The short answer

Pores cannot be completely eliminated, but timely care can prevent them from enlarging. Excess sebum, hormones, stress and the loss of collagen and elastin with ageing all widen pores. Daily habits such as gentle cleansing, hydration, sunscreen and not squeezing help, and DayBeau Clinic Gangnam can add clinical treatments after a skin assessment.

Once enlarged, pores show no signs of shrinking. Regardless of gender or age, pores are a lifelong challenge. In summer, sebum production is more active, and in the dry winter, skin elasticity decreases, causing pores to sag. Enlarged pores are also a major culprit in making the skin texture appear rough. Since bacteria can easily enter through them, they can cause other skin issues as well.

Can we win the battle against pores? Unfortunately, it’s impossible to completely eliminate pores. However, there are ways to prevent them from getting bigger. Since once pores enlarge, they are difficult to shrink, it’s important to manage them in a timely manner. Understanding pores makes it easier to take care of them. Let’s explore why pores enlarge and how to properly care for them.

Why Do Pores Keep Enlarging?

There was a time in life when we could boast of flawless skin without visible pores. The teenage years, when growth hormones activate and sebaceous glands become more active, are typically when pores start to widen. As sebum increases, the pathways for it to exit expand, which means excess sebum naturally causes pores to widen, and when it accumulates, the pores become visibly larger. This is why people with oily skin tend to be more concerned with their pores.

However, there’s no need to blame sebum entirely. Sebum plays essential roles such as hair growth, strengthening the skin barrier, antioxidant functions, and regulating skin immunity. While it’s necessary, it becomes a problem when overproduced.

Aging as a Major Cause of Pore Expansion

Aging also contributes significantly to pore enlargement. As skin ages, collagen and elastin decrease, causing the skin around the pores to lose its elasticity. When this happens, the skin’s ability to support the pores diminishes, leading to their expansion. These enlarged pores are often referred to as “vertical pores.” Therefore, caring for skin elasticity is also crucial for minimizing pore enlargement.

What’s Important in Pore Care?

Did you know that homecare is vital for managing pores? Small, proper habits can help prevent pore enlargement. Let’s explore some helpful skincare practices.

1.Don’t Squeeze Pores

When sebum blocks the pores and comes into contact with air, it oxidizes and turns into blackheads. Squeezing or rubbing can damage the surrounding skin and make pores appear larger. Particularly around the nose, where blackheads are most common, avoid pressing too hard since it can lead to redness due to the abundance of blood vessels. Instead of squeezing, use an oil-based product to gently dissolve the sebum.

2.Stress is the Enemy of Pores

Hormonal changes due to stress increase sebum production. As we discussed earlier, excessive sebum can clog pores and trigger skin problems. Managing stress and maintaining a regular lifestyle, including getting enough sleep, is crucial for pore health.

3.Avoid Harsh Facial Stimulation

Excessive pore strips, exfoliating packs, or extreme temperature changes (like washing your face with hot water and then rinsing with cold water) can harm the skin and exacerbate pore problems. Forcefully removing sebum or rubbing repeatedly can stimulate sebum production and increase skin sensitivity. Giving your pores a break is essential to prevent further enlargement. Using mild, slightly acidic cleansing products is recommended.

4.Monitor Skin Temperature

Skin temperature plays a significant role in sebum production. When skin temperature rises by just 1°C, sebum secretion increases by about 10%. Similarly, a 30-60% increase in humidity can boost sebum production by about 20-30%, contributing to pore enlargement. Keep this in mind when managing your skin.

5.Hydration is Essential

Dry skin naturally loses elasticity, which can lead to increased sebum production as a compensatory mechanism to retain moisture. If you have oily skin that’s also dehydrated, maintaining proper hydration is key. Drink plenty of water and use moisturizing creams that don’t contain oils to keep the skin hydrated and smooth.

6.Don’t Skip Sunscreen

While applying sunscreen doesn’t shrink pores, it plays an important role in preserving skin elasticity and preventing collagen and elastin breakdown, which are crucial for maintaining pore size. Since UV rays can cause oxidation and inflammation in sebum, leading to enlarged pores, it’s important to apply sunscreen every day and reapply throughout the day.

7.Nourish with Proper Diet

A diet rich in antioxidant-packed fruits and vegetables like tomatoes, avocados, strawberries, broccoli, and blueberries can be beneficial for skin health. Avoid high-sugar and high-fat foods. Nuts, which contain unsaturated fatty acids, help maintain the normal function of the skin's stratum corneum, keeping the skin smooth and aiding in pore reduction. Zinc also helps suppress DHT hormones, which control sebum production. A daily intake of 15-30 mg of zinc is recommended.

