Are you thinking about getting just a regular lobe piercing? I would think that there would be other options such as peroxide, but I don’t think you’ll be able to just walk into a Claire’s or Piercing Pagoda at the local mall to get it. As @augustlan suggests, I would ask your doctor’s office, or even a reputable tattoo parlor to see if they have alternatives. It will most likely be more expensive to have it done at a doctor’s office or tattoo parlor, though, so keep that in mind. Either way, I recommend stainless steel or gold earrings, especially if you have sensitive skin, because you may be allergic to the nickel in the other options.
Aftercare, however, is a whole different story. Rubbing alcohol, as @augustlan says, is not used for aftercare. Most piercing places will sell a saline cleaning solution that does not contain rubbing alcohol. I have used these cleaning solutions from several piercing places, and they have always been very gentle and work well. One that I really liked was H2Ocean Piercing Aftercare Spray. It’s a little more expensive than most cleaning solutions, but it is well worth it, in my opinion. I used it for my tragus piercing, which is an area of the ear that has very thick cartilage- it was extremely gentle and soothing, and my piercing healed perfectly.
