What Is the Relationship with the Skin Barrier? | GD CLINIC

“I keep getting extractions and treatment, so why does it keep coming back?”

During times when sebum production increases, such as in summer,

people often do stronger cleansing, scrubbing, and repeated extraction treatments,

but in some cases the skin becomes even more sensitive and redness lasts longer.

Rather than simply reducing sebum, the importance of care that also looks at the skin barrier 

is also being discussed more often.

Let’s take a look at the relationship between acne and the skin barrier.

What Is the Skin Barrier?

Centered on the stratum corneum, the outermost layer of the skin,

the skin barrier helps prevent moisture loss and protect the skin from external irritants.

Simply put, it can be understood as a thin protective shield for the skin.

When the skin barrier is in a stable state,

moisture is well maintained and the skin can respond relatively stably even to external irritation,

but when the barrier weakens, the skin can dry out easily

and stinging, redness, and heat-like sensations may repeat.

In acne-prone skin, the balance of the skin barrier is often disrupted as sebum and inflammation repeat.

You often hear people say, “My skin is oily on the outside but feels tight and sensitive on the inside.”

Why the Barrier Weakens in Acne-Prone Skin

When acne appears, many people think they need to remove sebum quickly,

so they repeatedly use strong cleansing or exfoliation.

However, excessive stimulation can affect the skin barrier.

For example, the habits below may weaken the skin’s protective layer.

• Strong cleansing repeated several times a day 

• Use of grainy scrubs 

• Repeated use of irritating peeling products 

• The habit of constantly touching the face 

• Repeated extraction 

• Summer UV rays and sweat irritation 

• Friction from wearing a mask for long periods 

Frequent extractions can temporarily remove sebum,

but if repeated, they may leave small amounts of irritation on the skin barrier and lead to redness or pigmentation changes lasting longer. When the skin barrier breaks down, the skin may also respond by trying to produce more sebum to protect itself.

​

This is sometimes explained as one reason why the so-called “dehydrated oily skin” condition, where the surface is oily but the inside feels tight, keeps recurring.

The Problem of Excessive Stimulation

It is easy to come across various home care tips through social media and video content.

However, using multiple products at the same time or repeatedly using highly concentrated ingredients too aggressively may actually cause irritation to accumulate.

Over-cleansing the skin can also affect the skin’s pH balance.

The skin tends to stay relatively stable when it maintains a slightly acidic environment, but repeated strong washing or excessive cleansing may dry the skin and weaken barrier function.

​

Some people with acne-prone skin do not use moisturizer at all, but for barrier recovery, moisturizing care suited to the skin type can also be important.

Moisturizers designed to reduce the burden of clogged pores are also sometimes used.

In addition, ingredients such as ceramides, cholesterol, fatty acids, and panthenol are also discussed as ingredients that may help with skin barrier care.

It is also a good idea to review your current home care products and lifestyle habits together to see whether unnecessary sources of irritation can be reduced.

Recurring Redness and Sensitivity

Even after acne care, red marks or a warm sensation can sometimes last a long time.

In such cases, it may not be just a problem of acne itself, but also a state in which the skin is reacting sensitively to irritation.

When the skin barrier is weakened, even small friction or temperature changes can easily cause redness, and some people feel that their skin recovers more slowly.

In summer, UV rays, sweat, and increased sebum production overlap, which can make skin irritation worse, so rather than repeating only strong treatments, it may be important to consider the current skin condition as well.

Depending on the Skin Condition, Soothing, Regeneration, and Barrier Care May Also Be Considered Together

​

In repeated acne care, not only extraction and sebum control but also

skin soothing and barrier recovery may be considered together.

When sensitivity is severe, care aimed at reducing irritation may be introduced first,

and depending on the condition, soothing care or regenerative care may also be considered.

Depending on the skin condition, LDM treatment or skin boosters may also be combined

to explain an approach toward improving the skin environment.

For example, LDM is sometimes described as a treatment that uses ultrasound energy on the skin

to promote a stable and soothing skin environment,

and skin boosters may also be considered depending on the condition for barrier recovery and improved regenerative conditions.

However, since skin type, inflammation level, and sensitivity vary from person to person,

the method of application and care direction may differ depending on the condition.

​

​

Acne is often difficult to explain as only a sebum problem.

Because sebum, inflammation, the skin barrier, and lifestyle habits can all affect it in combination,

it may be important to look at the current skin condition together.

If you are concerned about recurring acne and sensitivity, rather than repeatedly forcing irritation,

we explain the direction of checking both the skin environment and the skin barrier.

However, some treatments such as extractions, peeling, and laser

may cause temporary redness, irritation, or inflammatory reactions depending on an individual’s skin condition,

so it is important to decide whether to proceed after sufficient consultation.
