Choosing a treatment

Hyaluronic acid fillers add volume, while collagen stimulators support more gradual changes. We assess your facial structure and concerns before recommending either approach or a combination.

Ask our team

They work differently. Hyaluronic acid fillers add volume directly, while collagen stimulators encourage gradual collagen production. Some products have both effects.

Hyaluronic acid fillers can be treated with a dissolving enzyme when appropriate. Collagen stimulators cannot be dissolved in the same way. Discuss the product and its risks before treatment.
