I read somewhere that, once opened, benzoyl peroxide can start losing its effectiveness from the 3rd month. Kindly educate me on the validity of that statement. And when exactly should I toss the bottle and get a new one. And how I can maintain it's effectiveness once opened. Some say that putting it in the fridge helps. 
Thank you.

Hi Amina, 


Although the Acne.org Treatment does not expire, we do recommend that you use the product within 6 months upon opening it. As long as you keep the bottle in a dry, cool place, it should still be effective after a long while.
