I completely understand your concern and I hope I am able to help you for the same.
You seem to have developed an allergic reaction
You need to apply a mild topical steroid
over the lips twice a day for 2-3 days.
Keep using a moisturizer regularly.
Do not use any other lipsticks for some days.
Use a sunscreen over the lips also when going out
I am sure this will help you,
Dr Geetika Paul.
