Rejuran and Plinest are both regenerative skin booster treatments that use polynucleotides, also known as PN, to support skin repair, collagen activity and overall skin quality.
Although they are often grouped under the same “PN skin booster” category, they are not exactly the same. Rejuran is often more repair-focused, while Plinest is commonly chosen for skin rejuvenation, hydration, elasticity and healthy ageing support.
The right choice depends on your skin condition, skin goals, lifestyle and treatment expectations.
Polynucleotide skin boosters are injectable treatments designed to improve skin quality from within.
Unlike dermal fillers, PN skin boosters are not mainly used to reshape the face or add obvious volume. Instead, they support the skin’s repair and rejuvenation process over time.
Depending on the treatment selected, PN skin boosters may help improve:
For patients comparing regenerative skin treatments, PDRN treatment may also be relevant during consultation.
Rejuran is a Korean polynucleotide treatment commonly associated with salmon DNA-derived PN technology. It is widely known for its skin repair and regeneration-focused approach.
Rejuran contains approximately 2% PN and uses high molecular weight polynucleotides. It has a thicker gel consistency and is often considered for patients who want deeper skin recovery and collagen remodelling support.
Rejuran is commonly used for concerns such as acne scars, enlarged pores, damaged skin barrier and rough skin texture.
For patients interested in Rejuran around the eye area, Rejuran-I treatment may be considered after a doctor’s assessment.
Rejuran may help support:
Rejuran tends to work more like a regenerative skin repair treatment rather than a glow-focused skin booster. It may be more suitable for patients whose main concerns are skin damage, rough texture, pores or mild acne scarring.
For patients with pores, acne marks or uneven texture, open pore and acne scar treatments may help identify whether Rejuran, laser, subcision or other skin treatments are more appropriate.
Plinest is an Italian polynucleotide injectable developed with PN-HPT® purification technology. It is designed to support skin rejuvenation, hydration, elasticity and tissue regeneration.
Plinest contains approximately 20mg/ml, or 2%, PN. Compared with Rejuran, Plinest is often described as having a lighter and smoother consistency.
It is commonly chosen for patients who want overall skin quality improvement, softer-looking skin, healthy ageing support and natural skin rejuvenation.
For patients considering Plinest directly, Plinest treatment may be suitable depending on the skin assessment.
Plinest may help support:
Plinest is often preferred by patients who want skin that looks more hydrated, refreshed and naturally rejuvenated.
For patients mainly concerned with dullness, dryness or sensitivity, dry and sensitive skin treatment may help determine whether Plinest, hydration boosters or barrier repair treatments are more suitable.
| Comparison Area | Rejuran | Plinest |
|---|---|---|
| Origin | Korean PN treatment | Italian PN treatment |
| Main Focus | Skin repair and regeneration | Hydration, elasticity and tissue rejuvenation |
| PN Concentration | Approximately 2% PN | Approximately 20mg/ml, or 2% PN |
| Texture | Thicker gel consistency | Lighter and smoother consistency |
| Best For | Acne scars, pores, damaged skin barrier and rough texture | Dullness, dehydration, elasticity and overall skin quality |
| Result Direction | More repair-focused | More rejuvenation-focused |
| Ideal Patient | Patients with damaged, textured or weakened skin | Patients with dull, dehydrated or ageing skin |
Rejuran may be more suitable if your skin needs deeper repair and regeneration support.
You may consider Rejuran if your concerns include:
Rejuran is usually a better match for patients who want to improve skin damage, texture and repair-focused concerns rather than mainly hydration or glow.
If fine lines and skin ageing are also a concern, fine lines and wrinkle treatment assessment may help determine whether Rejuran, Plinest, Botox, skin boosters or combination treatments are more suitable.
Plinest may be more suitable if your goal is hydration, elasticity, radiance and overall skin quality improvement.
You may consider Plinest if your concerns include:
Plinest is often preferred by patients who want their skin to look smoother, healthier and naturally refreshed.
For patients mainly focused on hydration, glow and elasticity, Profhilo treatment may also be discussed as another skin booster option.
For acne scars, enlarged pores and rough texture, Rejuran is often the more repair-focused option.
However, acne scars and pores can have different causes and depths. Some patients may need combination treatment with laser, subcision, microneedling or collagen-stimulating procedures.
For deeper acne scars, subcision treatment or CO2 laser treatment may be considered after a proper skin assessment.
For hydration, radiance and smoother-looking skin, Plinest may be more suitable because it is commonly positioned around skin rejuvenation, elasticity and tissue quality.
However, glow-focused results depend on more than one treatment. Skin condition, skincare routine, sleep, sun exposure, hydration and treatment consistency can all affect the final result.
A personalised consultation helps determine whether Plinest, Profhilo, PDRN or another skin booster would better match your skin goals.
In some cases, different regenerative treatments may be combined or staged as part of a customised skin rejuvenation plan.
For example, one patient may need Rejuran for texture and repair, while another may benefit more from Plinest for hydration and elasticity. Some patients may require a treatment plan that addresses both repair and rejuvenation over time.
Combination treatment should always be planned carefully based on skin condition, sensitivity, downtime tolerance and treatment goals.
There is no single best choice for everyone.
In simple terms:
Rejuran may be more suitable for damaged, textured or weakened skin. Plinest may be more suitable for dull, dehydrated or ageing skin that needs hydration, elasticity and overall quality improvement.
The best option depends on what your skin actually needs.
Before choosing Rejuran or Plinest, a doctor consultation is important because skin concerns often overlap.
For example, dull skin may be caused by dehydration, pigmentation, poor skin barrier, ageing or lifestyle factors. Enlarged pores may be related to oil production, collagen loss, acne scarring or skin laxity.
During consultation, the doctor can assess:
This helps ensure the selected treatment is suitable, realistic and aligned with your skin condition.
Rejuran and Plinest are both regenerative PN skin boosters, but they serve slightly different skin goals.
Rejuran is generally more suitable for repair-focused concerns such as acne scars, pores, damaged skin barrier and rough texture. Plinest is more suitable for skin rejuvenation, hydration, elasticity and healthy ageing support.
Instead of choosing based on trend or popularity, the best approach is to assess your skin condition and match the treatment to your actual skin needs.
