Sweat, body odor and deodorant

You can find it at drugstores, convenience stores, supermarkets and online shops. Sticks, roll-ons and sprays are all available, though the range varies by store. Check the label first to see whether a product reduces sweat or manages odor. Travel sizes are also widely available.

In Korea, antiperspirants that reduce sweating itself are classified as quasi-drugs, while products that mask odor or absorb sweat are classified as cosmetics. Look for the word 의약외품 (quasi-drug) on the package to tell them apart, and choose according to your needs.

Antiperspirants are said to work best when applied to clean, dry skin before you start sweating. That is why many directions suggest applying them at night or after showering. Usage varies by product, so follow the instructions on the label.

Look for the word 의약외품 on the container or box. You can also search the product name on the Ministry of Food and Drug Safety's Drug Safety portal (의약품안전나라) to see whether it has been approved or notified. Be more careful with products bought directly from overseas, which may not have been reviewed under Korean standards.

Labels generally advise against using it on broken skin, on areas with eczema or dermatitis, and right after hair removal. If it stings, turns red or itches, wash it off and stop using it. If symptoms persist, see a dermatologist.

Studies show that a variant of the ABCC11 gene, linked to less underarm odor, is common among East Asian populations. Still, body odor varies widely with skin bacteria, diet and health, so it is not something to generalize by nationality.

Korean summers are often hot and humid, so many people wear breathable clothing, shower often and carry a handkerchief or wipes. Antiperspirants or deodorants are used as needed. If heat rash appears, keep the skin cool and dry. Light, quick-drying fabrics are popular for this reason.

Fresh sweat is mostly odorless. The smell develops when bacteria on the skin break down components of sweat. That is why regular washing and clean clothing are the basics. If your body odor changes suddenly or becomes much stronger, consider seeing a doctor.

If you sweat so much that it disrupts daily life, it may be hyperhidrosis, so consult a dermatologist. Causes and management differ from person to person and are best assessed by a doctor. Avoid self-medicating based on guesswork. A doctor can also suggest everyday ways to manage it.

Do not spray near your face or inhale it, and use it in a ventilated space. Aerosols can be dangerous near open flames. If you plan to fly with one, check the airline and airport rules on liquids and aerosols.

Sweat, skin oil and product residue can build up in fabric and discolor over time. Letting deodorant dry fully before dressing helps. Wash sweaty clothes soon rather than leaving them for days. Pre-treating stained areas before washing can also help.

Wash your feet daily and dry thoroughly, including between the toes. Rotate shoes so each pair can dry out, and choose socks that absorb sweat. If you notice itching or peeling skin, see a dermatologist. Taking out insoles now and then to air them also reduces odor.

In Korea you may remove your shoes at floor-seating restaurants, jjimjilbang or when visiting homes. Wearing clean socks and letting shoes dry out between wears helps a lot. Some people carry a spare pair of socks in their bag just in case.

Perfume can mask odor briefly, but mixed with sweat it may smell stronger. It works better to wash first, use deodorant, and then add a light scent. Subtle fragrance is often said to be preferred in Korea. Applying fragrance to clothing rather than sweaty skin is another option.

Many people use lightweight skincare and finish with oil-control products or powder. Blot sweat gently with oil-blotting paper or tissue instead of rubbing. Reapply sunscreen if sweat washes it away. Reapply sunscreen as needed if you wipe your face often.

Yes. Ingredients such as fragrance or alcohol can cause irritation or allergies in some people. Test a new product on a small area first. If redness or itching appears, stop using it, and see a dermatologist if it continues. Avoid using them right after hair removal or on broken skin.

Heat rash often happens when sweat cannot escape the skin, so keep cool and well ventilated. Avoid tight clothing and wipe away sweat often. For babies or severe cases, it is best to see a doctor. Light cotton clothing is often recommended.

Solid stick deodorants are usually easier to carry, while liquids, gels and sprays must follow cabin liquid rules. Aerosols may also be subject to airline-specific rules. Check the airport and airline guidance before you travel. Choosing a small travel size also makes packing easier.

Some say hair gives sweat and bacteria more places to linger, which may make odor more noticeable. Hair removal is a personal choice, though, and washing and drying well matter more. Avoid applying deodorant right after hair removal. Wait until the skin calms down after hair removal.

Diet or seasonal changes can alter body odor, but a sudden, major change can sometimes relate to health. If you are concerned, talk to a doctor. Avoid jumping to conclusions about the cause on your own. Mention any other symptoms you have when you see the doctor.
