How long should I wait before deciding if salicylic acid is working or if I should switch to a different ingredient?
Healing blemishes takes time, so give your new regimen about a month before deciding whether or not it’s actually working. Additionally, it might be the particular product that isn’t working rather than the active ingredient. Try increasing the concentration of salicylic acid if your blemishes aren’t clearing up (or, for sensitivity, decreasing the concentration), rather than jumping to a new ingredient immediately. Also, you can make an appointment with your dermatologist to discuss the best acne product for you.
