Do serums used in microneedling have to be sterile?

No. Here is what the regulations actually require, what the word rests on when a supplier uses it, and what we do instead.

What the regulation requires

No cosmetic sold in the United States or Canada is a sterile product. No sterility certification exists for a cosmetic anywhere in either country, the FDA and Health Canada do not approve cosmetics at all, and no regulation requires a topical used in microneedling to be sterile. Any supplier offering you a sterile cosmetic is describing something that does not exist.

Sterility is a regulated state for drugs and devices, established by a validated process and confirmed by testing to a pharmacopoeial method. Cosmetics are held to a different standard: safety under normal use, good manufacturing practice, and microbiological limits and preservative efficacy testing. A serum can meet every one of those and still not be "sterile", because sterile is a claim about a product category it does not belong to.

Where the microneedling rules actually land

The rules that do exist are about who performs the procedure and how, not about the serum. Public-health guidance in Canada and state boards in the United States attach sterility to the needle and the cartridge. The one product-side rule is about dispensing: a fresh portion for each client, and nothing returned to the container.

Whether microneedling sits within your scope of practice is set by your state or provincial board, not by us, and it varies considerably. California prohibits skin penetration by estheticians entirely. Texas treats penetration of the dermis as a medical procedure requiring physician delegation. Other states permit it under a depth cap. The constraint is on the practitioner, not on any product.

Health Canada stated in its notice of 10 April 2026 that a product represented for administration by microneedling is not a cosmetic. FDA takes the same view of a topical promoted together with a microneedling device. That is why we make and sell our ampoules as professional leave-on cosmetic serums, publish no needling protocols or depths, and leave the procedure where it belongs: with the professional.

What "sterile" rests on when you see it on a label

We surveyed the professional microneedling serum market. Of the suppliers advertising a sterile serum, not one publishes a sterility test result, a sterilization method or a cleanroom classification to support it. We would rather give you our process than an adjective nobody in this category can document.

Three questions settle it with any supplier: which component was sterilized and how; what test result supports the word; and whether the word describes the container or the serum inside it. A supplier who answers all three plainly does not need the adjective.

What we do instead

The vials and stoppers are sterilized before filling. Each ampoule is filled and sealed immediately under a re-enterable stopper, so it is drawn from rather than opened. The serum inside is a cosmetic, not a sterile pharmaceutical, and we do not describe it as one.

What we can tell you is what the format is built for. A sealed ampoule drawn through a septum, one portion per treatment, is designed for the treatment room: post-procedure, on a compromised barrier, after resurfacing, wherever a fresh unopened portion matters more than a bottle that has been open for three months. How that fits your protocol is your clinical judgment.

Questions professionals ask

Does a serum used in microneedling have to be sterile?

No. No regulation in the United States or Canada requires it, and no sterility certification exists for a cosmetic in either country. The rules that exist attach sterility to the needle and cartridge and govern who may perform the procedure.

Is the Vegalab ampoule sterile?

The vials and stoppers are sterilized before filling. Each ampoule is filled and sealed immediately under a re-enterable stopper, so it is drawn from rather than opened. The serum inside is a cosmetic, not a sterile pharmaceutical, and we do not describe it as one.

What does "sterilized sealed ampoule" mean?

It means the glass and the stopper were sterilized before filling, the ampoule was filled and sealed immediately, and it is drawn through the stopper rather than opened. It does not mean the serum is a sterile product, and we do not describe it as one.

Is Vegalab registered with FDA? Is this product FDA approved?

Two different questions, and the honest answers are worth separating. FDA does not approve cosmetics. Not ours, not anyone's. There is no FDA approval, no FDA certification and no FDA certificate for a cosmetic product anywhere in the United States, and a brand implying otherwise is describing something that does not exist. FDA's own words are that cosmetic registration and listing "is neither a cosmetic approval program nor a promotional tool", and that FDA does not issue certificates for cosmetics. What does exist, since the Modernization of Cosmetics Regulation Act, is a mandatory filing: facilities register, and products are listed with their ingredients. It is a record that we exist and that this product exists. It is not a review, an endorsement or a quality mark. We are completing ours now and we will publish it on this page when it confirms. We would rather tell you that plainly than let a registration number do work it was never designed to do. What actually answers your question is documentation, and we will send any of it on request: the full ingredient declaration, the batch certificate of analysis for the lot you received, the microbiological results for that lot, and our declaration of conformity to ISO 22716, the international standard for cosmetic good manufacturing practice.
