VT Cosmetics, PDRN and exosomes are three separate ideas that K-beauty marketing has blurred into one, and understanding what each one actually does is the difference between a routine that works and a shelf full of expensive serums. VT Cosmetics is a Korean brand; PDRN is an ingredient; exosomes are a category of cell-signalling messengers still early in its evidence. This guide separates them honestly — what the research supports, what it doesn’t, what these products can realistically do at home, and where the professional versions differ. If you’re looking for the in-clinic side of this conversation, that lives on our exosomes Montreal page. You can shop the range discussed here at our sister store, Skincare Lab.

What this article covers

What is VT Cosmetics — and is it the same thing as V-Tech?

No, and this is worth clearing up first because the two names get searched interchangeably and they are completely unrelated. VT Cosmetics is a South Korean skincare and makeup brand that built its reputation on Cica (Centella Asiatica) formulas for sensitive, reactive skin, gained mainstream visibility through collaborations with BTS and LINE Friends, and became genuinely famous for the Reedle Shot. Everything VT makes is an at-home cosmetic you buy in a bottle.

V-Tech is something else entirely: an Italian premium exosome complex used inside professional treatments, applied by a technician during microneedling. It is not sold as a home product, it is not Korean, and it has no connection to VT Cosmetics beyond an unfortunate similarity in the abbreviation. If you searched “VT PDRN” hoping to find a clinic treatment, or “V-Tech exosome” hoping to buy a serum, you’ve landed on opposite sides of the line.

What is PDRN, and what does “salmon DNA” actually mean?

PDRN stands for polydeoxyribonucleotide — purified fragments of DNA, most commonly extracted from salmon milt. The reason salmon is used rather than something more glamorous is unromantic and practical: salmon DNA is structurally close enough to human DNA that skin cells recognise the fragments rather than treating them as foreign material, and the supply is abundant and cheap. “Salmon DNA” is accurate, not a marketing flourish — and worth knowing if you avoid animal-derived ingredients, because PDRN is not vegan.

PDRN began in regenerative medicine, where it has been studied for decades in wound healing and tissue repair. What K-beauty did was reformulate it for topical use, where the claims are narrower and honest: soothing, hydration, a plumper and more comfortable-looking surface. That’s the realistic scope. A PDRN essence is not going to remodel scar tissue through intact skin.

That last point is the one most articles skip. Topical PDRN works at and just below the surface. It is comfortable, it is pleasant, and it genuinely improves how skin looks and feels over weeks of use. It is not a needle-free version of a clinical procedure, and any brand implying otherwise has crossed from cosmetic claims into drug claims.

Is topical PDRN the same as a PDRN injection?

No, and the gap between them is larger than the shared name suggests. Injectable PDRN — the “salmon DNA skin booster” — is a regulated clinical procedure in which the compound is deposited below the skin’s surface by a qualified provider. Delivery is complete, dosing is controlled, and the clinical evidence base behind the injectable form is decades deep. A topical PDRN serum or cream is a cosmetic: absorption is partial, the effect is gentler, and the evidence for the topical form specifically is still emerging.

Both are legitimate; they just answer different questions. Use topical PDRN for what it is — a comfortable, hydrating step that plays well with almost everything else in a routine. If what you actually want is the clinical outcome, that’s a consultation conversation, not a shopping one.

How do the PDRN products compare across brands?

PDRN has become the most crowded ingredient story in K-beauty, and the honest answer is that the differences between brands are smaller than the packaging suggests. What genuinely varies is the concentration tier, the delivery format, and what else is in the bottle. Here’s how the main options actually differ — named factually, with no claim that one is medically superior to another.

A note on the numbers you’ll see on the packaging — 100, 2000, 7500. These are brand-specific intensity or concentration markers, not a standardised unit, so a “7500” from one company is not comparable to a “7500” from another. Treat them as a within-brand ladder only.

Is the Reedle Shot really at-home microneedling?

It is not, and this is the single most oversold claim in the category. The Reedle Shot is a serum loaded with spicules — microscopic, needle-shaped silica structures, mineral- and marine-derived, roughly 15 micrometres across, which is smaller than a pore. Pressed onto clean, dry skin, they lodge in the outermost layer and create microscopic channels. That does two useful things: a gentle, non-abrasive exfoliation of dead surface cells, and temporary pathways so whatever you apply next absorbs better.

Clinical microneedling is a different procedure. It uses fine metal needles that reach into the dermis to trigger a controlled wound-healing response, which is what actually builds collagen. The Reedle Shot never gets past the stratum corneum and upper epidermis. Nothing punctures deeply, there are no metal needles, and the spicules themselves aren’t an active ingredient — they aren’t absorbed, and they shed naturally over two to three days. Cleveland Clinic’s overview of microneedling is a good reference for what the clinical procedure involves, and the contrast is obvious once you read it. If you want the real, deeper version, that’s a service — see our microneedling page.

