Skin Care Information: The Secret to Tackling Sun Exposure and Pores All at Once This Summer

Skin care information,

The secret to tackling everything from UV rays to pores

at once this summer!

Hello. This is Jamsil Gounsesang Dermatology!

When summer begins, there are times when you suddenly

sigh in front of the mirror.

“Yesterday it was fine, so why does my face look this

greasy today?” “Why have my pores gotten so much

larger again—where did my smooth, eraser-like skin go?” In the humid discomfort that you couldn’t feel during the

cool spring days, your skin feels it too: even sunscreen

can feel sticky, and the moisturizing cream you applied

yesterday can seem to dry out in just one day.

In particular, makeup settles quickly, and even a small

blemish stands out because of waste buildup inside the

pores, making you afraid to look in the mirror every

morning.

You are not the only one dealing with these concerns. But slathering on skin care products indiscriminately only

makes the skin more sensitive. That is why you need a

more systematic and scientific summer skin care strategy

that you can start right away.

Through this post, we will explain step by step how to

restore skin worn out by heat, UV rays, sweat, sand, and

chlorine to a healthy state ‘all at once.’ If you are nodding

along and thinking, “My skin gets so tired every summer,”

the seven steps below will definitely be helpful.

The scientific reasons why skin becomes sensitive in summer

In summer, ultraviolet rays become strongest of the year

(UV Index 8~10: World Meteorological Organization), and

UVA, which penetrates deep into the dermis, destroys the

structures of collagen and elastin. At the same time, UVB

damages the epidermis, causing sunburn and pigmentation

(World Health Organization, WHO).

In addition, in hot and humid environments, sweat and sebum

are secreted excessively, waste accumulates inside pores,

and the likelihood of inflammatory acne increases. Salt and

chlorine contained in seawater and pool water dry out the

skin texture, accelerating moisture loss, and friction can

cause dead skin buildup and folliculitis.

The right cleansing method without irritation

To improve summer skin troubles, irritation must be

minimized starting from the cleansing step.

When washing your face, using lukewarm water (30~35°C)

helps sebum and waste in the pores dissolve gently without

over-drying the skin surface. Use a light water-based foam

cleanser or gel cleanser for double cleansing, but avoid hot

water and oil cleansers with strong cleansing power, as they

can disrupt the sebum balance and instead promote excess

sebum production.

It is also recommended to use a chemical exfoliant

containing AHA (alpha hydroxy acid) or BHA (beta hydroxy

acid) 1~2 times a week. These ingredients dissolve dead

skin cells, gently remove the stratum corneum that blocks

pores, and help relieve non-inflammatory acne.

Sun protection completed with 'SPF 30~50, PA+++'

When choosing a sunscreen, you must understand the

meaning of the SPF and PA ratings accurately.

• SPF 30: Blocks about 97% of UVB (AAD recommendation).

• SPF 50: Blocks about 98% of UVB.

For outdoor activities, SPF 50 is recommended, but as the

SPF value increases, the risk of skin irritation also rises, so

for ordinary outings, it is reasonable to choose within

SPF 30~50 (Skin Safety Research Institute).

• PA+++: According to the Japanese JIS standard, this

corresponds to “high” among UVA protection indicators,

and effectively suppresses collagen breakdown from

everyday UVA exposure.

The usage method is as follows.

1. 20 minutes before going out

: Sunscreen needs at least 20 minutes for the ingredients to

be absorbed into the skin and for the chemical and physical

filters to fully form.

2. Reapply every 2~3 hours

: Sweat, sebum, and water activities can disturb the

protection layer, so it should be reapplied every 2~3 hours.

3. Amount to apply

: About 1/4 teaspoon (approximately 1.2 mL) is the proper

amount for the entire face, and you should carefully spread

it over easily forgotten areas such as behind the ears, the

neck, and the backs of the hands.

4. Skin procedures that help in summer

A skin booster is a procedure that restores moisture and

elasticity by directly injecting active ingredients into the

dermis, which has been damaged by strong summer UV rays,

seawater, sweat, and more.

Representative products include Rejuran Healer, Filorga,

and Belotero.

First, Rejuran Healer contains polynucleotide (PN) extracted

from salmon, and after injection it stimulates fibroblasts in

the skin to help produce collagen and elastin, relieve fine

wrinkles, and promote tissue regeneration. Because of this,

the skin that has become thinner from repeated UV exposure

can be thickened, and improved elasticity can be expected.

