As we start thinking about the end of the rainy season in 2026, we are rapidly shifting from a season of damp, humid rain to a season of intense heat and strong ultraviolet rays.

Once the rainy season ends and summer truly begins, sweat and sebum secretion become more active, making it a time when skin problems such as clogged pores, acne, dullness, sunburn, and inner dryness tend to surface all at once.

This time, we'll clearly explain everything from the causes of summer-specific skin problems that you should reconsider now that the rainy season is over, to the correct summer skincare methods, and recommended skin care treatments that you can consult with a dermatologist.

1. Reasons why skin becomes more prone to irritation after the rainy season ends

Summer skin problems aren't caused by just one factor. Multiple negative factors, such as sweat, sebum, UV rays, and dryness from air conditioning, combine to rapidly disrupt skin condition.

1) Excessive secretion of sweat and sebum

As temperatures rise, the skin tends to produce more sweat and sebum to protect itself. This can make the skin's surface sticky, and if old sebum and dirt remain in the pores, it can lead to blackheads, clogged pores, and acne. However, washing your face too many times a day because you're concerned about oiliness can strip your skin of essential moisture, actually worsening dryness and skin irritation.

2) Rapid increase in ultraviolet radiation

Once the rainy season ends, sunny days increase, and UV radiation levels peak. UV rays not only cause sunburn, but also lead to blemishes, dullness, dryness, and "photoaging," which robs the skin of its elasticity, so consistent daily protection is essential. Particular care is needed for areas prone to sunburn, such as the cheeks, nose, forehead, neck, and the backs of the hands, where signs of aging tend to appear.

3) Inner drying using air conditioner (cooling)

In summer, we sweat outdoors, but when we go indoors, air conditioning tends to dry out our skin. If your skin feels oily on the surface but tight underneath, it's a sign that the balance of oil and moisture in your skin is disrupted (inner dryness). If left untreated, this condition can make enlarged pores, oiliness, and fine lines caused by dryness more noticeable.

4) Combined irritation caused by masks, makeup, and sweat

When masks and makeup are in close contact with the skin for extended periods while sweating, friction and humidity can make the skin extremely delicate. The areas around the nose, cheeks, and chin are particularly prone to clogged pores and redness. After returning home, it is essential to gently remove dirt with a cleanser and face wash, and immediately apply moisturizer.

 

2. The correct skincare methods after the rainy season ends

For summer skincare, the balance between "cleansing care," "protecting care," and "moisturizing care" is the most important thing.

1) Wash your face gently and never over-wash.

Even if you're concerned about sweat and sebum, scrubbing your face vigorously is a no-no. Aim for two washes a day, morning and evening. Lather your cleanser well and gently wash your face by rolling the foam over your skin. After washing, replenish moisture immediately with toner and lotion before your skin feels tight.

2) The basic rule for sunscreen is to apply it "every day + frequently."

After the rainy season ends, thorough sun protection is necessary even for short outings or on cloudy days. Don't just apply sunscreen in the morning and be done with it; ideally, reapply it every 2-3 hours on days when you sweat or spend a long time outdoors.

3) Even on sticky days, don't skip moisturizing.

In the summer, some people stop their skincare routine after just applying toner because their skin feels sticky. However, if your skin doesn't get enough moisture, it will produce even more sebum as a defense mechanism. Choose products with a non-greasy texture, such as a refreshing gel cream or a light lotion, to lock in moisture from within your skin.

4) Pore and exfoliation care should be done at a reasonable frequency.

This is a time of year when pores and blackheads are a common concern, but using scrubs or strong peels too frequently can damage the skin's barrier function. When incorporating exfoliation into your routine, aim for gentle care that suits your skin condition, such as once or twice a week.

 

3. Professional summer skin care consultations available at cosmetic dermatology clinics.

If self-care alone isn't enough to improve stubborn clogged pores, acne, blemishes, dullness, or dryness, then incorporating professional treatments at a cosmetic dermatology clinic is a smart option.

1) If you are concerned about pores, sebum, and shine

If you have oily skin and are concerned about rough pores, we recommend pore cleansing treatments such as **HydraFacial (Aqua Peel)**, which cleanses deep into the pores without stressing the skin. This is a better way to achieve clear pores without damaging your skin than forcibly squeezing out blackheads at home.

2) If you are suffering from recurring adult acne or skin problems

If you notice a sudden increase in acne after the rainy season ends, the quickest solution is to have a professional examine the balance of sebum and acne bacteria, as well as your skincare routine. If you have ongoing inflammation or redness, consult a dermatologist as soon as possible to consider appropriate treatment or peeling.

3) If you want to prevent and improve blemishes and dullness

Summer, when UV rays are strongest, is the perfect time for whitening care to prevent future blemishes. By using sunscreen as a base every day, and combining it with **"Pico Toning"** to even out skin tone, and whitening/brightening treatments to support transparency, you can more easily maintain clear, radiant skin even in summer.

4) For summer dryness (inner dryness) and lack of firmness

For those who feel their skin has lost its radiance and firmness due to air conditioning or UV damage, skincare products such as **"skin boosters" (including hydro-injections)** that deliver nutrients and moisture directly to the inside of the skin are also popular. By moisturizing from within, these products can also help suppress excessive sebum secretion.

4. Q&A

Q1. Why do acne cases tend to increase sharply after the rainy season ends?

A. This is because rising temperatures increase sebum and sweat production, making it easier for old dead skin cells and dirt to clog pores. Additionally, dryness caused by air conditioning and a weakened skin barrier function due to UV rays can also trigger acne.

Q2. My skin gets sticky in the summer, so is it okay if I don't apply lotion or cream?

A. Even in summer, you need to seal in moisture with oil (lotion or cream). When you're in an air-conditioned environment, your skin's moisture evaporates rapidly, leading to inner dryness. If you don't like sticky textures, it's recommended to choose a refreshing gel type or a moisturizing cream.

Q3. What skincare routine should I focus on most after the rainy season ends?

A. Above all, it's "UV protection (UV care)." UV damage from summer exposure manifests as blemishes, sagging, and skin aging from autumn onward. Make sunscreen a part of your daily routine.

Q4. Can I receive laser treatments and other procedures at a cosmetic dermatology clinic even in the summer?

A. Yes, you can receive treatment. However, depending on the treatment, thorough sun protection (UV protection) before and after the treatment is essential. It is best to first discuss your skin condition and lifestyle during a consultation to determine the most suitable treatment for you.
