How to Check the Authenticity of Injectable Products at a Skin Clinic

Ask to see the sealed box or syringe before injection, check the brand name, lot number and expiry date, and confirm the product is approved by Korea's Ministry of Food and Drug Safety (MFDS). A reputable clinic will open the package in front of you and note the product in your record. If a clinic refuses, consider going elsewhere.

Asking to See the Product Is Normal in Korea

Korea has a large injectables market, with many domestic and imported brands of botulinum toxin, hyaluronic acid filler and skin boosters. Most clinics use genuine, approved products, but asking to see the package is a sensible habit, especially when you are travelling and comparing quotes.

Five Things to Check on the Package

You do not need to be an expert. A quick look at the label tells you most of what you need to know.

1. Brand and product name It should match the name written in your treatment plan and quote.
2. Sealed packaging The box or blister should be closed and opened in front of you.
3. Lot or batch number This links the product to its manufacturing record.
4. Expiry date The product should be within its use-by date.
5. Amount Units for botulinum toxin, cc or syringes for fillers and boosters.

Many filler and booster brands include small traceability stickers in the box that clinics can attach to your record. Ask whether you can have one or take a photo of the label.

Different Injectables Look Different in the Treatment Room

Knowing how each type of product usually arrives helps you know what to look for.

Botulinum toxin is often prepared in advance because it must be mixed. It is reasonable to ask which vial was used and to see the brand on the box.

Approval in Korea Means the Product Has Been Reviewed

Medicines and medical devices used in Korean clinics must be approved by the Ministry of Food and Drug Safety. Botulinum toxin is regulated as a medicine, while fillers and many skin boosters are regulated as medical devices. Approved products have known ingredients, manufacturing standards and safety data.

An approved product, a careful doctor and clear records work together.

If you see a brand you do not recognise, simply ask the clinic whether it is approved in Korea and what it contains. You can read more about the products we use on our botulinum toxin and hyaluronic acid filler pages.

Brand Names You May Hear in Seoul

Visitors are often surprised by how many brands are available in Korea. Knowing a few names makes the conversation easier, but the brand matters less than using an approved product in the right amount, placed by an experienced doctor.

If you have a preference, for example because you had a brand at home and liked the result, tell the clinic when you book so they can confirm it is available.

Very Low Prices Deserve a Closer Look

Prices for injectables in Seoul vary a lot. Some differences come from brand choice, amount and who performs the treatment. A price that is far below others, however, is a reason to ask more questions.

• Is the quoted brand the one that will actually be used?
• Is the amount the same as in other quotes?
• Is the product diluted more than usual?
• Is a different, cheaper brand used for part of the treatment?

Comparing written quotes that list brand and amount is the simplest way to compare fairly.

Your Record Should Show What Was Injected

After treatment, your record should note the product, amount, area and, ideally, the lot number. This matters for your safety. If you have a reaction later, or want the same treatment at home, a doctor will need to know exactly what was used.

Warning Signs Worth Taking Seriously

Most clinics in Gangnam are transparent about products. A few signs suggest you should pause and ask more questions, or consult elsewhere.

• The clinic will not tell you the brand or amount.
• The product is already opened or unlabelled when you arrive.
• The plan says one brand but staff mention another on the day.
• Injections are offered outside a medical clinic, such as at a salon or private home.
• The price drops sharply when you hesitate, without any change in the plan.

Injectables Belong in a Medical Clinic

In Korea, injecting botulinum toxin, fillers and skin boosters is a medical procedure that should be performed by a doctor in a licensed medical facility. Treatments offered in beauty salons, hotel rooms or private homes are a serious safety risk, both because of product quality and because complications may not be recognised or treated in time.

If you are approached through social media with an unusually cheap offer, check where the treatment will happen and who will perform it before agreeing.

Proper Storage Matters Too

Authenticity is not only about the brand. Some injectables, particularly botulinum toxin, need to be stored at controlled temperatures. Products that have been stored badly may work less well. Reputable clinics follow the manufacturer's storage instructions and use products within their recommended time once opened. You do not need to inspect the fridge, but buying from a licensed clinic rather than an informal seller protects you here too.

Checking the product takes a minute and gives you peace of mind. Combined with a careful doctor and clear aftercare, it is one of the easiest ways to make your treatment in Seoul safer. For more answers, visit our FAQ page.
