Sometimes I see anti-acne products with willow bark extract instead of salicylic acid. Do they work the same way, or what is the difference between these two materials in terms of effectiveness?
I think you should go for the synthetic made salicylic peels, cleansers with lower concentrations of either of these ingredients seem to be ineffective to me. I would just use Cetaphil and get a peel. Waiting for the BB to chime in on why they are marketed as the same thing.
salicylic acid is derived/comes from willow bark. so while theyre pretty much the same thing salicylic acid is probably more concentrated and effective, hope that helped even a little :)
