The under-eye area is one of the first places to show tiredness, fine lines and a thin, crepey texture — and it's also one of the trickiest to treat well. Polynucleotides have become a popular option here because they work with your skin rather than simply filling it. Here's an honest look at what they can and can't do.

What are polynucleotides?

Polynucleotides are injectable regenerative treatments made from purified, fragmented DNA chains (most commonly derived from highly purified salmon or trout sources). Rather than adding volume, they act as a "bio-stimulator": they hydrate the skin from within, support the fibroblast cells that produce collagen and elastin, and help calm inflammation. Over time, that tends to show up as smoother, more resilient, better-quality skin.

Do they work for under-eyes?

For the right person, yes — polynucleotides can make a genuine difference to the under-eye area. They're particularly useful for:

  • Crepey, thin skin and fine "smile lines" under the eyes
  • Dark circles caused by thin, poor-quality skin (rather than by shadow from hollowing)
  • A tired, dull appearance where the skin needs hydration and support

Most people notice the area looks fresher and smoother as results build over the weeks following a short course.

What they can't do

This is where honest expectation-setting matters. Polynucleotides are not a dermal filler. If your main concern is a hollow tear trough or volume loss, that's a different problem and polynucleotides won't "fill" it. Equally, dark circles caused by pigmentation or genetics may only partially improve. At your consultation we'll be straight with you about whether this is the right tool for your particular under-eyes — and if it isn't, we'll say so.

What to expect from treatment

Under-eye polynucleotide treatment is quick, but the area is delicate, so it should always be carried out by an experienced practitioner. Typically:

  • A short course of 2–3 sessions, spaced around 2–4 weeks apart, tends to give the best results
  • Results build gradually over the following weeks as the skin responds
  • Downtime is usually minimal, though small bumps, mild swelling or occasional bruising can occur and settle quickly
  • Many people choose a maintenance session every 6–12 months to keep results topped up

Is it right for you?

The under-eye area rewards a careful, individual approach — what works beautifully for one person isn't right for another. The best next step is a proper assessment. We offer polynucleotide treatments as part of a wider range of under-eye and tear-trough options, so we can recommend the approach that genuinely suits your skin rather than a one-size-fits-all fix.
