In the summer, you often hear the term "heat index (WBGT)" in the news and weather forecasts.

The heat index is an index used to prevent heatstroke, based not only on temperature but also on humidity, solar radiation, and radiant heat. The Ministry of the Environment also explains the heat index as "an index that focuses on the exchange of heat between the human body and the outside air."

In fact, on days with a high heat index, not only is it difficult to manage your physical condition, but your skin is also more susceptible to stress. Increased sweat and sebum secretion, combined with exposure to strong ultraviolet rays, can easily lead to skin problems such as clogged pores, acne, redness, flushing, dryness, and inner dryness.

This time, we'll introduce common summer skin problems that occur on days with a high heat index, the correct skincare methods to improve your skin condition, and treatments you can consult at a cosmetic dermatology clinic.

1. What is the Wet Bulb Globe Temperature (WBGT) index?

The Wet Bulb Globe Temperature (WBGT) is an international indicator used to prevent heatstroke.

Because factors such as humidity, sunlight, and reflection from the ground and buildings all play a role, the heat index can be higher on days with high humidity or strong sunlight, even if the temperature is the same.

In other words, on days with a high heat index, not only is the body more susceptible to strain, but the skin is also more vulnerable to the effects of sweat, sebum, UV rays, and dryness.

In particular, Japanese summers tend to be hot and humid, making it a season when skin conditions are easily disrupted, with the surface feeling sticky while the inside remains dry.

 

2. Why skin problems are more likely to occur on days with a high heat index.

1) Pore problems caused by increased sweat and sebum

On days with a high heat index, body temperature tends to rise, and you sweat more easily.
At the same time, sebum secretion tends to increase, and if sweat and sebum remain on the skin's surface for a long time, they mix with old dead skin cells and dirt, making clogged pores, acne, and makeup breakdown more likely.

The areas around the nose, forehead, and chin are particularly prone to oiliness, so careful care is essential during the summer.

 

2) Skin damage caused by ultraviolet rays

On hot days, we tend to spend more time outdoors, which increases our exposure to ultraviolet rays.

Ultraviolet rays can lead not only to sunburn, but also to skin aging such as blemishes, dullness, chronic dryness, wrinkles, and sagging.

Therefore, on days with a high heat index, it is important to be mindful of UV protection in addition to taking precautions against heatstroke.

 

3) Inner drying using air conditioning

Even if you sweat outside, indoors, air conditioning can easily strip your skin of moisture.

If your skin feels oily and sticky on the surface but dry underneath, you may have a condition called "inner dryness."

If inner dryness is left untreated, the sebum balance will be disrupted, making you more prone to concerns such as enlarged pores, oiliness, and fine lines caused by dryness.

 

4) Redness and flushing due to heat buildup

When your skin gets hot from strong sunlight or the heat outdoors, you may experience redness or flushing.

When your skin feels warm, it means your skin is in a state where it is more sensitive.
Therefore, it is recommended to avoid harsh skincare products and excessive self-peeling, and instead incorporate skincare that focuses on moisturizing and soothing.

3. The right summer skincare methods to get through hot days

1) Do not rub sweat; gently pat it away.

Leaving sweat on your skin can easily lead to stickiness and skin irritation.

When wiping away sweat, use a clean towel or tissue and gently pat it on rather than rubbing.

Friction can lead to redness and irritation, so it's important to care for your skin gently.

 

2) Wash your face gently, and don't over-wash.

It's not recommended to use facial cleanser multiple times a day just because you're concerned about oily or greasy skin.

Washing your face too often can strip your skin of essential moisture, leading to dryness and skin irritation.

As a basic rule, wash your face in the morning and evening. Lather your facial cleanser well and wash gently, enveloping your face in the foam.

3) Reapply sunscreen frequently.

On days with a high heat index, sunscreen is more likely to wash off due to sweat and sebum.

Instead of just applying it in the morning, it's recommended to reapply it every 2-3 hours if you're spending a long time outdoors.

The cheeks, nose, forehead, neck, and backs of the hands are particularly susceptible to UV exposure, so be sure to take care of these areas.

4) Continue moisturizing even on sticky days.

In the summer, some people find lotions and creams too sticky and end their skincare routine with just toner.

However, skin tends to dry out easily due to the effects of air conditioning and ultraviolet rays.
Insufficient moisturizing can actually make sebum more noticeable and disrupt the skin's barrier function.

Choose a refreshing gel-type product or a light, non-greasy lotion to balance the moisture and oil levels in your skin.

 

4. Summer skin care that you can consult about at a cosmetic dermatology clinic

If you're still concerned about rough pores, acne, redness, or dullness despite self-care, one option is to consult a dermatologist to have your skin condition checked and receive professional treatment.

 

1) If you are concerned about blackheads and oily shine in your pores

If you are concerned about excessive sebum or clogged pores, you may consider pore-cleansing treatments or peeling treatments to remove unwanted dead skin cells, depending on your skin condition.

For example, pore cleansing treatments such as HydraFacial and Aqua Peel are among the treatments that people concerned about clogged pores and excess sebum can easily consult about.

However, if your skin is very dry or red, it's important to choose a product that suits your skin condition to avoid excessive irritation.

 

2) If you are concerned about recurring adult acne or skin problems

If you tend to get acne due to sweat and humidity, it's important to review your skincare routine and lifestyle habits as well.

If you have inflamed acne or painful redness, it's best not to try to pop it yourself, but to consult a dermatologist as soon as possible.

At a cosmetic dermatology clinic, you can consult about acne treatment, soothing care, peeling, and other treatments tailored to your skin condition.

 

3) If you are concerned about blemishes, dullness, or sunburnt skin

If you are concerned about dullness or uneven skin tone after sun exposure, we may consider toning treatments or brightening care tailored to your skin condition.

We offer a range of options to suit your skin concerns, including laser treatments such as pico toning and infusion treatments incorporating brightening ingredients.

However, since summer is a season when you are more likely to be exposed to ultraviolet rays, sun protection before and after treatment is especially important.

 

5. Q&A

Q1. Is it true that skin is more prone to irritation on days with a high heat index (WBGT)?

On days with a high heat index, factors such as sweat, sebum, UV rays, and dryness caused by air conditioning tend to combine, making it easier for skin condition to become unbalanced.

If you are particularly concerned about pores, acne, redness, flushing, or inner dryness, it is recommended to be more mindful of thorough skincare than usual.

 

Q2. In the summer, I want to feel refreshed, so is it okay to wash my face multiple times with cold water?

Washing your face repeatedly with facial cleanser can strip away essential oils and moisture from your skin.

Use a facial cleanser in the morning and evening as a general rule, and gently blot away sweat and shine during the day with a clean towel or tissue.

For those with dry skin, it's important to thoroughly moisturize after washing your face.

 

Q3. What skincare routine should you be most mindful of on a day with a high heat index?

The three most important things are sun protection, sweat and sebum control, and moisturizing.

Remember to reapply sunscreen frequently, gently wipe away sweat, and continue moisturizing to prevent dryness caused by air conditioning.

On days with a high heat index, it's important to pay attention not only to preventing heatstroke but also to minimizing the strain on your skin.

Summer is a season when skin problems such as enlarged pores, acne, redness, and dullness tend to occur due to a combination of factors including sweat, sebum, UV rays, and inner dryness caused by air conditioning.

While maintaining good skin condition with daily home care, if you have concerns about pores, acne, or dullness that can't be addressed by self-care alone, consult a dermatologist for treatment tailored to your skin condition.
