Hyperhidrosis: You have axillary hyperhidrosis. If over the counter antiperspirants are not working, including Certain Dri, you should consider prescription based medication of higher % aluminum chloride. Remember to apply at night when you are not sweating. Another option is oral medication, but this can cause side effects. The yellow color is a reaction of your sweats and the antiperspirant.
