I'm noticing that quite a few moisturizers (including the one advertised by acne.org - the one with licochalcone) that are targeted at acne or rosacea contain squalene as an ingredient. Why would they put this ingredient in their product when it has been shown that oxidized form of squalene (squalene peroxide) actually provokes acne formation? I'm hesitant to even use such products because of this. I mean how do we know the squalene is or will not oxidize on contact with the skin?
