Types of Rejuran: Which Works Best For You

By Dr Kelvin Chua
Types of Rejuran

Rejuran is an injectable treatment that was developed, manufactured and popularised in South Korea. You may have heard that Rejuran is great for activating your skin’s regenerative ability, giving you baby-smooth skin and restoring youthfulness. However, the truth is a lot more nuanced than that.

In general, Rejuran improves skin hydration, skin texture, skin elasticity, skin repair, and reduces fine lines and wrinkles. But different types of Rejuran treatment in Singapore can help you address different issues. To find out which works best for your skin condition, read more below.

What is Rejuran Made Of?

What is Rejuran Made of

Rejuran is made up of Polyneucleotides (PN) extracted from salmon DNA. A PN molecule is a biopolymer composed of 13 or more nucleotide monomers covalently bonded in a chain. In the case of Rejuran, the P is taken from salmon DNA fragments.

PN molecules have been proven to improve wound healing and many studies have shown that they stimulate cell growth without any side effects.

PN molecules stimulate a cell called a fibroblast, which helps the formation of connective tissue in the body. In the case of our skin, fibroblasts make collagen proteins and form the structural framework of your skin tissue. Rejuran injections can therefore improve the health of your skin.

However, given that there are multiple types of Rejuran, you might be confused about deciding which one is best for you. Let’s break down all the different types of Rejuran you can use.

Rejuran Healer  

The original skin healing treatment that has surged in popularity these few years, Rejuran Healer is often referred to as the “miracle healer injection”. Made popular in China and South Korea, Rejuran Healer is an anti-ageing, skin rejuvenation and skin healing treatment that regenerates skin cells from deep within.

The skin products that came before Rejuran did not use the famed PN active ingredient and could not achieve the same result as Rejuran.

Rejuran Healer has medium viscosity, compared to the other variants we will see below, and is for general application across the face and neck. Using Rejuran Healer treatment in Singapore, you can improve the overall elasticity and tonicity of your skin.

Rejuran HB

The HB in the name stands for “hydration booster”, which refers to the other active ingredient found in this product, Hyaluronic Acid (HA).

While PN stimulates fibroblast growth and collagen stimulation, HA focuses on hydration and lubrication of the body. HA acts as a cushion and lubricant in tissue and is excellent at retaining water. Think of HA like a sponge that can take up many times its weight in water.

In addition to its water-binding capacity, HA has also been found to act as an osmotic pump, delivering water-soluble active ingredients deep into the skin.

Reactions or serious side effects from HA are rare.

While naturally occurring, HA production declines as you age. So Rejuran HB can help to maintain the health of your skin by combining the healing power of PN with the hydrating ability of HA.

Rejuran HB is also good for treating skin damage caused by excessive exposure to UV rays or inappropriate cosmetic treatments.

Rejuran I

What is Rejuran Made of

While HB focuses on whole face hydration boosting, Rejuran I takes care of a more specific problem. Its name sake ‘I’ actually refers to the eye, so what it focuses on is anti-aging specially focused on rejuvenating the eye area.

As we age, we lose collagen and elastin in our skin, with collagen production declining 1-3% every year after the age of 25. The area around the eyes is thinner than the rest of the body, so wrinkles and fine lines around the eye form faster. The loss of collagen also makes the appearance of dark eye circles more obvious.

Rejuran I treatment in Singapore benefits the user by helping to reduce crow’s feet, and improving the appearance of fine lines and increasing elasticity around the eye area, where the skin is usually thin.

While Rejuran I is made up of the same PN substance that is found in the rest of the Rejuran line, Rejuran I is different because it is less viscous than the rest of the products. It is because of this more liquid consistency that Rejuran I is generally safe for use on the delicate skin surrounding the eye.

Rejuran S

Rejuran S, as indicated by the “S” in its name, is formulated to deal with scars. Rejuran S is the more concentrated version of the basic Rejuran product and its anti-inflammatory effects make it good for treating acne scars.

While Rejuran I is thinner, Rejuran S is more concentrated and viscous . This high viscosity promotes tissue restoration and reconstruction, and helps to plump up the skin, reducing the appearance of any depression on the skin. Hence, Rejuran S’s use in treating acne scars.

Acne scars are often caused by inflammation and cystic formation. The body’s natural reaction is to heal itself by secreting collagen to replace the parts that were damaged by the infection. However, in many cases, healing is not optimal. Twisted bands are formed between the skin, and the skin can even sink in to form a depressed mark on the face.

Rejuran S helps improve scars through the induction of collagen production and the healing of the skin. Additionally, Rejuran S is thicker and more gel-like, meaning it can act like a filler to puff up the depressed marks and scars on the face. It can also help to repair the skin at the lower layers.

Overall, most scars will look more shallow and less obvious with the use of Rejuran S. Your doctor may recommend combining Rejuran S with other treatments like fractional lasers to further reduce the appearance of acne scars.

Rejuran S

Which is Best For Me?

The Rejuran of choice would depend on what issue you are facing and how you want to deal with it.

Rejuran Healer is good for those who are looking for a general anti-aging solution because it can be used across the entire face and neck to deliver overall skin rejuvenation. Anyone looking to tighten saggy skin, reduce wrinkles, minimise pore size and improve overall skin tone and skin health can benefit from Rejuran Healer.

Rejuran I has a more specific use; it is more suitable for people looking to rejuvenate the delicate under-eye area. It is also gentle enough for use on the periorbital area. The lighter viscosity of Rejuran I treatment in Singapore makes it a good treatment for crow’s feet, fine lines and dark eye circles.

If you are experiencing acne marks, surgical or trauma scars and blemishes, Rejuran S might be best. Rejuran S has a higher viscosity compared to Rejuran Healer, so it is good for depressed acne scars. Doctors can introduce Rejuran S using a cannula to plump up deep, linear scars. Combined with its regeneration ability, Rejuran S stimulates fibroblasts to produce collagen. For those seeking skin smoothening, shallowing up of acne scar depressions and better skin texture, Rejuran S can be useful.

If you are looking to deliver intense hydration and repair dehydrated areas of your face, then you can consider Rejuran HB. The dual PN and HA ingredients come together to deliver regeneration and hydration to your skin for rapid healing.

Do note that there are plenty of fake Rejuran products outside and using them may create more problems for your skin. You should always consult a trained medical professional to determine what product you need and for them to administer for you.. Never inject Rejuran on your own or buy Rejuran injectables from dubious online sources.
