How to compare with what you use.

The chemistry of CE-marked HA fillers is much the same. What differs is the price per ml, whether there is stock in the country, and who answers when something goes wrong. Ten questions to take to your current supplier, with Sofiderm's answer beside each.

The five Sofiderm lines
Before you start

Same base, three differences.

Hyaluronic acid cross-linked with BDDE, class III, a notified body. Up to that point almost every CE-marked brand looks alike. The useful comparison happens on three other points: what the supplier will show you in writing, what each ml actually costs after discounts, and who picks up the phone during an adverse event.

Three proofs

What to ask any supplier.

AskData sheet and DoCCE certificate in force, declaration of conformity and a data sheet with concentration and cross-linker. If your current supplier will not give you those, that is the first difference.
TestOne line, one week, side by sideNo minimum order. Compare flow through the needle, behaviour in the tissue and the patient's response in the same plane.
CountCost per session, not per syringe10 and 20 ml for high-volume clinics; volume tiers by quantity, in any combination.
