Introduction

When body odor is not obvious, occurring only slightly after exercise or in hot, humid environments, and there is no redness, itching, or skin damage in the underarm area, using antiperspirant can reduce sweat secretion, inhibit bacterial growth, and thus temporarily alleviate odor, making daily social interactions more comfortable. Choose a mild-formula antiperspirant and apply it correctly as directed to minimize skin irritation.

Generally, when body odor (bromhidrosis) is mild and the underarm skin is intact, antiperspirants can temporarily help alleviate odor. However, if the body odor is severe or the underarm skin has injuries or inflammation, antiperspirants may have limited effectiveness and are not recommended. If in doubt, it is advisable to consult a healthcare professional in advance. Detailed explanation is as follows:

When the odor is not obvious and only slightly occurs after exercise or in hot, humid conditions, and there are no issues such as redness, itching, or skin damage under the arms, using antiperspirants can reduce sweat secretion and inhibit bacterial growth, thereby temporarily reducing odor and making social interactions more comfortable. Choose a mild formulation antiperspirant and apply it correctly as instructed to minimize skin irritation.

If the odor is strong and remains noticeable even after regular cleansing, antiperspirants can only briefly mask or alleviate the odor but cannot fundamentally improve the condition. If there are skin injuries, folliculitis, or allergic reactions on the underarm skin, applying antiperspirants may irritate the damaged skin, worsen inflammation, or even cause pain and infection, thereby aggravating discomfort. In such cases, skin issues should be treated first or professional improvement solutions sought.

Before daily use of antiperspirants, ensure the underarm area is clean. If redness or a stinging sensation occurs after application, discontinue use immediately and wash off the product. If discomfort persists, seek medical attention promptly to avoid long-term irritation that may lead to skin problems.

In general, axillary bromhidrosis may be caused by genetic factors, excessive sweat secretion, local bacterial infection, endocrine disorders, dysfunction of apocrine sweat glands, and other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition through general treatment, medication, surgical treatment, or other methods under the guidance of a physician.

How Does Body Odor (Bromhidrosis) Develop?

During puberty, hormonal changes in the body lead to increased secretion of androgens, which stimulate the rapid development and enhanced secretory function of the axillary apocrine glands. This results in increased sweat production and altered sweat composition. The sweat is then broken down by bacteria, leading to the development of body odor. It is recommended to choose loose, breathable cotton clothing to prevent sweat accumulation in the armpits, and to use mild cleansing products to keep the underarm area clean.
