I am in need of a serious advice.

I've applied 25% mandlic acid peel on my face as a regular routine, however some of the acid accidentally dripped into my mouth and touched my inner lips. It took me couple seconds to notice the sensation, and so I washed it off RIGHT away. However, it caused frosting in my inner lips as shown in the picture, and I'm quite worried. I know this is a very unusual case and it's my very own faults, so I really need advice on whether this would resolve on it's own or if I caused permanent damage to my lips.

Please help! Any feedback would be appreciated!
