In the aesthetic market, the polynucleotide skin booster has become a popular regenerative treatment among dermatologists, and this approach is gaining attention worldwide.
Unlike dermal fillers or traditional skin boosters, polynucleotides (PN) work as bioregulatory molecules that support the skin’s natural repair process. For patients seeking healthier, firmer, and better-hydrated skin, PN offers a regenerative approach to skin rejuvenation.
This guide explains what a polynucleotide skin booster is, how it works, the concerns it may help address, and what clinicians can expect from real-world applications.
A polynucleotide skin booster is an injectable treatment made from highly purified DNA fragments, typically derived from salmon or trout. It is injected into the superficial to mid dermis to help support fibroblast activity and promote collagen and elastin synthesis. As collagen remodeling continues over time, the skin gradually becomes firmer, smoother, and better hydrated without creating an unnatural or overfilled appearance.
Different areas of the body have different requirements for the concentration and formulation of polynucleotide skin boosters. To address these needs, the PNPure™ series was developed with dedicated PN skin booster formulations for the face, periocular area, and other treatment areas.

The main benefits of PN skin booster include:
Improved skin elasticity and firmness: Supports fibroblast activity and collagen remodeling to improve dermal structure.
Reduced appearance of fine lines: Commonly used for concerns such as cheek lines, under-eye lines, and forehead wrinkles.
Improved skin hydration: Helps improve dry and dehydrated skin conditions.
Smoother skin texture: Supports dermal quality and may help reduce the appearance of enlarged pores.
Brighter skin appearance: Helps improve dullness and restore a healthier-looking glow.
Clinical observations show that the effects of PN follow a “cumulative” biological process:
1. Initiation phase (after the first treatment): Fibroblast activity is stimulated, the skin’s natural hydration capacity is enhanced, and skin radiance and translucency are improved.
2. Remodeling phase (after the treatment course): With the organized reconstruction of the extracellular matrix, fine lines are reduced, the skin barrier becomes stronger, and skin resilience and firmness are improved.
3. Maintenance phase: Continuous regeneration of endogenous collagen and elastic fibers helps extend the duration of results, breaking the decline cycle of a single treatment and maintaining a more stable rejuvenated skin condition.
The following examples are based on real clinical observations:
Patient profile: A 44-year-old female with multiple under-eye fine lines and uneven, dull skin tone.
Treatment: PNPure™ NeoEye Skin Booster was used for targeted periocular treatment.
Initial results: Improved appearance of periorbital wrinkles and increased skin brightness. Physician assessment showed overall aesthetic improvement.
Patient profile: A patient with dull skin, pigmentation concerns, mild facial depressions, and reduced tissue support.
Treatment: PNPure™ NeoSkin Skin Booster was used for broader facial skin quality improvement.
6-month follow-up: Improved facial texture, reduced uneven skin tone, and enhanced skin radiance and hydration were observed.
Polynucleotide injections are generally well tolerated when performed by trained medical professionals.
Common temporary reactions include redness, swelling, bruising, and small injection papules. These effects usually resolve within 24–72 hours.
Many patients notice improvements in hydration and skin texture within several weeks, while collagen remodeling continues over the following months.
PN is commonly used for the face, under-eye area, neck, and other areas with concerns related to skin aging and reduced elasticity.
Regeneration begins at the cellular level. Although the clinical applications of the polynucleotide skin booster have achieved many positive outcomes, its full potential has yet to be fully explored. Facing increasingly diverse anti-aging needs, how to maximize its therapeutic value remains a topic worthy of continued exploration by every aesthetic professional.
