Usage Method for Salicylic Acid EZ Gel and Encapsulated Salicylic Acid

Based on the information provided:

For the Salicylic Acid EZ gel formulation you mentioned, it can be used as a leave-on treatment after waiting approximately 15 minutes for it to work, or you can choose to wash it off if you prefer a lighter feel on the skin.

If you use Encapsulated Salicylic Acid instead, it is generally gentler and does not require the 15-minute waiting period. Whether you need to wash it off depends on your skin's tolerance. If your skin tolerates it well, you can leave it on. If you experience irritation, it's recommended to wash it off after a while.

In summary, whether the salicylic acid gel needs to be washed off depends on the specific type of salicylic acid used and your individual skin's reaction and tolerance.
