The regenerative skincare category has grown fast enough that the terminology has started to blur — PDRN, polynucleotides and skin boosters get used almost interchangeably online, despite meaningful differences in what each is actually built from and how it behaves in skin.
Classic hyaluronic acid boosters
Standard skin boosters are lightweight hyaluronic acid formulations designed to hydrate and improve elasticity without adding volume. Profhilo is the best-known example — a slow-release HA that spreads and remodels skin quality across the whole face, with Profhilo Haenkenium a newer variant built for more mature skin specifically.
Polynucleotides: a different mechanism
Polynucleotides work differently again — derived from DNA fragments, they’re understood to support tissue repair and stimulate the skin’s own regenerative processes rather than simply drawing in moisture. Patients considering the treatment often ask whether polynucleotides actually work, and the honest answer is that results are gradual and cumulative rather than immediate — closer to a skin-quality investment than a single transformative session.
PDRN: the newest generation
PDRN (polydeoxyribonucleotide) is closely related to polynucleotide technology and sits behind some of the newest products on the market, including LongevHA and ElysiHA — with ElysiHA Eyes built specifically for the periocular area, where skin is thinnest and most sensitive to treatment. Understanding what LongevHA actually does is worth a proper read before booking, since the mechanism genuinely differs from a standard booster course.
Building a plan across categories
For patients building a longer-term skin quality plan, these categories aren’t mutually exclusive — a classic HA booster course alongside periodic PDRN treatment is a common combination, addressing hydration and regeneration through two different pathways rather than picking one and hoping it covers everything.
What to ask before choosing
The one question worth asking any clinic offering these treatments: what is this actually made from, and what’s the evidence behind that specific mechanism — not just “is it good,” but what it’s built to do.
