A treatment can be popular and still be wrong for your skin. Polynucleotides, injectable skin boosters and microneedling may all support skin quality, but they are not interchangeable and none is a substitute for proper assessment.

Polynucleotides

Polynucleotide products are injectable preparations intended to support the skin’s repair environment. They are commonly chosen for delicate, crepey or tired-looking skin, including the under-eye area, where adding volume may not be desirable.

The evidence base is developing and products are not identical. Source material, formulation, device status and the published evidence for the exact product all matter. Expect a course rather than an instant transformation, and temporary bumps, swelling or bruising after injection.

Injectable skin boosters

Skin boosters usually use hyaluronic acid in a formulation designed primarily for hydration and skin quality rather than projection or contour. They can improve the way dehydrated skin reflects light and may soften fine textural change.

A skin booster is still an injectable medical device. Vascular occlusion, infection and inflammatory reactions remain possible; the word ‘booster’ does not make it a facial.

Microneedling

Microneedling creates controlled micro-injury to stimulate a wound-healing response. It is often useful for texture, pores, superficial scarring and overall skin resilience. Needle depth, device quality, sterility and the product applied to freshly needled skin are important.

It does not replace lost volume and should not be performed through active infection, uncontrolled inflammatory skin disease or without considering pigmentation risk and healing capacity.

How we decide

For fragile under-eye skin, an injectable regenerative approach may be considered. For dehydration, a skin-quality injectable may be more logical. For acne scarring or uneven texture, a controlled microneedling plan may be more appropriate. Sometimes the safest answer is skincare first, or no procedure at all.

  • What is the main concern: hydration, texture, laxity, scarring or volume?
  • How much downtime is acceptable?
  • Is there a medical, medication or skin-history reason to delay?
  • Is the proposed product licensed or appropriately marked for its intended use?

The bottom line

The best treatment is the one matched to the tissue, the concern and the evidence, not the name currently appearing most often online.