None of which makes the Reedle Shot a bad product. “Surface stimulation that exfoliates gently and boosts absorption” is a real, useful thing for a serum to do. It just isn’t collagen induction, and buying it expecting clinical results is how a perfectly good $35 serum ends up feeling like a disappointment.

Reedle Shot 100 vs 300 vs 700 — what do the numbers mean?

The numbers indicate spicule intensity, not a different mechanism. Higher number, more spicules, stronger tingle. There’s no additional active being unlocked at 700 that the 100 lacks — you are simply choosing how much surface stimulation you want in one application.

The lineup also splits by supporting ingredient rather than by strength: Collagen leans toward firmer, bouncier-looking skin; Vita-Light targets dullness and uneven tone; Reti-A adds a retinal element for texture and the look of fine lines; and Pro Cica is the calming, Centella-heavy option for reactive skin, currently stocked as a two-step mask rather than a serum. All share the same spicule mechanism — the difference is only what you’re delivering alongside it. Treat Reti-A like any retinoid: introduce it slowly, expect more sensitivity, and skip it during pregnancy or breastfeeding.

Where do exosomes fit in — and do they actually work?

Exosomes are tiny vesicles that cells use to send signals to one another, and the working theory is that they can prompt skin cells toward more youthful behaviour. It’s a genuinely interesting area. It is also, honestly, the least settled of the three ideas in this article. Most published support comes from lab and preclinical work plus small case series; systematic reviews from early 2026 describe promise while explicitly calling for larger controlled trials. Older options such as PRP still have the stronger randomised evidence base.

The safety picture deserves precision rather than alarm. No exosome product is approved for injection in Canada or the United States. The serious adverse events that have made the news overwhelmingly involve injected exosomes administered by unregulated providers — not topical, over-the-counter cosmetics. The FDA’s consumer alert on regenerative medicine products is worth reading before you consider exosomes anywhere. Health Canada draws the same line: a product applied to the surface with no therapeutic claim is a cosmetic; the moment it’s injected or marketed to treat a condition, it becomes a regulated drug.

How do I actually use these products together?

The order matters more than people expect, and the most common mistake is applying a spicule serum to damp skin, where it simply doesn’t work properly.

On combining with strong actives: you can, carefully. Because the Reedle Shot improves absorption of whatever follows, it also amplifies irritation potential. Don’t introduce a spicule serum and a brand-new retinoid or acid in the same week. On spicule nights, keep the rest of the routine simple and hydrating, and alternate your strong actives across different evenings rather than stacking them. And don’t use it on the same night as a device, or in the days immediately after an in-clinic treatment.

Who should skip these products?

A brand willing to say who a product isn’t for is one worth trusting. Postpone or avoid spicule products entirely in the following situations.

How much do these products cost, and where do you buy them?

Current pricing from our sister store, Skincare Lab, confirmed at the time of writing and quoted in USD. Promotions change — confirm the latest figure on each product page.

If you’d rather test the sensation before committing to a full bottle, the cheapest entry points are the single-use masks and travel sticks: the PDRN Hydrogel Mask and the Reti-A two-step mask are around $7 each, the Collagen Reedle Shot mask about $5, and the Reedle Shot 300 travel sticks are $21 for ten. Beyond VT, the broader PDRN and exosome shelf is worth browsing too.

At-home K-beauty vs in-clinic treatments — when should you see a pro?

These aren’t rivals; they’re rungs on the same ladder. Spicule serums, topical PDRN and topical exosomes are a genuinely good, low-cost way to maintain and enhance skin between clinic visits — or instead of them, if your concerns are mild. Where surface cosmetics run out of road is depth: significant texture, scarring, laxity and established pigment all live below the layer a cosmetic can reach.

That’s where professional treatments come in — real microneedling, RF microneedling, microneedling-assisted exosome and booster protocols, and clinical facials. If you’re curious what’s realistic, our before-and-after gallery is a reasonable place to start. The American Academy of Dermatology’s guidance on cosmetic treatment safety is also worth a read before booking anything, anywhere.

One more regulatory note, since it governs everything above. VT’s serums, creams and masks are sold as cosmetics, regulated in Canada by Health Canada under the Food and Drugs Act and the Cosmetic Regulations. Cosmetics may make appearance- and feel-based claims — smoother, brighter, hydrated — but not therapeutic ones like “treats” a condition or “regrows” hair. Importers must also notify Health Canada of the cosmetics they sell. Topical equals cosmetic; injected or therapeutic equals regulated drug. That line explains most of what this article has said.

What makes the at-home advice at IPL Lab different?

We sell K-beauty products and we perform the clinical treatments they’re modelled on, which puts us in an unusual position: we have no incentive to oversell either side. When a $35 serum is the right answer, we’ll say so. When it isn’t, we’ll say that too, rather than letting you spend six months on a routine that was never going to reach the problem.

Our clinics in the Plateau in Montréal and in Laval run the professional versions of everything discussed here, including topical exosome and peptide protocols delivered by microneedling. Consultations are free, include a Skin analysis, and come with a straight answer about whether your concern belongs in a bottle or in a treatment room.
