Polynucleotides vs Skinboosters vs Profhilo
The three are often grouped together as “skin quality” injectables, but they work differently and buy you different results — which matters when you’re deciding what to stock.
Polynucleotides are DNA fragments, typically derived from salmon or trout milt. They act on the tissue itself: supporting fibroblast activity, hydration and the skin’s own regenerative processes over a course of treatments. Best suited to thin, crepey or fragile skin — and the only one of the three routinely used in the under-eye area and on the scalp.
Skinboosters are low-viscosity hyaluronic acid injectables. They deliver hydration and a visible glow relatively quickly, working primarily through HA’s water-binding capacity rather than tissue remodelling. Effects are more immediate but generally shorter-lived.
Profhilo is a high-concentration stabilised HA bio-remodeller delivered through a fixed five-point protocol. It’s strongest on laxity and structural support in the lower face and neck, with a shorter treatment course than most PN protocols.
In practice: many clinics stock all three and select by indication — polynucleotides for regeneration and delicate areas, skinboosters for hydration and glow, Profhilo for laxity. They also combine well in sequenced protocols.
Polynucleotides are purified DNA fragments — most commonly PDRN (polydeoxyribonucleotide) extracted from salmon or trout milt, which is highly compatible with human DNA and non-immunogenic once purified. The formulations supplied here are sterile, protein-free and manufactured to medical-device standards.
Once injected into the dermis, polynucleotides act as a biological scaffold. They support fibroblast activity, help the tissue retain water, and assist the skin’s natural repair processes. Unlike a dermal filler, they add no volume — the change comes from improved skin quality: texture, elasticity, density and tone.
Composition. Depending on brand, formulations vary in PN chain length and concentration — from lighter periorbital products through to high-concentration options for laxity. Some products, such as Croma Polyphil, combine polynucleotides with hyaluronic acid for added hydration and immediate support.
Protocol and duration. A typical course is 3–4 sessions spaced 2–4 weeks apart, with maintenance every 6–12 months. Most patients notice progressive improvement across the course rather than an immediate change, with results developing over the weeks following each session. Duration varies by product, area treated, patient age and skin condition — always follow the manufacturer’s IFU for the specific product.
Common treatment areas: mid and lower face, periorbital area, neck, décolleté, hands, and scalp for hair-thinning protocols.
Techniques. Polynucleotides are administered intradermally or into the superficial subdermal plane. The three most-used approaches:
A cannula is often preferred in the periorbital area to reduce bruising risk. Depth, volume per point and needle gauge differ by product — refer to the manufacturer’s protocol for each SKU rather than applying one technique across the range.
Kinami Health supplies products to licensed professionals. Clinical technique remains the responsibility of the treating practitioner.
Polynucleotide treatments are generally well tolerated. The most common reactions are localised and short-lived: redness, swelling, small papules at injection points, tenderness and occasional bruising, typically resolving within a few days.
Less common reactions include prolonged swelling or nodules, usually related to injection depth or volume. As with any injectable, aseptic technique and correct patient selection matter.
Contraindications generally include pregnancy and breastfeeding, active infection or inflammation at the treatment site, autoimmune conditions and known hypersensitivity to fish-derived products. Consult the manufacturer’s IFU for the full contraindication list for each product.
What are polynucleotides used for?
Skin regeneration and quality — texture, elasticity, hydration and density. They’re widely used on the face, neck and décolleté, in the under-eye area, and on the scalp for hair-thinning protocols. They are not volumising products.
Are polynucleotides the same as dermal fillers?
No. Dermal fillers add volume and structure. Polynucleotides work on skin quality by supporting the tissue’s own regenerative processes, without adding volume.
How many sessions are needed?
Typically 3–4 sessions at 2–4 week intervals, then maintenance every 6–12 months. This varies by product and indication.
Are polynucleotides safe?
The formulations we supply are purified, protein-free and manufactured to medical-device standards, and are generally well tolerated. Side effects are usually mild and short-lived. They must be administered by a trained, licensed practitioner.
Can polynucleotides be combined with other treatments?
Yes — they’re commonly sequenced with skinboosters, Profhilo, dermal fillers, botulinum toxin and energy-based devices. Spacing and order should follow each manufacturer’s guidance.
Where can I buy genuine Nucleofill, Plinest and Rejuran?
Kinami Health supplies all three through authorised channels, with batch traceability and manufacturer packaging on every unit. Register a practitioner account to view stock and pricing.
What is the wholesale price for polynucleotides?
Wholesale pricing is tiered by volume and shown once your practitioner account is verified. For bulk or multi-brand orders, request a quote and we’ll price the full basket.
Do you ship internationally?
Yes — tracked, temperature-controlled shipping to licensed practitioners worldwide. Delivery times and any import requirements are confirmed at checkout.
