You will be able to get them wet because you must clean the area regularly. BUT you must avoid getting the area wet for prolonged periods of time. This will cause the scabs to get soggy and lift off which will increase the chance of scarring and loss of pigment. When you get them wet, you must pat them dry immediately to avoid complications and undesired results such as patchiness, scar tissue, and uneven pigment.
You must avoid sweating in that area for at least 10 days. Salt draws out pigment and you will be left with undesirable results.
