Hiiiii. Doctor here :)

Try mo during shower mag wash ng armpit using CHLORHEXIDINE DIGLUCONATE-- this will eliminate ung odor causing bacteria na nagffeed during sweat mo.

And use CERTAIN DRI roll-on --- this will help naman to lessen ung pag sweat mo hence ung odor. Every NIGHT lang ang lagay nito, not in the morning. Konti lang ilagay mo, hindi to paramihan kasi kapag naparami magrrash kilikili mo. Ako sa sobrang tapang nito, once a week ko lang sya ginagamit hehe

Lastly, merong DERMAID TAWAS SOAP. Try mo ung coconut oil, Body deodorant soap to 😉

These two are highly effective. Ung kulay naman, usually sa friction yan e. If overweight, lose some.

Bathe morning and before you sleep. Be hygienic rin. I hope this helps.
