Mapo-gu Dermatology: How to Improve Your Skin by Checking Your Diet First

Hello.

I’m Dr. Kim Gaeul.

No matter how much you pay attention to skincare, if breakouts keep appearing, have you ever felt frustrated?

You may have wondered whether the products don’t suit you, or why the problem keeps recurring even after trying treatment at a clinic.

At times like that, it may help to think from a slightly different angle.

That is, your diet. In fact, many people already know this.

You already know which foods are bad for your skin.

But even so, it is not easy to put that into practice, and that is the hardest part.

Patients who visit the Mapo-gu dermatology clinic also share these kinds of concerns often.

During consultations, common eating patterns begin to stand out.

Now may be the time to take another look at your eating habits.

1. Refined carbohydrates

The more white foods you eat, the more sensitive your skin can become.

Refined carbohydrates are forms in which most of the fiber has been removed through milling and processing.

As a result, they are absorbed quickly in the body and cause blood sugar to rise sharply.

When blood sugar rises, insulin secretion increases,

and in this process, the sebaceous glands are overstimulated.

As a result, acne can develop more easily, and inflammation may become worse or last longer.

At the Mapo-gu dermatology clinic, we often see skin changes after patients reduce their intake of refined carbohydrates.

✔ Foods to be careful with White rice, white bread, ramen Jam, syrup, various baked goods

✔ Alternative meals Brown rice, black rice Whole wheat bread, mixed-grain foods 2. Oily foods

A single oily meal can be the beginning of clogged pores.

Foods high in fat can raise blood triglyceride levels,

which may eventually lead to increased sebum secretion and inflammatory responses.

Especially if your breakouts keep recurring, or if your skin is red and sensitive,

then adjusting your diet acts as a more important variable than you might think.

In consultations at the Mapo-gu dermatology clinic, when oily eating habits continue,

we often see a pattern where breakouts worsen.

✔ Foods to avoid Fried foods such as chicken and pork cutlet Pork belly, butter, mayonnaise Fast food

✔ Recommended methods Low-fat proteins such as chicken breast and tenderloin Focus on grilling, steaming, and boiling Use plant-based fats such as olive oil and perilla oil

At the Mapo-gu dermatology clinic, there are also quite a few patients in the early stages whose skin stabilizes with diet changes alone. 3. Dairy products

The gut stays quiet, but the skin responds instead.

Depending on the individual, dairy products can act as a trigger for breakouts.

Especially for people who are lactose intolerant or have sensitive skin,

it is not uncommon to see skin changes after consuming dairy products.

In addition, dairy products with a high fat content may stimulate sebum secretion even more.

At the Mapo-gu dermatology clinic, we consistently see cases where skin condition improves after reducing dairy intake.

✔ Dairy products to be careful with Milk, ice cream Cheese, sweetened yogurt

✔ Alternative foods Soy milk, almond milk Lactose-free milk Unsweetened plain yogurt Why do foods affect the skin? The skin does not change through external care alone.

It also responds very sensitively to changes happening inside the body.

Looking at the representative connection patterns,

blood sugar increase → insulin increase → excess sebum changes in the gut environment → increased inflammatory response excess fat → clogged pores → breakouts

In this way, the skin is often the “result,” and diet is often the “cause.”

At the Mapo-gu dermatology clinic, we analyze skin condition while also considering these internal factors.

In the end, you should remember that one of the most basic ways to stabilize the skin is diet. Checklist when breakouts flare up ❌ Meals to avoid

White rice, wheat flour, snacks Fried foods, sweetened drinks Milk, cheese

✅ Recommended meals

Brown rice, mixed grains, whole wheat Sweet potatoes, bananas, nuts Grilled or steamed protein Soy milk, plain yogurt Unsweetened tea, plain water

At the Mapo-gu dermatology clinic, we check diet and lifestyle together like this and guide patients toward ways to improve their skin. Questions we often hear in the consultation room

Q. Do I have to stop dairy completely?

No. If you do not have any problems, moderate intake is fine.

However, for people whose breakouts keep recurring or whose gut function is sensitive,

temporarily reducing it may be helpful. Q. What food should I cut back on first?

Refined carbohydrates. Simply reducing wheat flour and sugar intake can often change the skin’s reaction. Q. How much should oily foods be controlled?

We recommend reducing them to 2–3 times a week or less and changing the cooking method from frying to mainly grilling or steaming. The skin responds according to what you eat.

Sugar, oil, and dairy products can increase sebum and inflammation.

When breakouts appear, before skincare, first think back to what you ate yesterday.

Foods that help improve skin are important, but even more than that, reducing the factors that burden the skin may be the faster start to improvement.

At the Mapo-gu dermatology clinic, we provide guidance on improving skin while considering not only procedures but also daily habits.

Small changes in eating habits can make a surprisingly big difference.

Why not start by choosing one meal differently today?
