Gudi hair removal for your underarms

If you want to keep them neat

When wearing sleeveless or short-sleeved clothing in summer, or when you need to wear a swimsuit, one of the areas that tends to draw attention first is the area beneath the arms.

Managing it with shaving or waxing every time can be bothersome, and many people worry that the hair quickly grows back even after treatment. Since this is a highly visible area, you may especially want to keep it looking neat.

These days, more people are using laser-based methods to maintain smooth skin for longer. Today, we will take a step-by-step look at how this method works and what you should know.

How does it work?

This method uses light that reacts to the dark pigment in the hair to deliver energy down to the roots.

When the light encounters the pigment, it is converted into heat, weakening the hair follicles and roots. With repeated treatments, you can expect the amount and thickness of newly growing hair to gradually decrease.

These days, treatments are often performed without contact, so the device does not directly touch the skin, making the process more hygienic. Rapid cooling systems are also used, greatly reducing stinging and irritation.

What treatment interval is appropriate?

Although it varies from person to person, it is generally recommended to wait about 4 to 6 weeks between treatments. This is because several sessions aligned with the hair growth cycle are needed for the treatment to work effectively down to the roots.

Because the thickness and amount of underarm hair differ from person to person, some may notice a difference after about 7–8 sessions, while others may need consistent treatment 10 or more times to approach their desired results.

Since individual results vary, it is a good idea to assess your condition after the first few sessions and plan how many more treatments you may need.

Maintaining an appropriate interval is important, as scheduling treatments too close together or too far apart may cause changes to appear more slowly.

Who is it suitable for?

This type of care is suitable for both men and women. In particular, because the underarm area tends to sweat a lot, repeated shaving can easily cause stinging or redness, while frequent waxing can make the skin more sensitive.

Because the laser method works from the roots, it can help reduce these inconveniences. It may also be helpful for people who frequently wear sleeveless or short-sleeved clothing, enjoy swimming or exercising, or often wear clothes that reveal their body lines.

In addition, when combined with care such as body pigmentation toning, it can help even out the overall tone, so it may be worth considering for those who want a cleaner and smoother appearance.

Things to take care of before treatment

It is a good idea to shave 1–2 days before treatment. If the hair is too long, the light may not be delivered properly to the roots.

If there is inflammation or a skin condition in the underarm area, it is best to wait until the condition improves before receiving treatment. Avoid tanning before and after treatment, and apply sunscreen thoroughly when going outside.

Caution is needed because extensive sun exposure when the skin is sensitive to light may cause pigmentation. Although the underarm area is often covered by clothing, it still requires careful care.

Things to take care of after treatment

After treatment, the remaining hairs will naturally shed over the course of 1–2 weeks. Do not forcibly pull them out or scratch them off with your hands.

If you irritate the area while the roots have not yet separated, it may become red or sting, so it is best to leave it alone. Also, avoid tight clothing and wear loose-fitting garments to reduce irritation to the underarm area.

Apply plenty of moisturizing lotion to prevent dryness. Since the area may become slightly red or feel warm on the day of treatment, cooling it with an ice pack or similar item may help you stay comfortable.

This usually lasts for about 2–3 days before naturally subsiding, so there is generally no need to worry. Please also note that abstaining from alcohol and smoking can help with recovery.
