I have used a 10% glycolic acid cream and I experienced some stinging, but the form in a wash should be much less concentration. I have also used a salicylic acid moisturizer, and the only side effect seen alot in people seems to be dryness. I think that you could definitely use these products together, as the glycolic acid isn't left on the skin and shouldn't be a problem, and the salicylic acid probably isn't a high concentration as it is in a moisturizer. To be sure, you could try them and notice how your skin feels.
