You may be experiencing some initial irritation from inserting a new pair of earrings. This is normal and is a result of tissue damage around the piercing site. This should go away after a few hours. We highly recommend giving your piercings a few hours or days to adjust to our earrings. We always recommend using Aquaphor, Vaseline, or a similar lubricant around the piercing site and on the earring post when inserting a pair of earrings. This will help minimize tissue damage and irritation. We also suggest doing a saline or salt water rinse once per day around the piercing site to aid in healing. It is extremely rare to be allergic to pure titanium, but if the initial irritation gets increasingly worse over time or your ear lobes start to swell, then you may be experiencing an allergic reaction. For more information on healing your piercings, we put together this Step by Step Guide. Please contact us at info@tinilux.com with additional questions.
