7 Ways to Protect Your Skin from Sweat and UV Rays in Summer

Summer,

The moment when skin becomes the most sensitive!

Hello. This is Jamsil Gounsesang Dermatology Clinic!

Even if you stand under the sun for just a moment, sweat starts dripping down your forehead and the sides of your nose,

and your face looks shiny in the mirror,

your pores seem to keep getting larger, and breakouts keep appearing..

In summer, many people can feel that their skin has become especially sensitive

and unstable.

Actually, summer skin is not just difficult because it is

“hot.”

As temperatures rise, sweating increases and sebum production becomes more active,

and with stronger UV rays on top of that, the skin is hit all at once by a complex

set of external irritants. Skin that must constantly respond to changes in the external environment becomes more and more tired,

and if it is not properly cared for at this time, problems such as enlarged pores,

trouble, and loss of elasticity can increase noticeably.

In fact, many people reach the end of summer and say,

"Why does my skin feel so dull?" "It seems like my pores have

become larger."

Seasonal changes are clearly reflected in the skin, and summer in particular can be described as the environment that most quickly breaks down the skin.

So how should you care for your skin to keep it a little healthier during the summer?

The 7 methods introduced now are not special secrets,

but basic habits that anyone can practice.

However, when these basics are followed, the skin can

show remarkable resilience even in summer. Try practicing just one thing a day.

Your skin remembers how faithfully you cared for it,

and it will respond in return.

1. Wipe away sweat immediately

• Fresh and irritation-free

After coming home from going out in the summer, have you ever looked at your shiny

forehead and the sides of your nose in the mirror and worried, "I feel like I'm going to break out again..."?

Sweat is a natural physiological response that regulates body temperature, but if it stays on the skin for too long, the story changes. It mixes with sebum, dust, sunscreen residue, or makeup residue, can clog pores,

and may become a cause of skin trouble.

But that does not mean you should just rub it off carelessly with any towel.

Towels carry a risk of bacterial growth, and they can be quite irritating.

In that case, it is much safer to gently wipe it away with a cleansing pad with good absorbency or a cotton pad soaked in a soothing toner. In particular, wet wipes with a strong alcohol content can cause skin irritation, so it is important to check the ingredients carefully before use.

What touches the skin may seem very small, but one small habit

can change the direction of your skin.

Gentle cleansing and exfoliation

• Protecting the skin barrier

The hotter the weather gets, the more you may want to increase how often you cleanse.

But cleansing is much more about doing it “properly” than doing it “a lot.” Twice a day, morning and evening.

That is enough. After gently cleansing with lukewarm water and a mildly acidic cleanser,

you can finish with cool water to slightly tighten the pores.

In summer, skin often feels dirtier because of sweat and oil, but if you overdo exfoliation,

the skin barrier may become weaker and more sensitive.

Exfoliation care should be done about once or twice a week, choosing a low-irritation product such as an enzyme cleanser or a gel-type product,

and managing it according to your skin condition. The important thing is not “peeling it off,” but “refining” it.

Skin does not recover quickly when treated harshly.

Only gentle and repeated care becomes the force

that changes the skin.

Soothing + moisture care

• Preventing inner tightness

Summer skin often falls into a state of “inner dryness,” where the outside is shiny but the inside feels tight.

Even if it looks oily on the surface, the skin's internal moisture is often lacking. If this condition continues, sebum production becomes even more active, pores may look larger, and breakouts can follow.

That is why soothing and moisture care are essential.

Use a moisturizing essence or mist containing ingredients that may help soothe the skin, such as aloe, centella asiatica, and panthenol, to steadily replenish moisture from within.

Moisture supply is basic regardless of skin type.

Especially for oily skin, the less moisture it has, the more sebum it may produce, so using gel-type products with a fresh finish can be even better.

Now is the time to pay closer attention to the skin's signals, which are easy to overlook if you only look at the surface.

The skin speaks about its condition before we do.

Sun protection

• The basics of summer skin care

When summer comes, you have probably heard at least once that “sunscreen is a basic.”

Even so, many people still ask, "Do I really need to apply it if I'm only indoors?"

But UV rays pass through glass.

Did you know that skin is exposed to UV rays even by a window at the office, in the driver's seat of a car, or under the shade on a cloudy day?

UV rays destroy collagen, reduce elasticity, and are the main cause of not only melasma, freckles, and blemishes, but also enlarged pores.

It is no exaggeration to say that 80% of summer skin problems are directly or indirectly linked to UV rays.

