Types of Rejuran

Korean PN is an injectable treatment that was developed, manufactured and popularised in South Korea. You may have heard that Korean PN 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, Korean PN improves skin hydration, skin texture, skin elasticity, skin repair, and reduces fine lines and wrinkles. But different types of Korean PN treatment in Singapore can help you address different issues. To find out which works best for your skin condition, read more below.

What is Korean PN Made Of?

What is Rejuran Made of

Korean PN 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 Korean PN, 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. Korean PN injections can therefore improve the health of your skin.

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

Korean PN Healer  

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

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

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

Korean PN 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 PN Restore HB can help to maintain the health of your skin by combining the healing power of PN with the hydrating ability of HA.

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

Korean PN I

What is Rejuran Made of

While HB focuses on whole face hydration boosting, Korean PN 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.

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

Korean PN S

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

While Korean PN I is thinner, Korean PN 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, Korean PN 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.

Korean PN S helps improve scars through the induction of collagen production and the healing of the skin. Additionally, Korean PN 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 Korean PN S. Your doctor may recommend combining Korean PN S with other treatments like fractional lasers to further reduce the appearance of acne scars.

Rejuran S

Which is Best For Me?

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

Korean PN 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 Korean PN Healer.

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

If you are looking to deliver intense hydration and repair dehydrated areas of your face, then you can consider Korean PN 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 Korean PN 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 Korean PN on your own or buy Korean PN injectables from dubious online sources.
