Hi there, I love salicylic acid for lumpy bumpy skin on the top of my arms. I've seen strengths of 0.2% to 8%.
I want to put the very least amount of inflammation into my skin. But I still want the product to be efficacious.
Will the lower % still work ?
Thank you
Shelley
Salicylic acid is usually used in 2% concentration for facial skin, it is most likely efficacious in lower concentrations as well - I'd guess starting from 0.5% but I haven't seen research on this. Higher concentrations for face are usually used under supervision in medical peels.
The skin on your arms is thicker than on your face, and usually is less sensitive - so 2% might be a good starting strength for this area.
