Polynucleotides vs Profhilo: Which Skin Booster Is Right for You?

Two of the most frequently searched injectable skin treatments in the UK right now are polynucleotides and Profhilo. Both have earned genuine enthusiasm from practitioners and clients because both deliver real improvements to skin quality. But they work differently, suit different clients, and often produce different results. If you are trying to decide between them — or wondering whether you need one, both, or neither — this guide will give you an honest answer.

This post is part of our guide to our polynucleotide treatment page at DZ Beauty, Sutton Coldfield.

What Are Polynucleotides?

Polynucleotides — often called PDRN (polydeoxyribonucleotide) — are fragments of purified DNA extracted from salmon or trout. When injected into the skin, they bind to cellular receptors and trigger a repair and regeneration response. The skin's fibroblasts produce more collagen and elastin. Oxidative stress is reduced. Tissue repair is accelerated.

The result is a gradual improvement in skin quality — texture, tone, firmness, and luminosity — that builds over a course of three sessions. Polynucleotides do not add volume and do not change the structural appearance of the face. They make your skin healthier. They are particularly effective for under-eye crepiness, post-acne skin, sun-damaged skin, and early-stage laxity.

What Is Profhilo?

Profhilo is an injectable treatment using the highest concentration of pure hyaluronic acid available in any product on the market. Unlike a traditional filler, it does not contain added crosslinkers. Instead, it spreads through the tissue and bio-remodels from within — stimulating collagen types I and III, elastin, and hyaluronic acid production simultaneously. It also provides intense hydration at a depth that topical products cannot reach.

The result is a plumper, more hydrated, more elastic skin with improved tone and reduced laxity. Most clients need two sessions one month apart. The effect is visible quite quickly — often within three to four weeks of the first session. Profhilo is particularly well-suited to clients with dry or dehydrated skin, visible laxity, or loss of skin elasticity.

The Key Differences

• Mechanism: PDRN triggers cellular repair and regeneration. Profhilo deeply hydrates and bio-remodels via hyaluronic acid.
• Results timeline: Both build over weeks, but Profhilo tends to show hydration improvements faster. Polynucleotides build texture and quality more gradually.
• Ideal candidate: Polynucleotides suit skin quality concerns, under-eye crepiness, scarring, and prevention. Profhilo suits dryness, laxity, and clients wanting a "plumper skin" effect.
• Sessions: Profhilo — 2 sessions 1 month apart, then 6-monthly. Polynucleotides — 3 sessions 2–4 weeks apart, then 3–6 monthly.
• Injection technique: Profhilo is injected at 5 specific "BAP" (Bio Aesthetic Points) per side. Polynucleotides are injected with a finer mesotherapy technique across the treatment area.
• Can be combined: Yes — many clients benefit from both, targeting different aspects of skin health.

Who Is Each Best For?

Choose polynucleotides if your primary concerns are: fine lines and crepey texture, post-acne or sun-damaged skin, under-eye hollows and crepiness, early-stage skin laxity, or long-term skin quality investment. Polynucleotides are also the stronger choice for cellular repair and are recommended by many practitioners for clients in their 30s investing in prevention.

Choose Profhilo if your primary concerns are: dry, dehydrated skin that lacks plumpness, visible skin laxity (neck, face, arms, hands), lack of elasticity and bounce, or you want visible hydration and renewal relatively quickly. Profhilo is also popular as a "prejuvenation" treatment for clients in their mid-30s to 40s.

What We Typically Recommend at DZ Beauty

At our Sutton Coldfield clinic, we find that many clients benefit from a combination of both treatments — particularly those in their late 30s and 40s who have both skin quality decline and early laxity. We typically recommend starting with a course of polynucleotides if the primary concern is skin texture, radiance, or under-eye concerns. If the primary concern is hydration and laxity, Profhilo is often the better starting point.

We never recommend more treatment than a client genuinely needs. If polynucleotides alone will address your concern effectively, we will say so. If a combination approach is genuinely beneficial, we will explain why and let you decide. The consultation is the honest conversation — not a sales pitch.
