slow down the signs of skin aging or heal severely damaged skin can consider Rejuran. This includes:

  • Aging and loose skin
  • Fine lines and wrinkles

  • Improving skin texture
  • Reducing enlarged pores and fine wrinkles
  • Improving skin elasticity for firmer, lifted skin
  • Hydrating and moisturizing dry skin
  • Balancing the sebum and hydration levels of our skin
  • Reduce dark spots on face caused by scarring

How long does Rejuran last?

The effect typically last between 6-12 months. We reccommend you to go for 3-4 sessions at 3-4 weeks interval, followed by one every 6 months for maintenance. You will start to see clear results 2-3 weeks after the first treatment. Results seen may vary depending on the skin condition and lifestyle.

How is the procedure like?

Is Rejuran painful? Clinicians will apply numbing cream to the targeted areas for about 45 minutes before injection. This will help to minimize any discomfort or pain.

Clinicians will then manually inject Rejuran into the skin with a very small needle. We normally use manual injections as it more effective with minimal downtime and pain. This process will take about 20-40 minutes depending on the size of the targeted areas. You will go through LED light therapy to maximise results. This will take about 15 minutes.

What are the side effects?

Most people are concerned about whether is Rejuran safe. While there may be short-term side effects that will recover within days, there are no proven long-tern side effects.


Clinicians will inject using small needles in multiple dots, thus, it will create bumps that look like mosquito bites all over the face. However, do not worry as these will only take 12-24 hours to disappear.

Redness and swelling

Some people may experience mild redness and swelling after the treatment due to the injection of needles. However, these will resolve in 24-28 hours. There is minimal downtime, you can resume your daily activities as soon as the treatment is over.

Here are some tips to maximize results!


Skin lightening treatments can further reduce melanin or pigmentation in our skin cells. Addition of clinical light and laser energy targeted at melanin remove stubborn pigmentation such as sunspots, freckles, and even melasma quickly.


Hyaluronic acid found in hydrating products can further moisturize the internal cell matrix of the skin. We recommend you to moisturise over 3 to 4 times weekly to achieve deeper internal skin hydration.

Acne Clear

Skin laser and peel can reduce the sebum production of overactive skin type. We recommend you to do it as a monthly therapy to achieve blemish-free skin.
