Which skin booster is right for you depends on what your skin is short of: repair signals, hydration, firmness, energy or structure. Exosomes, PDRN, PLLA, NAD+ and peptides each answer a different one of those, and all of them are only as useful as the delivery method underneath them. That is why every booster we offer rides on microneedling Montreal clients already know, and why our exosomes Montreal program is built as a menu rather than a single miracle serum. This guide walks through each booster honestly, what it can and cannot do, how the Italian V-Tech system from Promoitalia fits in, and which one makes sense for which concern.

What this article covers

How does a topical skin booster actually get into the skin?

On intact skin, almost none of it does. The stratum corneum, the outermost layer, is built to keep large molecules out, and exosomes, DNA fragments and most peptides are far too big to pass through on their own. That is the whole reason skin boosters are paired with microneedling: the needles create thousands of temporary micro-channels, a few hundred microns deep, that stay open for a short window after the pass. Applied in that window, a booster reaches the upper dermis instead of sitting on the surface.

It matters to be precise about the word “topical” here. In Canada, a skin booster applied to needled skin is a cosmetic-grade product used to support a procedure. It is not an injectable, it is not a drug, and it should not be sold as either. The distinction is not a technicality. Injected exosomes from unregulated sources are where the serious adverse events in the literature come from, and the FDA has issued a consumer alert about exactly that. Everything described below is applied to the surface after needling, full stop.

Because the delivery step is the same for every booster, the real decision is what you put in the channels. The rest of this guide is about that choice.

What are exosomes, and what do they actually do on skin?

Exosomes are tiny vesicles, roughly a thousandth the width of a hair, that cells use to send instructions to one another. Packed inside are growth factors, proteins and short RNA sequences that can nudge nearby cells toward repair, calm inflammation and support collagen production. In a skin-booster context, the exosomes are either derived from cultured cells (typically plant or lab-grown human cell lines in the Korean products we use) or built synthetically to mimic that signalling, as in the Italian V-Tech line.

The honest evidence picture: early. Preclinical work and a growing set of small case series and split-face studies are promising for texture, redness and post-procedure recovery, and systematic reviews published in early 2026 said the same thing while calling for larger, better-controlled trials. PRP, by comparison, has a longer track record in randomized studies. So we position exosomes as an enhancer of what microneedling already does, not as a treatment in their own right. If you want the deep dive, our companion article on what exosome therapy is and whether it works goes into the research in more detail.

What is PDRN, and why is it called the “repair” booster?

PDRN stands for polydeoxyribonucleotide: purified fragments of DNA, extracted from salmon, that happen to be structurally very close to human DNA. Skin cells recognise those fragments and respond by ramping up repair activity, which is why PDRN has a long history in wound care before it ever appeared in aesthetics. In the booster world it earns the “repair” label because the effect people notice first is not plumpness but calm: less redness, faster recovery, a more settled barrier.

Two things to know before you choose it. First, topical PDRN applied through micro-channels is a cosmetic product and is far milder than the injectable PDRN skin boosters marketed in Korea and Europe as “salmon DNA injections,” which are a regulated clinical procedure we do not perform. Second, it is salmon-derived, so it is not vegan and not suitable if you have a fish allergy. Ask, and we will swap it for a plant-based alternative.

What is PLLA, and how is topical PLLA different from the injectable?

Poly-L-lactic acid is a biostimulator. Rather than filling or hydrating, it prompts fibroblasts to build new collagen gradually over the weeks that follow treatment, which is why its results arrive quietly and keep developing after the course ends. It is the booster we reach for when the complaint is “my skin has lost its snap” rather than “my skin looks tired.”

The distinction that matters most: the PLLA we use is a topical complex delivered through micro-channels by a Derma Pen. It is the same molecule as the injectable PLLA fillers used by physicians for deeper volume restoration, but it is a different procedure with a different depth, dose and risk profile. Injectable PLLA is a reserved medical act in Québec and is not something an esthetic clinic performs. We say this plainly because the two are often blurred in marketing, and someone expecting filler-level volume from a topical booster will be disappointed. What you get instead is a progressive firming that suits early to moderate laxity along the jawline, cheeks and neck.

What does NAD+ do for skin, and how good is the evidence?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme every cell uses to generate energy and run its repair machinery, and its levels decline with age and UV exposure. The theory behind NAD+ boosters is simple: give tired skin cells more of the fuel they need, and they repair more efficiently. In practice, clients choose it for dull, “flat”-looking skin, fatigue-related sallowness and the kind of complexion that no amount of sleep seems to fix.

Here is where we are careful. NAD+ as a topical booster is the newest and least studied item on this list. Most of the supporting science concerns cellular NAD+ biology, oral precursors like NMN and NR, or in-vitro work; controlled studies of topical NAD+ delivered by microneedling are limited. We offer it because it is well tolerated and clients report a brightness they like, but we will not tell you it rebuilds collagen or reverses ageing, because nobody has shown that yet. Treat it as a finishing booster, layered onto exosomes or peptides, rather than the reason to book.

Which peptides are used in skin boosters, and what is GHK-Cu?

