More questions about GOURI?
What does liquid PCL mean?
PCL stands for polycaprolactone, a polymer ingredient. GOURI uses DEXLEVO’s solubilization technology. The formulation’s liquid form and your individual suitability for treatment are separate considerations.
How is it related to collagen?
DEXLEVO describes CESABP as technology that induces tissue responses associated with collagen synthesis. This mechanism does not imply identical changes or duration for everyone.
Is the same method used across the whole face?
The officially approved purpose in Korea is temporary improvement of fine lines at the outer corners of adults’ eyes. Discuss treatment areas and scope with your clinician.
How are the number and spacing of sessions decided?
Your skin condition, prior treatments and response are considered together. Discuss an individual plan and follow-up timing rather than assuming a fixed number of sessions.
What reactions may occur?
Bruising, swelling, redness, tenderness and itching may occur; inflammation, nodules and hypersensitivity reactions have also been reported. Contact your treating clinic if discomfort is severe or persistent.
What if I use medication or have other treatments?
