Hey R & P! Got another question for you:
How well does betaine salicylate work compared to salicylic acid? Are the two comparable in regards to preventing blackheads and controlling sebum? More specifically can Cosrx’s ‘BHA Blackhead Power Liquid‘ (4 % betaine salicylate, pH 4.0) in theory work just as well as Paula’s Choice ‘BHA‘ (2 % salicylic acid, pH 3.2-3.
?Great question! I’ve looked into this and I plan to discuss it on our podcast. Is there any chance you’d be interested in recording an audio version of your question for the show? If you are, all you have to do is record your voice on your smart phone or computer and email it to us at thebeautybrains@gmail.com.
