I READ THAT PRODUCTS PACKED IN CLEAR BOTTLES LIKE THE GLYCOLIC 10 CLEANSER ALLOW LIGHT TO BREAK DOWN INGREDIENTS LIKE THE ANTIOXIDENTS. WON'T THE LIGHT AFFECT THE VITAMIN A, C, AND E IN THE CLEANSER? MY BATHROOM DOESN'T HAVE A WINDOW, BUT THE LIGHTS IN THERE ARE BRIGHT. I KNOW THE PRODUCTS ARE TESTED FOR EFFECTIVENESS AND I'M CURIOUS TO KNOW HOW LONG THE CLEANSER WILL BE EFFECTIVE ONCE IT'S OPENED. (ALSO, THE FAN IN MY BATHROOM KEEPS THE TEMPERATURE AT A CONSTANT LEVEL AND IT ISN'T HUMID B/C I LEAVE THE DOOR OPEN WHEN THE SHOWER IS RUNNING.)
