I don't understand why you'd have to wean off Proactive. What would happen if you just stopped using it? If your skin breaks out again I would think you'd want to go back to using proactive. If it doesn't break out again then try something else.
I just don't see skin care products as something to have to wean off of. If they're working why stop? Unless you want to see if your skin doesn't need the product anymore. Then stop and see what happens.
