Help me get salicylic acid

there are plenty of face washing products that have salicylic acid in them.

Considering that lactic and salicylic have very similar properties I don't think you can do it with household equipment.
In fact the only way I can think on the spot is basic hydrolysis of aspirin then separation with ion exchange LC with acidic solution as mobile phase.
Possibly there may be more extravagant solutions like using lipase in synthesis with a fatty acid as nucleophile, assuming we can use aspirin as a substrate.

Extract it from trees in genus Salix, willows.

Well, I should have made it clear. I don't mind getting a bit of lactic acid on my end product. I just want to get it out of the damn thing.

Flexible colloidon sounds cool, maybe you can aggregate it by messing with the pH or temperature, careful though as both sa and lactic acid will change solubility. Maybe put it in a vat of water, get it to aggregate, and scoop it from the top like rendering fat
Once you get it down to crystals of lactic acid and salicylic acid I'd carefully melt the lactic acid away
