Did salicylic acid pad damage my skin?

I used a 2% salicylic acid pad several times and it burned badly. Now the skin inbetween my eyebrows has a redder pigmentation, but it's been like this for a month. Have I burned my skin? Up close it looks like some small patches may have peeled, or burned off, from when I originally applied the pads, but a new fresh layer of skin doesn't seem to be emerging. The area has not burned since the original incident, nor is it itchy or painful. Will it heal, or will the redness eventually go away?
