I had an allergic reaction to 'Redensity 2' filler in my under eye hollow. Are there any other fillers I can try?

Hi @jarvo516! There are different options including Belotero and Restylane. I recommend seeking treatments from expert injectors who have the skill and experience to precisely inject fillers into treatment areas and avoid risks and complications. Best of luck, Dr. Nima!

Belotero and Restylane are good options for under eye filling. See following video and link. Technique and amount of filler injected matter too.

Redensity 2 is commonly used for the tear trough region.  An alternative filler for this area would be Juvederm Volbella.  

Thank you for your question. There are other brands of dermal fillers that are also suitable for tear troughs and will give excellent results. I recommend seeing an allergist about your previous reaction to dermal filler before you try another hyaluronic acid product. Best of luck,
