Hi doctor. I want to tell you that the last 6 weeks. I went to take the acne medicine called Tetracycline at the nearby clinic. At first I only take 1 capsule medication as advised by the doctor. On the next day. My lips began to be felt as hot, burning and swelling. I decided to stop taking the acne medication because I already know the side effects will cause burning lips. So I immediately put on my lips with sea cucumber oil to reduce pain. At the same time. I also use branded products Sebamed. I only use cleansing toner, cleansing bar soap, care gel and APT gel to treat my acne. I've been using this product for 1 month and it seems effective nd no side effects on me. But the weird thing is, after 3 days. I began to feel my mouth like a hot, stinging and burning. I was very confused at the moment. Am I allergic to Sebamed products or the effects of drugs called Tetracycline? Or the side effects of these drugs are still inside my body? At this time. When my lips feel sting and heat. I will use sea cucumber oil to soothe him. I hope doctors can give opinions and advice. Thank you.
