Hyaluronic acid fillers compared

Hyaluronic acid fillers compared: Juvéderm, Belotero, Stylage, Saypha, Revolax and Singfiller

Anyone ordering Singfiller for the first time usually already works with another brand. The question is then almost always the same: which Singfiller variant corresponds to the product I have been injecting so far? This page classifies the best-known product lines by concentration, injection depth and the needles supplied. It does not replace the respective manufacturer's instructions for use.

How to compare fillers meaningfully

Brand names are of little help in a comparison, as each line uses its own numbering. Four specifications are more informative:

• Concentration in mg of hyaluronic acid per ml. Most cross-linked fillers are between 15 and 25 mg/ml.
• Cross-linking and gel structure. Almost all manufacturers cross-link with BDDE but give their process different names (Hylacross and Vycross for Juvéderm, CPM for Belotero, IPN-Like for Stylage). For Singfiller, the particle size describes how firm the gel is.
• Intended injection depth according to the manufacturer, from the superficial dermis to subcutaneous or supraperiosteal.
• Needles supplied. As a rule, the firmer the gel, the thicker the needle (more on this in the needle guide).

The lines at a glance

Information taken from instructions for use, manufacturer websites and specialist retailers, as of November 2026. Manufacturers occasionally change pack contents and needles; the instructions for use in the pack are authoritative. The right-hand column indicates a similar area of use, not that the products are equivalent.

The Singfiller range for comparison

All four variants contain 1 ml of BDDE-cross-linked hyaluronic acid in a sterile prefilled syringe, CE-certified as a Class III medical device. “Price from” is the unit price for 10 syringes or more, including 19% German VAT.

What matters when switching

Concentration alone says little about how a gel feels during injection. Two gels at 20 and 24 mg/ml can behave similarly if their cross-linking and particle size differ. When switching, it has proved useful to start with the Singfiller variant that matches your previous injection depth and then, based on your own impression, move one level finer or firmer. Practitioners who do a lot of lip work usually end up with V1 or V2. For chin, jawline and cheek, most users choose V3 or V4.
