Since it is the summer season, many people are inquiring about underarm hair removal.

However, it is true that various questions come to mind before actually beginning treatment.

So today, I will explain why underarm hair removal needs to be performed multiple times, which equipment may be suitable, and the pre- and post-treatment care points that determine satisfaction.^^

If you have been hesitating about whether to get Hongdae underarm hair removal, please pay attention.

Why does it need to be done multiple times?

Hair growth cycle

We often receive questions such as, "Why isn't laser hair removal finished in just one session?"

The reason, put simply, is that all the hair on our bodies does not grow at the same rate.

Some hairs are actively growing, some have stopped growing, and others are preparing to shed.

Among these stages of the hair growth cycle, laser hair removal is known to work effectively on hairs in the "anagen," or growth phase.

This is because hairs in the growth phase are well connected to the hair follicles and contain abundant melanin pigment.

We have previously written a column about how laser hair removal works, so you may find it helpful to refer to it.^^

[How does laser hair removal work?]

The issue is that not all hairs are in the growth phase at the time of treatment.

How laser hair removal works

A single laser treatment works effectively on hairs that are in the growth phase at that time, but hairs in the resting or regression phase may not be affected sufficiently.

Therefore, when hairs in the resting phase later enter the growth phase, the next treatment is performed to target them.

Although this varies depending on the individual's hair density, hair texture, and skin condition, it is generally recommended that treatment be performed about 5 to 10 times at intervals of approximately 4 to 6 weeks.

In general, as the number of sessions increases, you can expect the amount of hair to decrease, while the remaining hairs gradually become finer.

Which equipment should be used?

Underarm hair

Underarm hair is relatively thick and dark compared with hair in other areas of the body, and the underarms are also one of the areas people shave frequently.

Repeated shaving does not simply cut the hair; it also causes continuous irritation to the skin.

During this process, folliculitis may occur, or hyperpigmentation may develop, making the skin appear darker.

For this reason, many people consider underarm hair removal not only to reduce hair, but also to reduce the repeated irritation caused by shaving.

Hair follicle

Among the various laser hair removal devices, it is important to check the available wavelength ranges when receiving underarm hair removal.

This is because the location of the hair follicles varies from person to person, so having multiple wavelength ranges allows treatment to be tailored to the condition of the skin.

One device with these characteristics is Accento.

Accento

Accento is characterized by its ability to use two wavelengths: 755 nm and 1064 nm.

In other words, an appropriate wavelength can be selected based on the individual's skin condition, hair thickness, and skin tone.

  1. 755 nm laser

The 755 nm wavelength has a relatively high absorption rate for melanin pigment.

It can therefore work efficiently on thick, dark hair such as underarm hair, and is often used in the early stages of treatment when the hair is thick and dense.

  1. 1064 nm laser

Underarm hair

The 1064 nm wavelength can reach deeper areas.

It may therefore be used when the skin tone is relatively dark, when hyperpigmentation is present, or when deeper hair follicles need to be taken into consideration.

Because Accento can use both wavelengths, treatment can be approached more flexibly according to the current condition of the hair and skin.

Side effects such as redness, a burning sensation, and dry skin may occur after treatment.

How should you care for the area before and after treatment?

Even when the same equipment is used for the same number of sessions, results may vary.

One reason is pre- and post-treatment care.

With laser hair removal, not only the day of treatment but also how you care for your skin before and after treatment can have a significant effect on satisfaction.

Here are the care points we frequently recommend.^^

  1. Shave before treatment

Shaving before treatment

The laser is intended to target the hair follicle rather than hair that has grown long above the skin.

If the hair has grown long, the laser energy may be absorbed first by the hair on the skin's surface, causing unnecessary heat or irritation.

For this reason, we generally recommend shaving about one day before treatment and visiting the clinic afterward.

  1. Avoid waxing or tweezing

Avoid waxing whenever possible

Laser hair removal works by delivering energy to the hair follicle along the melanin in the hair.

However, if the hair is pulled out with waxing or tweezers, the hair follicle that the laser is meant to target is no longer present.

As a result, the hair removal effect may be reduced, so it is best to manage the area only by shaving during the treatment period.

  1. Pay attention to soothing and moisturizing

Soothing and moisturizing

After laser treatment, the skin may temporarily become dry or sensitive.

Therefore, using a gentle moisturizer to soothe the skin and maintaining sufficient moisture can be helpful.
