Profhilo vs Polynucleotides: Which Skin-Boosting Treatment Is Right for You?

At MediZen, two of the most requested skin-quality treatments are Profhilo and polynucleotides. However, both are injectable skin boosters, and both improve the skin from within rather than adding volume or freezing movement. Because they sound similar and are often mentioned together, patients frequently ask us which one is right for them. However, here, MediZen explains profhilo vs polynucleotides in clear, practical terms.

In addition, the honest answer is that it depends on your skin, your age and what you want to achieve. As a result, Profhilo and polynucleotides do different jobs, and for many patients the most effective plan uses both. For example, this guide explains how each treatment works, what results to expect, what they cost and how to choose between them.

What Are Skin Boosters?

Importantly, skin boosters are injectable treatments that improve the quality, hydration and resilience of the skin. Also, unlike dermal fillers, they are not used to reshape the face or add structure. Instead, they work beneath the surface to stimulate your own collagen and elastin. In addition, leaving skin looking smoother, firmer and more radiant over time.

That said, this makes them an excellent foundation treatment for almost any skin. As a result, whether you are in your twenties and focused on prevention or in your fifties and wanting to regenerate tired skin. What is more, Profhilo and polynucleotides are two of the most advanced skin boosters available today. On top of this, they achieve their results in very different ways.

What Is Profhilo?

Of course, Profhilo is a bio-remodelling treatment made from one of the highest concentrations of hyaluronic acid available in an injectable. In short, hyaluronic acid is a substance found naturally in the skin that attracts and holds water, keeping skin plump and hydrated. Crucially, rather than staying in one spot like a filler. For example, Profhilo spreads through the tissue to deeply hydrate the skin and stimulate the production of collagen and elastin.

It is injected at a small number of precise points so that it disperses evenly across the treatment area. Then, this is why it can lift and firm the skin without creating volume in any one place. Likewise, here is what you can expect from Profhilo:

• In fact, how it works: hyaluronic acid is released slowly across the treatment area, remodelling the skin and boosting hydration from within.
• Above all, results: improved hydration, firmness and glow, with a subtle tightening effect that builds gradually over several weeks.
• However, sessions: usually two sessions spaced four weeks apart, followed by maintenance roughly every six months.
• Downtime: minimal. In addition, small raised bumps appear at the injection points and typically settle within a few hours to a day.
• As a result, best for: skin that looks dehydrated, dull or has started to lose firmness. Commonly in patients from their 30s through to their 50s and beyond.

What Are Polynucleotides?

Polynucleotides are a regenerative treatment made from purified DNA fragments. They work at a deeper, cellular level to repair and regenerate the skin, calm inflammation and improve elasticity. Where Profhilo focuses on hydration and remodelling, polynucleotides focus on repair and regeneration. This makes them especially useful for thin, delicate or tired-looking skin.

Because of this regenerative action, polynucleotides are particularly well suited to areas that other treatments struggle to reach safely. Here is what they offer:

• How it works: the treatment stimulates the cells responsible for collagen. Improves skin-cell turnover and acts as an antioxidant to support repair.
• Results: improved texture, elasticity and tone, with a noticeable improvement in skin that looks thin, crepey or fatigued.
• Sessions: typically a course of two to three sessions, spaced two to four weeks apart, with maintenance afterwards.
• Downtime: minimal, with any minor swelling or redness settling quickly.
• Best for: thin, crepey or tired skin, the delicate under-eye area, and anyone wanting deeper regenerative repair.

Why Polynucleotides Excel Under the Eyes

One of the most popular uses of polynucleotides is the under-eye area. The skin here is the thinnest on the body, so it shows tiredness, dark circles and fine lines early. Polynucleotides regenerate and gradually thicken this delicate skin. Improving the appearance of dark circles and crepey texture where stronger treatments would be unsuitable. For many patients, this is the deciding factor in choosing polynucleotides over Profhilo.

Profhilo vs Polynucleotides: The Key Differences

Feature	Profhilo	Polynucleotides
Main ingredient	Hyaluronic acid	Purified DNA polynucleotides
Primary action	Deep hydration and bio-remodelling	Cellular repair and regeneration
Best for	Hydration, firmness, overall glow	Skin repair, elasticity, the under-eye area
Typical course	2 sessions, 4 weeks apart	2–3 sessions, 2–4 weeks apart
Results appear	4–8 weeks	4–8 weeks, building over the course
Maintenance	Around every 6 months	Every 6–12 months
Downtime	Minimal	Minimal

Which Treatment Should You Choose?

Both treatments improve skin quality, but they suit different concerns. As a simple guide:

• Choose Profhilo if your main concern is hydration, dullness or early loss of firmness across the face, neck or hands.
• Choose polynucleotides if you have thin, delicate or crepey skin. Under-eye concerns such as dark circles, or you want deeper regenerative repair.

In practice, the choice is rarely either-or. Profhilo gives an overall lift in hydration and glow, while polynucleotides target repair and the most delicate areas. Many patients see the best results by combining or alternating the two over the course of a year. Addressing both hydration and regeneration. The right approach for you depends on your skin, which is why a proper assessment matters before deciding.

Can You Combine Profhilo and Polynucleotides?

Yes. The two treatments work well together and are often used as part of a longer-term plan. Either combined within the same period or alternated through the year. Your practitioner will advise on the right sequence and timing so that each treatment has the chance to work. At your consultation, a VISIA skin analysis helps us see beneath the surface and recommend whether one or both will give you the best result.
