Counterfeit and grey-import injectables exist, and they look convincing. This page sets out how IN Eternity Clinic on Orchard Road obtains, stores and records every injectable Dr Sin Yong uses, and what you can ask any clinic.
WhatsApp to Enquire →Key facts ↓At IN Eternity Clinic, every filler, skin booster and anti-wrinkle injection is bought directly from its Singapore registrant or an authorised distributor, never from overseas websites or parallel importers. Temperature-sensitive products are kept in monitored refrigeration, and each product’s batch number is recorded in your notes so it can be traced if a question ever arises.
Counterfeit fillers and anti-wrinkle injections are sold online and through informal channels, often in packaging that looks almost identical to the genuine product. Their content, sterility and strength are unknown. Unlicensed botulinum preparations have caused serious illness abroad, and unknown fillers can cause infection, lumps and inflammatory reactions that are difficult to treat.
Grey imports are a subtler problem. These may be genuine products bought overseas and brought in outside the authorised channel. Even if the contents are real, there is no assurance about how they were stored or transported, and the local registrant cannot vouch for them or manage a recall.

Every injectable used at IN Eternity Clinic is registered in Singapore and bought directly from its local registrant or an authorised distributor. Each delivery comes with documentation that links the product and batch back to that supplier. The clinic does not buy from overseas websites, from other clinics or from parallel importers, and does not inject products patients bring in themselves.
Dr Sin Yong also keeps the range deliberately small. Using fewer products, well understood and well documented, makes both the medicine and the record-keeping safer. More on what registration means is on the HSA registration guide.
“If I cannot trace a product back to its registered supplier, I do not inject it. A familiar box is not the same as a known source.”
Some injectables are sensitive to temperature. Botulinum toxin, for example, must be kept within a refrigerated range from the manufacturer to the clinic and until it is prepared. Products arriving outside their required conditions are not accepted. At the clinic, temperature-sensitive products are stored in monitored medical refrigeration, separate from food or other items.
Fillers and skin boosters have their own storage requirements, which are followed as labelled. Once a product is prepared, it is used within the time the manufacturer specifies and then discarded, rather than kept for another day.

Before use, the box, seals, expiry date and batch number are checked. Where a product comes with peel-off traceability labels, these go into your record; otherwise the product name and batch number are written in. If you ask, you will be told exactly what was used. If a manufacturer or HSA ever issues a safety notice about a batch, these records allow the clinic to identify who received it.
Your notes also record the amount used and where it was placed. This matters for future treatment, and for filler correction if it is ever needed.
What is the exact product, and is it registered in Singapore? Who supplies it? Will the batch number go into my record? Who will inject it, and are they a doctor? A clinic using genuine, properly sourced products should answer all four without hesitation. Very low prices for branded injectables, products shown already opened, or reluctance to name the product are reasons to pause.
The aesthetic clinic red flags article covers other warning signs, and the safety page explains the clinic’s wider safety practice.
Ask for the exact product name, check that it is registered with HSA, and ask whether the batch number will be recorded in your notes. A clinic using properly sourced products can show you the packaging and registration details. Unusually low prices or vague answers are reasons for caution.
No. Products brought in by patients cannot be verified for source, storage or authenticity, even when the packaging looks genuine. They are therefore not used. Every injectable at IN Eternity Clinic comes through its authorised local supplier, with documentation that traces each batch.
A product, possibly genuine, bought outside the authorised local supply chain, for example from an overseas seller. Its storage and handling cannot be verified, and the local registrant cannot support it or manage a recall. IN Eternity Clinic does not use grey imports.
Some injectables, including botulinum toxin, can lose potency or change if stored outside their labelled temperature range. A product that has been left warm in transit may look normal but behave unpredictably. Correct storage from manufacturer to clinic helps ensure the product works as expected.
Yes. The product name and batch number are recorded in your medical notes, and you can ask for them at any time. This is useful if you later see another doctor, need a correction, or if a manufacturer issues a notice about a particular batch.
Products from authorised channels can cost more than unverified alternatives. Fees reflect the product, the amount used and the doctor’s time, and are explained at consultation. A price far below the usual range for a branded product is worth questioning.
