Hello.

I am Kim Jin-hyun, Chief Director of UNNI Clinic Mokdong.

“Do I really need to remove underarm hair?”

Many men say this when they first start considering hair removal.

In fact, hair removal is common for women, but men have only recently begun to actively use it.

However, I do not see hair removal as a procedure done solely for cosmetic reasons.

I think it is a procedure that helps relieve various inconveniences, such as sweat odor in summer, skin discoloration, and an uncomfortable sensation.

Today, I will explain why men’s underarm hair removal can be connected not just to appearance, but also to hygiene management and other areas.

Men’s Underarm Hair Removal

Problems with repeated shaving

In the past, men often did not pay much attention to shaving or removing underarm hair.

But these days, more people are considering shaving or hair removal for a cleaner appearance.

However, men’s underarm hair is usually relatively thick and dense.

If you keep shaving it with a razor, the chances increase of repeated skin injuries, discoloration, and ingrown hairs.

Because male body hair tends to have thick roots, shaving it can even leave a more bothersome bumpy texture.

This happens because when hair is cut with a razor, the cross-section of the hair is left blunt.

Hair that grows out smoothly may taper diagonally and not be very noticeable,

but hair cut by shaving leaves a round, blunt cross-section, which irritates the skin more and gives a rough feeling.

Underarm laser hair removal

“Then can laser hair removal remove everything at once?”

People often think laser hair removal is a procedure that burns all the hair away, but in reality, that is not the case.

Laser hair removal works by suppressing hair growth or making the hair finer, depending on the hair growth cycle.

A laser of a specific wavelength is absorbed by melanin pigment, delivers heat to the hair root area, and thermally denatures the follicular stem cells that drive hair growth.

As this process is repeated, the hair gradually becomes finer and lighter, growth slows down, and eventually the growth itself decreases.

In other words, it is not possible to remove all the hair at once, but if the procedure is performed over several sessions according to the cycle, you can expect a natural and neat result.

The number of sessions varies depending on the thickness of the hair, skin color, and hair density, but generally 4 to 6 sessions or more are considered standard.

Can it also help with summer hygiene management?

Surprisingly, many people are also amazed by the various changes they experience after hair removal.

In fact, hair removal can help manage odor, sweat, skin friction, and other issues.

Underarm hair holds sweat, and bacteria grow in it, causing a distinctive odor.

But when hair is reduced through hair removal, bacterial growth around the sweat glands also decreases, which helps reduce odor.

Also, sweat dries more easily, and hair-removed skin can absorb products like deodorant more effectively.

Therefore, it has a positive effect on summer hygiene management as well.

Above all, you are freed from repeated shaving irritation, and in some cases you may observe improvements in discoloration, skin tone, and irritation.

So I can say that laser hair removal is not simply about removing hair, but a useful procedure that can manage many things at once.

Many men still tend to think of underarm hair removal only as a cosmetic choice,

but I would like to say that it is a practical option that can reduce ongoing discomfort, create a hygienic environment, and help care for skin health as well.

Of course, not everyone needs hair removal, but if you are experiencing discomfort due to repeated shaving, odor, discoloration, or skin trouble, laser hair removal can be a worthwhile option.^^

This has been Kim Jin-hyun, Chief Director of UNNI Clinic Mokdong.

Thank you.
