Can hydrogen peroxide soften earwax?

Under normal circumstances, hydrogen peroxide can soften hard, lump-like earwax. However, it is not recommended for self-use if there is ear canal inflammation or severe earwax impaction. If in doubt, it is advisable to consult a healthcare professional beforehand. Detailed explanations are as follows:

If the earwax is hard and block-like, difficult to expel naturally, and there is no damage or inflammation in the ear canal, using an appropriate amount of medical-grade hydrogen peroxide (3% concentration) may help break down the oils and keratin in the earwax, gradually softening and loosening it so that it can be more easily expelled through actions such as chewing or speaking. Care should be taken during application to control the dosage and avoid excessive amounts flowing deep into the ear canal.

If there is inflammation, injury in the ear canal, or the earwax is deeply impacted, self-administering hydrogen peroxide may irritate damaged mucous membranes, worsening symptoms such as swelling, pain, or discomfort, and could even lead to spreading infection. Additionally, the bubbling action of hydrogen peroxide might push impacted earwax further inward, increasing the difficulty of removal. In such cases, professional medical assistance is required, and self-treatment with hydrogen peroxide should be avoided.

Prior to using hydrogen peroxide, ensure the condition of the ear canal is assessed; avoid contact with eyes or broken skin. If symptoms such as ear pain or hearing loss occur after use, discontinue immediately and seek medical attention. Earwax removal should prioritize gentle methods, as frequent use of hydrogen peroxide may disrupt the natural environment of the ear canal.
