Choosing between Pullureal and hyaluronic acid injectable: building firmness or instant replenishment?

PN (polynucleotide) injections like Pullureal work to establish the skin's foundation over time, whereas hyaluronic acid injections add moisture and volume on the spot—they serve different roles.[1][2]In a comparative study of the under-eye area, there was no difference in visible improvement, but PN showed better numerical results for skin elasticity and hydration.[3]However, all studies are small-scale and quality varies,[4]and no studies comparing the product Pullureal specifically were found in this review.

PN and PDRN: same DNA component but what is different?

The difference is in the length of DNA fragments. PN consists of longer fragments and is involved in rebuilding the skin's foundation (the tissue around cells).[2]PDRN consists of shorter fragments and is described as working on cell receptors to normalize skin condition.[2]

When fragment length differs, how they work within the skin changes. For this reason, rather than lumping them together as "DNA injections," it becomes easier to compare when you confirm which component is being used.

How is hyaluronic acid injection different?

The major difference is that hyaluronic acid works immediately while PN works gradually.[1]PN gradually refines skin quality over several weeks, while hyaluronic acid immediately supplements shape and volume.[1]

In a 27-person trial where PN and fluid hyaluronic acid were injected on alternate sides of the under-eye area, injection was performed 3 times at two-week intervals.[3]There was no difference in visible improvement, but the rate of improvement in skin elasticity, hydration, skin texture, and pore refinement was higher on the PN side.[3]However, improvement rates on both sides declined over time.[3]

What changes when PN and hyaluronic acid are combined?

The combined approach aims to achieve both the hydration of hyaluronic acid and the foundation-building effect of PN at the same time.[2][5]It has been reported that PN is often used in combination with other ingredients such as hyaluronic acid.[2]

There are also reports of PN and fluid hyaluronic acid being used together in the under-eye area.[6]However, within the scope of this review, no studies were found comparing combination injections with PN-only injections under the same conditions in human skin, so the magnitude of added benefit remains unclear.

Which works best for hollowness under the eyes?

If you want to fill deep hollowness, PN alone is often insufficient. This is because PN is designed to refine skin quality without adding excess volume.[7]

On the other hand, hyaluronic acid fillers used for hollows can reshape immediately, but it has been noted that irregularity and displacement of position can occur under the eyes.[7]In hyaluronic acid injected around the eyes, swelling and bluish discoloration of the skin (Tyndall effect) have also been reported.[1]

Are there differences in how side effects appear?

PN and hyaluronic acid are reported to differ more in how side effects appear than in effectiveness.[1]In a report summarizing 219 people who received PN injections, side effects were generally mild and temporary, with no serious complications.[1]

The most common are redness, flushing, and small bruising.[1]With hyaluronic acid, there are rare reports of the substance entering blood vessels causing skin necrosis (tissue damage and darkening) or blindness, and caution is advised.[8]

How should you choose based on your specific concern?

The guideline is whether what you most want to change is "skin quality" or "shape."

To gradually refine fine lines, skin texture, and firmness: PN injection becomes a candidate.[3][1]

To also supplement dryness and luster: there is an approach of combining PN and hyaluronic acid.[2][6]

To clearly fill hollows and depressions: the discussion shifts to volume-enhancing hyaluronic acid fillers.[1][7]

PN research is noted to have variable quality, and results should be approached cautiously.[4]When choosing, be sure to ask your provider to distinguish between what can be expected and what remains unknown.

What should you check during consultation?

Which is right for you cannot be decided from an article alone. Whether skin firmness has declined or hollowness is present is determined by actually examining your skin.

During consultation, confirm whether the injectable contains PN alone or combined with hyaluronic acid, how many visits you are planning, and what to do if bruising appears.
