Hello. This is Jamsil Gounsesang Dermatology!

Acne and eating habits: a deeper connection than you might think Acne is often seen as only a temporary skin problem caused by puberty or hormonal changes.

However, research has confirmed that everyday lifestyle, especially eating habits,

is closely linked to skin condition.

Recent domestic research results have also been reported in an international academic journal,

showing that instant foods and fatty meals tend to worsen acne.

This result shows that it is not simply a phenomenon seen in people with oily skin.

It shows that the foods we usually choose and how we eat them can have a direct

impact on the skin environment.

Many people may have experienced, based on personal observation, that after eating certain foods,

their skin becomes more sensitive or breakouts get worse. In fact, these personal experiences

are also being scientifically supported.

So, which foods worsen acne, and which foods help the skin recover?

Today, let’s take a step-by-step look at the relationship between acne and food,

from the causes to prevention methods and helpful foods.

  1. Foods that worsen acne Many people pay attention to skin care but tend to think that eating habits are not very important.

However, one common trait seen among acne patients is a high intake of instant foods and fatty foods.

These small habits, though not visible, eventually show up in the condition of the skin.

First of all, fast food and processed foods are considered major contributing factors.

Hamburgers, ramen, doughnuts, croissants, waffles, and carbonated drinks are high-glycemic-index foods

that raise blood sugar quickly. When blood sugar rises suddenly, insulin is secreted excessively,

which can stimulate sebum production and make acne worse.

Fatty meats and fried foods also require caution.

Samgyeopsal, chicken, samgyetang, boiled pork, and some nuts such as peanuts can increase sebum production.

Research has also reported that when these foods are consumed, acne can increase or worsen by 13% to

more than 100%.

In addition, dairy products can also have an effect.

Cheese and processed milk products are pointed out as potentially changing hormonal balance

and being linked to acne development. It is necessary to manage this consistently,

because the effect goes beyond simply increasing sebum and can also affect internal balance.

Lastly, irregular eating habits cannot be overlooked.

What matters as much as what you eat is when and how you eat.

Skipping meals frequently or repeatedly overeating can disrupt the body’s rhythm and contribute to acne.

In the end, oily and sugary foods, along with irregular meal patterns, can be said to be major factors

that worsen acne. Therefore, for skin health, it is essential not only to manage the outside of the skin,

but also to reconsider the foods and habits we encounter every day.

  1. Foods that help acne When managing acne, many people first think of cleansing or skin care methods.

But the skin ultimately reflects the body’s internal balance.

In other words, what you eat directly affects the condition of your skin.

In particular, foods rich in certain nutrients can help reduce acne and calm the skin.

So which foods play a positive role in skin recovery? Let’s look at five representative ones.

First,

lettuce and spinach are rich in water and fiber, which help relieve constipation, and their vitamin A, E,

and beta-carotene content helps suppress sebum production.

These ingredients promote the regeneration of epithelial cells, helping the skin recover more quickly and

positively affecting the prevention of recurring acne.

Second,

cabbage contains large amounts of vitamins A, C, E, B6, and sulfur compounds.

These components play an important role in reducing inflammation in the skin and helping hormonal balance.

In particular, sulfur has excellent anti-inflammatory effects and is useful for calming redness and irritation

caused by acne.

Third,

tomatoes are rich in lycopene, a powerful antioxidant.

Lycopene not only protects the skin from ultraviolet rays but also has excellent ability to regulate sebum production.

It also provides moisture to the skin and helps reduce inflammation, so it can help improve not only acne

but also blackheads.

Fourth,

legumes are rich in zinc, which helps reduce sebum production and normalize the skin’s keratinization process.

In addition, the isoflavones in soybeans help relieve acne caused by hormonal imbalance,

and contribute to the regeneration of damaged skin and wound healing.

Fifth,

green tea contains catechins and flavonoids, giving it strong anti-inflammatory and antibacterial effects.

These ingredients inhibit the growth of acne-causing bacteria and calm the skin, helping maintain clear and healthy skin.

With consistent intake, you may expect your skin to become clearer from within.

In the end, foods for skin health do more than simply supply nutrition;

they play an important role in regulating and restoring the skin’s internal environment.

If acne is a concern, it is necessary to make changes starting with eating habits, just as much as with external care.

  1. Lifestyle habits that protect the skin [Jamsil Gounsesang Dermatology] Acne Is Influenced by Food. image 10

One part of acne management that is easy to overlook is lifestyle habits.

No matter how good the food you eat is or how properly you cleanse your face,

if your lifestyle pattern is irregular, the skin quickly loses balance and problems tend to return.

In the end, the skin can be said to be like a mirror that reflects the body’s condition and daily rhythm.

First, regular meals are essential.

Eating balanced meals at set times stabilizes the body’s hormonal rhythm and regulates sebum production.

On the other hand, skipping meals or eating irregularly late at night makes the skin react sensitively

and increases the likelihood of acne.

Adequate hydration is also important.

Drinking about 1.5 to 2 liters of water a day helps balance skin moisture and prevents excessive sebum

production caused by dryness. Rather than drinking only when you feel thirsty, it is helpful to develop the habit

of sipping small amounts throughout the day.

Lastly, sleep and stress management are key to preventing acne.

Staying awake late at night disrupts the body’s hormonal balance, which can worsen acne.

In particular, getting sound sleep during the nighttime hours when growth hormone is actively secreted is beneficial for skin recovery.

In addition, stress increases cortisol levels and intensifies inflammatory responses in the skin, so it is necessary

to make an effort to relieve tension in ways that suit you, such as meditation or light exercise.

In the end, the skin faithfully records lifestyle habits.

Since the small habits repeated every day come together to determine the skin’s health,

it is important not to forget that regular meals, adequate hydration, quality sleep, and stress management

are the foundation of acne care. In the end, the choices I make today determine my skin condition tomorrow.

The skin remembers eating habits.

Acne is not just a temporary skin concern that appears only during puberty.

Depending on what foods we choose and what lifestyle habits we continue, the skin changes.

If you frequently consume oily and sugary foods, that result appears clearly on the skin,

and conversely, if you consistently consume foods beneficial to the skin such as vegetables, legumes,

and green tea, the skin gradually shows healthy changes.

The key to acne care is not a complicated or special method.

Rather, the power of small habits that can be practiced every day changes the skin.

Basic lifestyle habits such as regular meals, sufficient hydration, good sleep, and stress management

play an important role in restoring skin balance and easing acne. In the end, what I choose today determines

the condition of my skin tomorrow.

The skin does not change overnight.

But good habits are definitely recorded in the skin.

Please remember that the small efforts you start making now will accumulate over time and lead to healthier,

clearer skin.

Acne may be part of our lives,

but with consistent care and the right choices, it can change significantly.

We hope you will start making small changes for your skin today.

Thank you.
