How do the three skin-booster categories differ?
The names are not interchangeable. Compare the stated material category first, then ask the clinic to identify the exact product, formulation, regulatory status and treatment plan before consenting.
| Category | How this guide identifies it | What to verify at consultation |
|---|---|---|
| Polynucleotide-based | Products described as using purified DNA fragments. | Exact product, approved use and proposed session plan. |
| Exosome-based | A newer category marketed around cell-signaling material, sometimes paired with another procedure. | Product source, regulatory status and what procedure delivers it. |
| PDLLA-based biostimulator | Products such as Juvelook described as collagen-stimulating rather than a simple filler. | Exact formulation, dilution, intended outcome and aftercare. |
Polynucleotide-based boosters (Rejuran and similar)
Rejuran is probably the best-known example of a polynucleotide-based injectable, derived from purified DNA fragments and marketed for improving skin texture, elasticity and overall tone through a healing-and-regeneration mechanism rather than volumizing. These are typically delivered as a series of sessions rather than a single treatment, with cumulative improvement reported over the course of a few months.
Exosome-based treatments
Exosome treatments are a newer, more actively evolving category, generally marketed around cell-signaling molecules intended to support skin repair and regeneration, often paired with microneedling or laser treatments to enhance absorption. Because this category is newer and product sourcing varies significantly between clinics, it's worth asking more detailed questions here than for more established treatment categories -- including where the product is sourced and what regulatory approval it carries.
Other biostimulator categories, including Juvelook
Juvelook and similar poly-D,L-lactic acid (PDLLA) based products fall into a biostimulator category aimed at gradually encouraging the skin's own collagen production, positioned somewhere between a simple filler and a longer-term regenerative treatment. As with the other categories here, the right choice depends heavily on your specific skin concern, and a consultation with a licensed dermatologist should guide the decision rather than a general comparison like this one.
Cost also varies meaningfully across these categories and between clinics offering the same named product, partly reflecting differences in product sourcing and dilution -- always ask specifically what concentration or formulation is being used rather than assuming all products marketed under the same brand name are identical.
Ask directly how many sessions your provider recommends for your specific concern, since these biostimulator categories are rarely a one-visit treatment, and results build gradually across a series rather than appearing after a single appointment.
