Most of the  jewelry that is on the YoniDaPunani website is Hypoallergenic. The "HOMEGIRLZ 4EVER COLLECTION" which was mentioned earlier is a collection of only hypoallergenic jewelry   I have very sensitive skin and so I make sure that I am able to wear the same materials that I send out. I spend COUNTLESS hours researching safe metals as well as building trusted relationships with suppliers to ensure you will always receive high quality material. If you have any questions about what may be safe for sensitive skin or just want to be sure please email the Customer Care Team at customercare@yonidapunani.com and they will let me know and I will get a hold of you directly to discuss some options.
