Wax formation in ear is normal phenomenon and type of wax varies with genetics. Please visit an ENT, get your ears cleaned completely, and ask if there is any other finding in ears. if not, then nothing to worry.
Ear canal has self cleansing property and wax gets cleaned on its own without the knowledge of the person. If it accumulates in large amount, it needs cleaning by doctor/health care worker and once cleaned, it remains clean if you do not manipulate it much with ear buds. If there is some other problem like recurrent
fungal infection, needs to be examined by the ENT. Otherwise, keeping ears dry and not using oil or avoiding using ear buds help in long term. Regards