Peptides are short chains of amino acids, small enough to be absorbed through micro-channels and specific enough to carry a single “message” to skin cells. Signal peptides tell fibroblasts to make more collagen and elastin; carrier peptides deliver trace minerals the skin needs for enzyme activity; neuro-inhibiting peptides soften expression lines by quieting the nerve-to-muscle signal a little. A good booster blend layers several of these, and the ones described as biomimetic are engineered to mimic sequences the skin already recognises.

GHK-Cu, the copper tripeptide, is the best-known carrier peptide and the one people search for by name. It binds copper, which fibroblasts need to cross-link collagen, and it has a genuine research history in wound healing dating back decades. It is a strong ingredient for tone, hydration and a general “healthier skin” effect. What it is not is a lift: on its own, GHK-Cu will not tighten lax skin the way PLLA is designed to. If you have read about it and want it in your course, ask which peptides are in the blend at your consultation; our polypeptide protocol is customised to the skin in front of us.

Because peptides are gentle, well tolerated and comparatively affordable, the polypeptide course is our usual recommendation for a first microneedling series, for younger skin that wants prevention rather than correction, and for anyone who wants to see how their skin responds before committing to exosomes or PLLA.

What is V-Tech from Promoitalia, and how is it different?

V-Tech is a professional skin-renewal system made by Promoitalia, an Italian aesthetic-medicine manufacturer, and it is the one genuinely different protocol on this page. Where our standard exosome course is a Derma Pen plus a single booster, V-Tech pairs microneedling with fractional radiofrequency and delivers a concentrated ULTRA INTENSIVE serum that combines PDRN, synthetic exosomes, biomimetic peptides and plant-derived stem-cell extracts in one formula. It is Italian, not Korean, and it is not related to the VT Cosmetics K-beauty brand people sometimes confuse it with.

The radiofrequency is what changes the character of the treatment. RF heat in the deeper dermis adds a tightening stimulus on top of the mechanical needling, so V-Tech tends to suit skin that wants both texture correction and a firming component: post-acne scarring with some laxity, enlarged pores plus early jowling, or a generally “tired” complexion in the 40s and 50s. Sessions are spaced three to six weeks apart, longer than the standard course, because the RF component asks more of the skin between visits.

Promoitalia also makes LightEYES, the professional under-eye cocktail (hyaluronic acid, vitamin C, green tea, Ruscus aculeatus) we use for dark circles and puffiness. It is a booster rather than a full needling treatment, applied through a gentler multi-step protocol built for the thin skin around the eyes, and it appears in the price section below for completeness.

Which skin booster is right for you? A concern-by-concern guide

Most people do not need to memorise the biochemistry. They need to match a concern to a booster, and then let the consultation refine it. This is the table we use at the clinic, simplified.

Two combinations we steer people away from: stacking every booster in one session (more is not better, and it makes it impossible to know what worked), and choosing PLLA when the actual complaint is redness or dullness. Firmness is the slowest result to appear, and a client who wanted glow will not be patient enough to see it.

Is microneedling with a skin booster safe, and who should wait?

Microneedling itself is a well-established procedure with a good safety record when it is done with sterile, single-use cartridges by a trained operator. The booster layer adds two considerations: what is in the product, and how it is regulated. On the first, we use products with full ingredient lists, we patch-test anyone with a history of reactivity, and we treat salmon-derived PDRN as a declared allergen. On the second, Health Canada draws a line between cosmetics (topical, appearance claims) and drugs (injected, therapeutic claims), and every booster we use sits firmly on the cosmetic side of that line.

The one place to be extra deliberate is radiofrequency. In October 2025 the FDA issued a safety communication about RF microneedling devices after reports of burns, nerve injury and scarring, and the American Academy of Dermatology responded with guidance on training and device settings. That applies to the V-Tech protocol and to standalone RF microneedling, not to Derma Pen courses. It is one of the reasons we keep conservative settings, longer intervals and a consultation before every RF-based plan.

How much does microneedling with a skin booster cost? Every package

Pricing follows the booster and the number of sessions, and every course below is sold as a package because a single session of any booster shows you very little. All prices are current at the time of writing and are confirmed at your free consultation; each row links to its own product page.

Face — full-face booster courses

Targeted zones — lips, eyes, scalp

Radiofrequency microneedling — needling plus heat

PDRN, NAD+ and GHK-Cu are add-on layers or components of the blends above rather than separate packages; ask at consultation and we will price the combination. If you are deciding between a Derma Pen course and RF, our comparison of Dermapen microneedling versus RF microneedling lays out the trade-offs, and our microneedling before-and-after guide shows what a realistic timeline looks like. Members save on every course through our membership.

What makes a skin-booster course at IPLLAB different?

Three things, and none of them is a secret ingredient. First, we treat the booster as a choice, not a default: a consultation and skin analysis come before any course, and the booster is picked for the concern rather than sold as a bundle. Second, we are precise about what we do and do not do. Everything is topical and microneedling-assisted; we do not inject exosomes, PDRN or PLLA, we do not claim outcomes the research has not shown, and we tell you which treatments belong at a physician’s office instead. Third, we carry both a Korean exosome line and the Italian V-Tech and LightEYES systems from Promoitalia, so the recommendation can be driven by your skin rather than by whichever product happens to be on the shelf. Sessions are performed at our Plateau and Laval clinics by estheticians trained on every protocol, with the same sterile single-use cartridges and the same free consultation, and pricing is the same at both locations.
