Polynucleotide Skin Booster vs Bio-Remodelling: Which Suits Your Skin?

The short answer

Polynucleotide skin booster works on the biological repair side of skin quality. Bio-remodeller works on the structural support side. Both improve skin quality, but they reach that outcome through different mechanisms, and most doctors will recommend one over the other based on what specifically is wrong with your skin.

What each one actually is

Polynucleotide (PN) skin booster

The active ingredient is purified polynucleotides — long chains of DNA fragments, originally derived from salmon. These molecules have demonstrated biological activity in stimulating fibroblast function, promoting collagen synthesis, and supporting cellular repair. The treatment was developed and popularised in Korea, where it remains a clinic-staple.

When injected intradermally at multiple micro-points across the face, the polynucleotides support the skin’s own regeneration process. Over a 4 to 8 week period after each session, patients typically notice improvement in texture, fine lines, and the “healed-ness” of the skin — especially in skin that has been damaged by sun, acne, or general ageing.

Bio-remodelling booster

The active ingredient is a stabilised, BDDE-free form of hyaluronic acid that combines two molecular weights of HA in a single product. Where standard HA fillers are designed to add volume in a specific area, bio-remodeller is designed to spread through the dermis after injection — hydrating the tissue and stimulating both collagen and elastin production.

Bio-remodeller is administered at 5 to 10 specific anatomical points (called Bio Aesthetic Points or BAP) per side of the face. Over the following weeks, the HA disperses across the dermis, and the bio-remodelling effect kicks in.

Side-by-side comparison

Active ingredient: Polynucleotide – DNA fragments | Bio-remodeller (bio-remodelling booster) – Stabilised hyaluronic acid (dual MW)

Primary mechanism: Polynucleotide – Stimulates cellular repair | Bio-remodeller – Bio-remodelling, collagen + elastin

Best for: Polynucleotide – Skin texture, post-acne marks, fine lines, dull skin | Bio-remodeller – Skin laxity, crepey texture, deep hydration

Injection technique: Polynucleotide – Many micropoints across face | Bio-remodeller – 5 to 10 BAP points per side

Sessions: Polynucleotide – Typically 3 sessions, 3 to 4 weeks apart | Bio-remodeller – Typically 2 sessions, 4 weeks apart

Maintenance: Polynucleotide – Every 6 months | Bio-remodeller – Every 6 months

Downtime: Polynucleotide – Mild bumps 24 to 48 hours | Bio-remodeller – Mild bumps 24 to 48 hours

Which one is right for you?

The honest answer is that this is the question your doctor is best placed to answer after assessing your skin. But here’s how we typically think about it at IVI:

• Skin laxity is your dominant concern: bio-remodeller is usually the better lead. The dual-MW HA spreads across the dermis and addresses the structural component of skin quality.
• Texture, post-acne marks, or “tired” skin: polynucleotide skin booster is usually the better lead. It supports cellular repair and is particularly useful for skin that has been damaged by sun, inflammation, or repeated trauma.
• You want overall skin quality improvement and aren’t sure which problem is dominant: a combination protocol is common — one of each, spaced 2 to 4 weeks apart, with maintenance alternating.
• You want volume restoration: neither product is the right answer. You’re looking for traditional HA filler or a collagen-stimulating injection like a PLLA biostimulator.

What about cost?

Pricing varies by clinic and protocol, and Singapore healthcare advertising rules limit how we can discuss it publicly. What we can say: both treatments are positioned in a similar price band, and the total cost is influenced more by the number of sessions in your plan than by the choice between products.
