Since much of what we put on our skin gets absorbed into our bloodstream, I was wondering if anyone knows if topical salicylic acid can cause irritation of the stomach lining? Or if anyone has experienced such a reaction?

I ask this because we know salicylates like Aspirin cause this effect when ingested. I do not know if the effect is due to the direct interaction with chemical and the stomach or a secondary effect due to their action on some inflammatory pathway (similarly like with other NSAIDs such as Ibuprofen)

So can washing your face every day twice a day with 2% salicylic acid wash have the same effect?
