Where do these myths come from
The skin booster market is growing fast. Wherever demand grows, so do offers of "almost the same, but cheaper". The problem is that injectable products aren't cosmetics off a shop shelf. The difference between an original and a substitute is often invisible to the naked eye — it only shows up in the salon, or weeks after the treatment. Marketing adds to the confusion: cleverly worded ingredient descriptions, certificates from countries with looser standards, and sales through intermediaries who have no idea how the product was stored. Before the myths — one fact about how the whole approval chain actually works.
Six myths, one by one
MYTH 1: "The formula is identical, so the effect must be the same." Fact: the label tells you what is in the vial — not how it was manufactured, or how pure it is. One injectable hyaluronic acid can differ from another in the degree of cross-linking, molecular weight, residues left over from the cross-linking process and — crucially — the level of bacterial endotoxins. This last factor, completely invisible on the label, determines whether inflammation develops after the treatment. The same active ingredient name isn't enough to call two formulas "identical".
MYTH 2: "A CE mark guarantees quality." Fact: a CE mark confirms compliance with certain standards — but those standards vary hugely depending on how the product is registered. A Class III medical device (highly regulated), a Class I device (lightly regulated), a dietary supplement, a cosmetic — all of these can carry a CE mark, yet the requirements for sterility, clinical trials and post-market surveillance differ enormously between them. The real question isn't "does it have a CE mark", but "which class is it registered under, and who issued the certificate".
MYTH 3: "It's just a skin booster, not a medicine — so the standards aren't as strict." Fact: subcutaneous injectable products come into direct contact with tissue, regardless of whether they're formally classed as a medicine or a medical device. The body doesn't distinguish between "just a skin booster" and "a medicinal product" when it comes to inflammation, infection or granuloma formation. Every substance delivered by injection must meet exacting sterility standards — not because marketing says so, but because the skin is no barrier at all against anything introduced this way.
MYTH 4: "If an online shop sells certified products, it must be allowed to sell them." Fact: legal distribution channels for aesthetic injectables are strictly defined. In Poland, only healthcare entities and doctors are allowed to purchase them. Retail sale online breaches these regulations, which means products available "to anyone" online are either counterfeit or have been diverted outside the legal supply chain. "Available to buy online" doesn't mean "safe to use" — and it doesn't mean it comes from the same batch as the product you'd receive in a certified salon.
MYTH 5: "A cheaper product plus a pricier session evens out." Fact: a treatment is more than a substance. It's technique, anatomy, injection point and the experience of the person holding the needle. But the product itself isn't neutral either — its rheology (density, flow, so-called spread) determines how it distributes through tissue and how long it stays active. A product with poor rheology, even in the hands of an experienced specialist, won't give a predictable result. No doctor can "rescue" a poor substance through technique alone.
MYTH 6: "If it goes wrong, it can always be reversed." Fact: this is true for hyaluronic acid — hyaluronidase, an enzyme that dissolves it, exists — but not for every skin booster. Polynucleotides, collagen biostimulators and exosomes have no simple antidote. That means a low-quality or poorly administered product can cause inflammation or an unsatisfactory result that takes a long time and multiple treatments to correct — not a single "touch-up". This is another reason why product quality is part of the treatment plan, not just a budget question.
When should a red flag go up
The market is large, and new offers appear faster than regulators can verify them. Still, there are warning signs worth pausing for — or simply reasons to choose somewhere else.
What sets an original apart — in practice
You don't need to understand polymer chemistry to ask the questions that really test a salon. Three questions worth asking before any treatment involving an injectable substance: Which product will be used, and how is it registered? Where does it come from, and how was it stored? Can I see the batch documentation on request? A salon that answers clearly and without hesitation has something to say. A salon that changes the subject, or tells you "it doesn't matter" — has just told you everything you need to know.
It's also worth knowing that different biostimulators work differently, and on different timelines. Hydrating hyaluronic acid (a typical skin booster) works relatively fast, but the effect is temporary. Polynucleotides, exosomes and collagen biostimulators trigger the skin's own repair processes — results build over several weeks to a few months, and last longer, because they come from tissue remodelling rather than an external substance simply being present. This distinction matters when planning a course of treatment — and it's another reason why choosing a product requires a consultation, not just "trying something cheaper".
Where it genuinely makes sense to save money — and where it doesn't
Aesthetic medicine doesn't have to be reserved for a select few — that's not the point of this article. The point is that some areas are worth looking for savings in, and some aren't. Fewer treatments, well chosen, with a certified product? A sound strategy. More frequent treatments with a cheaper substance "on trial"? A strategy that statistically ends up costing more — financially and in terms of health — than any savings made along the way. A good doctor will build you a plan that matches an ambitious goal to a realistic budget, without compromising on product safety. Ask directly: "how do I achieve X with a budget of Y?" The answer will be more honest than any price comparison online.