Meanwhile, Filorga 135 supplies nutrients such as vitamins,

minerals, and amino acids deep into the skin, providing both

a more even skin tone and lasting moisture.

Dull skin can become brighter again, and the skin texture

can return to a hydrated state that does not cause makeup

to cake.

Belotero Revive delivers low-molecular-weight hyaluronic

acid into the dermis for immediate hydration and improved

elasticity. From right after the procedure, the skin can look

glossy and feel softly settled without tightness, so it is

recommended for those with severe summer dryness.

However, before any skin booster procedure, you must

consult thoroughly with a medical professional.

You need to check your individual skin type and whether

there are any existing issues such as acne or redness, and

confirm whether any ingredients that may cause allergic

reactions are included in order to prevent side effects.

Also, after the procedure, the injection area becomes

sensitive and pigmentation can develop more easily from

sun exposure, so sunscreen should be applied even more

carefully than usual. It is also a good idea to use physical

protection such as a wide-brimmed hat or long-sleeved

clothing.

In addition, since skin recovery may be somewhat slower in

summer, it is advisable to flexibly adjust the interval while

monitoring the skin condition rather than strictly following

the usually recommended procedure spacing. This allows the

skin to go through the regeneration process in a sufficiently

stable state and helps maintain a more natural and elastic

summer complexion.

Minimize 'post-inflammation effects' with cooling and soothing care

If inflammation occurs from strong summer sunlight, sweat,

or seawater irritation, do not leave it untreated; use a

cooling gel or pack immediately to lower the skin

temperature.

If you place a cooling gel containing aloe vera and azulene

on the face for about 10 minutes and then rest for about 5

minutes, repeating this process, the inflammatory response

will quickly calm down and blood flow within the dermis

will stabilize.

In addition, you can promote collagen regeneration in the

skin’s dermis through fractional laser or Rejuran.

Furthermore, using cryo (low-temperature) soothing care

can cool the treated area with a cryo device chilled to -4 to

-8°C, suppressing the release of inflammatory cytokines and

preventing pigment cell activity, thereby reducing the risk of

pigmentation.

An 'inside-out nutrition solution' through diet

External care alone is not enough, so you need to replenish

nutrients that help skin elasticity from within.

Eating plenty of fruits and vegetables rich in vitamins C and

E, such as berries like blueberries and raspberries, and kiwi

and paprika, helps inhibit collagen breakdown. In addition,

omega-3 fatty acids found in salmon, mackerel, walnuts, and

flaxseed help reduce inflammation and strengthen the skin

barrier.

If you also maintain sufficient hydration by drinking at least

1.5 to 2 liters of water a day, skin cells can keep their

moisture and maintain elasticity.

Furthermore, using a DIY nutrient pack made by mixing

makgeolli, sesame oil, honey, spinach, and tofu once or

twice a week can help supply vitamins and minerals to the

skin and regulate skin pH to ease troubles.

'Sustainable elasticity care' through lifestyle habits

No matter how good the products and procedures are, it is

difficult to maintain skin elasticity without healthy lifestyle

habits. Good habits amplify the effects of both external and

internal care.

First, you should get enough sleep every night.

In particular, since growth hormone secretion is concentrated

between 10 p.m. and 2 a.m., at least 7 hours of deep sleep is

needed for smooth skin regeneration.

Also, excessive stress increases cortisol secretion and

promotes collagen breakdown, so to manage stress, it is

important to relax your mind through yoga, meditation, or a

light walk. Rather than intense exercise, light exercise that

promotes blood circulation helps deliver enough oxygen and

nutrients to the skin, making collagen synthesis more active.

Lastly, in summer, wear loose cotton clothing to prevent

troubles caused by sweat and friction, and indoors, set the

air conditioner or fan to an appropriate temperature

(26~28°C) to protect the skin from excessive dryness or

sudden temperature changes.

Creating summer skin that does not get tired with balanced care

To summarize summer skin care information, efforts to block

external irritation in advance and quickly recover from

afterward damage must be balanced.

If you practice all seven steps—sun protection, proper

cleansing, precautions for skin booster procedures, cooling

and soothing care, nutrient intake, and lifestyle management

you can maintain firm, clear skin even against heat and

humidity. This summer, please keep up your care based on

the facts shared today.
