Applied 27.5% Salicylic Acid Wart Remover on Face Which Caused Dark Spots. What Do You Recommend? (photo)

Yes, I am extremely embarrassed I ever thought this would be a good idea! I did this yesterday, left it for a couple of hours, scraped it off and saw the spots. There is no pain or burning sensation, just those unsightly dark spots right where I applied the salicylic acid. I applied lanolin to calm the skin and I'm leaving it alone. I know it'll take time to get rid of these spots, but how long? Anything else I should do? I am too embarrassed to consult a doctor personally.
