A skin booster is a category of injectables, not one product
Hyaluronic acid, PN, PDRN, PDLLA and exosome products all sit under the same Korean label despite different active ingredients. So a clinic saying it offers skin boosters does not tell you what you would be injected with.
Last checked:
A skin booster is an umbrella term for injecting hydrating or regenerative ingredients into the skin, covering product families whose active ingredients differ entirely.
“Skin booster” names neither a product nor a single technique. Products with different mechanisms and different goals are collected under one word, which means a clinic listing “skin boosters” does not settle what you would actually receive.
Classification by active ingredient
The stated purposes below are manufacturer and clinic wording, not approved indications.
| Family | Active ingredient | Product names as clinics list them | Stated purpose |
|---|---|---|---|
| Hyaluronic acid (HA) | Lightly cross-linked or non-cross-linked HA | Water shine injection, Skinvive, Belotero Revive, Hyalier | Hydration, skin texture |
| PN / PDRN | Salmon-derived polynucleotides | Rejuran (Healer, HB, S), salmon injection | Regenerative environment, fine lines, elasticity |
| PDLLA | Poly-D,L-lactic acid microparticles with HA | Juvelook, Juvelook Volume, Rejuvelook | Collagen stimulation, firmness, volume |
| Exosome / culture media | Cell-derived vesicles, stem cell culture media | Exosome, Restem exosome | Regenerative signalling, often adjunctive |
| hADM / ECM | Human acellular dermal matrix, extracellular matrix | Rituo, Cellderm | Replenishing dermal components, firmness |
Different families imply different injection depths, intervals and session counts. That is why “I had a skin booster” describes a different procedure from one person to the next.
Where PDRN ends and PN begins
Both are salmon-derived DNA polymers, yet the two terms are used interchangeably in the literature and the market. A 2025 review in Biomolecules proposed a 1500 kDa cut-off to resolve this — PDRN below it, PN at or above it. The academic vocabulary is still being settled, so divergent clinic wording is to be expected.
How far the labelling actually varies
Counted from the official websites of seven clinics in Gangnam, Seocho and Cheongdam on 24 August 2026.
| Clinic | Products named |
|---|---|
| GU Clinic (9) | Rejuran · Juvelook · exosome · PDRN · Rituo · water shine · Skinvive · Cellderm · Belotero Revive |
| Ruby Clinic Yangjae (6) | Rejuran · Juvelook · exosome · PDRN · Rituo · water shine |
| Cheongdam Rituo Clinic (5) | Rejuran · Juvelook · exosome · Rituo · water shine |
| View Plastic Surgery (5) | Rejuran · Juvelook · exosome · Rituo · water shine |
| Refine Clinic (5) | Rejuran · Juvelook · PDRN · Skinvive · Belotero Revive |
| Iz Clinic (5) | Rejuran · Juvelook · exosome · PDRN · water shine |
| Cheongdam Routine Clinic (0) | — |
Zero does not mean no skin booster pages. Cheongdam Routine Clinic published 23 skin booster pages without naming a product. Volume of material and specificity of labelling are separate measures.
What to verify
| What | Why |
|---|---|
| Product name | You cannot compare mechanism or session design until the family is known |
| Regulatory category | Products are approved variously as devices, drugs or cosmetics |
| Approved indication | Some products carry a narrow approved purpose |
| Genuine-product and dosage disclosure | Whether it is stated at all varies by clinic |
Exosome and culture-media products are frequently adjunctive rather than stand-alone injectable drugs. Asking for the family together with the regulatory category is the practical question.
From the source
Some clinics list every product name, some list two or three, some write only “skin booster” — so the phrase “we do skin boosters” does not tell you what you will receive.
(…) Some products are approved as medical devices, some as drugs, and some carry a narrow approved purpose (…) it is worth asking for the product name together with its regulatory category and approved indication.

Frequently asked questions
Is a skin booster a single treatment?
No. It is an umbrella term for injecting hydrating or regenerative ingredients into the skin. Hyaluronic acid, PN and PDRN, PDLLA, exosome and culture-media products, and hADM/ECM products all sit under the same label despite different active ingredients.
Are PDRN and PN the same thing?
Both are DNA-derived polymers, but they differ in molecular weight. A 2025 review in Biomolecules proposed a 1500 kDa cut-off to settle the terminology, calling anything below it PDRN and anything at or above it PN.
What should I check in a clinic listing?
Whether the product is named, and what regulatory category and approved indication that product holds. Across seven clinics in Gangnam, Seocho and Cheongdam checked on 24 August 2026, the number of products named ranged from nine down to zero.
