hey guys, so I've been using a lip balm since the start of this year and everything seems great about the product until recently. I realised that my lips were more dry even with the use of lip balm and my lips seem to be in a bad shape. I began to develop really dry skin on my lips especially the upper lip, dry flaky skin and it's hard and pain to the touch. There are also small bumps, ulcer-like on my lip. I've since stopped using it but the symptoms doesn't seem to be going away. Has anyone experience this before? Like being allergic to lip products? And should I be seeing a doctor, since I'm not sure if it's serious? Thank you!