That is why the key is to use a product with SPF 30 or higher and PA++ or higher, and to reapply it consistently every 2 to 3 hours rather than only once a day.

In particular, if you are often outdoors or plan to go swimming, a waterproof product can help, but it is not completely waterproof, so you must reapply after sweating or getting wet for the protection to continue.

Sun protection is not just about preventing changes in skin color.

Please remember that it is the most basic and also the most effective habit for slowing the pace of skin aging.

Customized care by skin type

• A routine that suits my skin

The question, “If everyone does the same thing, will everyone get the same results?” does not have an exception when it comes to skin either.

Even with the same season and the same products, reactions can differ completely depending on skin type. That is why the key to summer care is finding a routine that fits you.

1. Oily skin

In a season when sweat and sebum both increase, you may easily suffer the double burden of shine and enlarged pores.

Careful sebum management with a low-irritation cleanser twice a day, and fresh moisture care that reduces oil while replenishing hydration, are the basics.

2. Combination skin

An in-between skin type where the T-zone is oily and the U-zone is dry.

Different care is needed for different areas.

Managing the T-zone with a sebum-control toner and the U-zone with a moisturizing serum, and balancing things out with a multi-mask pack, can also be effective.

3. Dry skin

Inner dryness can worsen even in summer.

Even if products look lightweight, hydration layering should be the foundation, and at night it is necessary to seal in moisture with a rich cream.

4. Sensitive skin

Since UV rays, heat, and sweat can all be irritating, care should start from cleansing.

A mildly acidic, low-irritation cleanser and cooling care using soothing ingredients such as centella asiatica and madecassoside are the basics.

As such, adjusting products and routines differently according to skin type is not simply a matter of “cosmetic preference.”

It is the safest way to reduce irritation and help the skin restore its balance on its own.

Lifestyle habits and diet

• Skin is a mirror of the body

The skin in the mirror is not made by cosmetics alone.

What you ate, how much you slept, and how much stress you have recently been under are all clearly reflected in the skin.

That is why skin care should begin with a lifestyle check.

First, sleep. From 10 p.m. to 2 a.m. is the time when skin regeneration is most active. During this time, deep sleep is needed for damaged skin to recover.

It is best to avoid insomnia and late-night snacking habits, and to go to bed at a consistent time whenever possible.

Next is diet. Spicy foods, snacks high in sugar, and greasy foods can increase sebum production and worsen inflammatory breakouts.

On the other hand, a diet rich in vegetables and fruits with abundant antioxidants, as well as vitamins B, C, and E, helps improve the skin's immunity and recovery.

Water is also important. Drinking at least 1.5 to 2 liters of water a day helps prevent inner dryness and balance sebum.

The saying “what you eat becomes your skin habit” is truly not wrong.

Cooling and elasticity care

• Lowering skin temperature is the real summer care

In summer, the skin's temperature actually rises.

And this rise in temperature can cause more problems than you might think. Pores expand, sebum production increases, and skin elasticity starts to decrease.

That is why “cooling care” is getting attention these days.

Without making it complicated, after cleansing, lightly wipe the skin with toner that has been stored in the refrigerator, or gently press the skin with ice wrapped in a towel.

However, do not apply ice directly to the skin for a long time; the key is to cool it briefly and lightly.

Cooling masks, soothing pads, and moisturizing mists can also help lower skin temperature while at the same time providing soothing care and hydration.

These products can reduce heat and redness without irritating the skin, so they are especially effective after outdoor activities.

Also, even in summer, efforts to support collagen production and maintain elasticity should continue.

Functional ingredients such as retinol, peptides, and vitamin C stimulate the deeper layers of the skin and help make it firmer.

However, these products should be used at night, and in the daytime, strict sun protection is essential.

The more sensitive the season becomes for the skin, the more we need to focus on the basics and the essentials.

The safest and most effective approach to summer skin is to “reduce, soothe, and protect.”

Skin remembers 'habits more than seasons.'

Summer skin problems may seem to appear suddenly, but in fact they are the result of small daily choices accumulated over time.

More important than one or two intensive care sessions is consistently following a routine that suits your skin—this is exactly what “continuity” means.

Skin senses the season more sensitively than we do and reacts quickly according to lifestyle habits.

To keep skin from breaking down amid sudden weather changes, strong UV rays, frequent sweating, and increased sebum production, your usual care habits need to become a protective barrier.

The routine you practice now may not feel like a big change at the moment.

But as the season passes, I hope you remember that you can be rewarded with skin that is calmer and more stable than ever.

Thank you.
