Cycle your deodorant/antiperspirant. If you find something that works for you, sometimes nangyayari yung after a few months/weeks e parang di na sya effective. Nangyayari sa kin to. Gawin mo, try some other brand. Then after a few weeks, balik ulit sa dating brand. Pag minsan na-iimmune din daw mga sweat glands e. Nung una di ako naniwala, pero nung ginawa ko, totoo nga, mas effective kung i-cycle yung deo. Ako nga halos everyday I use a different brand. 2-3 days straight na yung maximum na di ako magpapalit ng brand. And this practice really works for me.