Pore-Caring Cosmetics: Check These Ingredients

While cosmetics claiming to reduce pore size may not offer dramatic effects, using products that clean sebum and enhance skin elasticity is the starting point for effective pore care. Check out the key ingredients and their benefits for pore management:

  • Niacinamide : Inhibits sebum production, excellent for brightening, anti-inflammatory effects, and reducing pigmentation caused by acne.
  • Retinol, Retinal : Helps reduce acne, controls sebum production to improve pores, promotes exfoliation, and offers anti-aging benefits.
  • Adenosine : Improves wrinkles.
  • Vitamin E : Antioxidant effects (using products with Vitamin C, which promotes oxidation, enhances the antioxidant power for even better results), and moisturizes.
  • AHA, BHA : Exfoliate, reduce sebum (BHA should be used in small amounts regularly).

Pore Treatments: Find the Right One for You

Lifestyle habits and using the right cosmetics may not be enough to significantly reduce pore size. For noticeable results, dermatological treatments are essential. By receiving treatments tailored to your needs, you can achieve double benefits—not only reducing pore size but also addressing other skin concerns.

  • Skin Botox : Unlike regular Botox injections into the muscles, this treatment involves injecting small amounts of Botox into the surface skin and dermis layers. It helps reduce sebaceous gland activity and the excessive keratinization process, smoothing the skin. It also affects the hair follicles, causing slight swelling and a tightened feeling. The key advantage of this treatment is the immediate effect. However, the effect typically lasts for only 2-3 months, so re-treatment is often required. The frequency can vary depending on the individual.
  • Needle RF, Radiofrequency : Needle-based RF or non-invasive RF methods (where the current is transmitted through the surface of the skin) can help shrink pores by delivering RF energy deep into the skin. It’s recommended for people who are concerned with both pores and skin elasticity.
  • Ultherapy : Ultherapy is performed using three different tips, depending on the depth of ultrasound penetration. The shallowest, 1.5mm tip, targets the skin surface and dermis layer, stimulating collagen and elastin production. Ultherapy is often combined with treatments like skin Botox or other lasers for pore care rather than used alone.
  • Non-ablative Fractional Laser
    Traditional methods that create deep scars can help with pores but require a long recovery time, which can interfere with daily life. To overcome this drawback, lasers like TULUM and Erbglass, which focus only on the surface, are gaining attention for their ability to improve pores.
  • Skin Booster
    A skin booster does not directly improve pores. Instead, it helps speed up recovery when combined with other treatments. If you're looking to improve both pores and overall skin condition, combining treatments like lasers, skin boosters, and skin Botox could be a great option.
  • Mirajet
    This treatment creates tiny wounds in areas with severe pore issues and injects medication into the skin. The medication helps with the healing of the wounds and ultimately leads to the reduction of pores. While Mirajet can be effective on its own, it is often combined with treatments like radiofrequency for enhanced results.
  • Double Tight
    Double Tight uses microneedles to introduce both radiofrequency energy and medication into the skin. The treatment stimulates growth factors, and as the tiny wounds heal naturally, it aids in skin regeneration. This treatment can reduce pore size, improve skin elasticity, lifting, and overall texture.
  • Did you know that there are so many different treatments available for pore care? You can customize your treatment plan with a variety of combinations based on your personal preferences. To create an effective treatment plan, it's essential to understand your skin condition accurately. Be sure to consult with a trusted clinic and have a one-on-one consultation with a doctor to receive a proper diagnosis. Don’t delay in addressing your pore concerns.

FAQ

Questions, answered honestly

Is it possible to have poreless skin?

Pores cannot be completely eliminated, but you can prevent them from getting bigger and reduce their visibility. Managing them early matters because enlarged pores are hard to shrink.

Why do pores get bigger?

Excess sebum widens the pore opening, and ageing reduces collagen and elastin so skin supports pores less well. Stress, dehydration and UV exposure can also contribute.

Should I squeeze or use pore strips?

No. Squeezing, harsh strips and exfoliating packs can damage surrounding skin and stimulate more oil. Gentle, slightly acidic cleansers and oil-based products to dissolve sebum are usually kinder.

Does sunscreen help with pores?

It does not shrink pores, but it helps protect collagen and elastin and limits UV-related sebum oxidation, which supports pore size. Daily use and reapplication are advised.

What clinic treatments help with pores?

Options may include lasers, RF microneedling, chemical peels and cleansing facials. A DayBeau Clinic Gangnam dermatologist picks treatments based on your oil levels, texture and elasticity.
