Polynucleotides vs Profhilo: What's the Difference and Which Treatment Is Best?
Profhilo vs polynucleotides
“Which one should I actually have?” It’s one of the most common questions I hear at consultation once patients have done their own research into skin boosters. Profhilo and polynucleotides both promise the same broad outcome: healthier, better quality skin without looking overdone, but they get there in genuinely different ways. Knowing which one matches your skin is the difference between a treatment that meets your expectations and one that just leaves you out of pocket and mildly disappointed.
I get asked this often enough that I wanted to set out, plainly, what separates Profhilo vs Polynucleotides, two of the skin boosters I offer most often, and how I actually decide which to recommend when a patient sits down in front of me. As a GP as well as an aesthetics doctor, working from a CQC-regulated clinic, I look at that decision clinically first and cosmetically second.
What’s actually different between the two treatments
Profhilo is a hyaluronic acid treatment. It isn’t a filler in the traditional sense; it doesn’t add volume, but it carries a very high concentration of hyaluronic acid that spreads through the tissue after injection, pulling in moisture and encouraging your own collagen and elastin to get back to work. Think of Profhilo as a hydration reset for skin that has started to look tired rather than lined.
Polynucleotides work differently. They’re derived from purified DNA fragments, and rather than hydrating from the outside in, they act more like a repair signal, prompting the fibroblast cells in your skin to regenerate tissue that has been affected by sun exposure, scarring, or simply time. A polynucleotide skin booster is doing something closer to structural repair than surface refreshment, which you can read more about on our Polynucleotide Treatment page.
Neither is “stronger” than the other. They’re built for different jobs, which is really the whole point of comparing them at all.
If you’d like the full clinical picture, including the research behind how polynucleotides work, I’ve written a longer piece on that here: our full guide to polynucleotides.
Which one suits your skin concern
If your main complaint is that your skin looks dull, dehydrated or a little crepey, particularly around the cheeks or lower face, Profhilo tends to be my first suggestion. Patients often describe the result as looking like they’ve finally had a good night’s sleep.
If you’re dealing with something more structural, acne scarring, sun damage, or thinning skin that’s lost its resilience rather than just its glow, polynucleotides usually make more sense. They work more slowly, but the improvement tends to run deeper than surface hydration.
Plenty of patients don’t fit neatly into either camp, and that’s completely normal. Skin rarely respects tidy categories, which is exactly why I never recommend either treatment without seeing your skin in person first.
How soon you’ll notice a change, and how long it lasts
Profhilo tends to show results faster. Most patients notice a visible improvement in hydration and glow within a week or two of the first session, with the full effect settling in after a short course.
Polynucleotides ask for a little more patience. Because they’re working on tissue repair rather than hydration alone, changes build gradually over several weeks, and improvement in texture often continues for a couple of months after your last session. What you lose in speed, you tend to gain in staying power; results from polynucleotides generally hold a little longer between top-ups than Profhilo does.
Can you have both
Yes, and quite often that’s exactly what I recommend. Hydration and repair aren’t competing goals; they’re complementary ones, and I regularly build a plan that sequences the two treatments a few weeks apart depending on what your skin needs first.
Some patients also do well combining either treatment with PRP Facials, which uses your own plasma to support the same regenerative process from another angle. I’ll only suggest adding it in if I think your skin will genuinely benefit, not as a matter of course.
A few more things patients ask me before deciding
Is one better value than the other? Not in a straightforward way. Profhilo often looks cheaper per visit, but polynucleotides tend to hold their result for longer between top-ups, so it’s worth comparing the two over a year rather than one appointment at a time. I’ll talk you through what that looks like for your skin at consultation, with real figures rather than a rule of thumb.
Can I switch if my first treatment doesn’t suit me? Yes. Neither treatment locks you in, and it’s genuinely common for me to adjust a plan after seeing how your skin responds to the first session.
Is either a good starting point if I’ve never had an injectable before? Both are gentler introductions than a traditional filler, since neither changes your facial shape. Which one I’d suggest as a first step still comes down to what your skin is telling me at consultation.
What happens at your consultation
I never recommend a treatment before I’ve actually looked at your skin. At your consultation, we’ll talk through what’s bothering you, I’ll examine your skin’s texture, tone and elasticity, and we’ll agree a plan that fits your goals and your budget, not a package I’m trying to upsell you into. If Profhilo and polynucleotides both have a role to play, I’ll say so and explain why, and if only one does, I’ll tell you that too.
My clinic is based in Jesmond, Newcastle upon Tyne, and every plan I write is built around what your skin specifically needs, not a generic protocol.
Making the decision
There’s no universal winner in the Profhilo vs Polynucleotides debate. The honest answer is that the best skin booster is simply the one that matches the skin in front of me, not a blanket recommendation that suits everybody. If you’re still unsure which applies to you, that’s exactly what a consultation is for.
