Pores & Skin Type: Doctors Diagnose the Causes | [Official] Smart Skin Clinic Group, Tokyo & Yokohama


Pores, Skin Type, Texture, Dullness
That pore is,
Not sebum, but
It might be a hair issue.
Clogged pores aren’t the only reason pores appear prominent. As collagen in the dermis decreases with age, the structures that support the pores become looser, making them appear more open. The reason they don’t improve even after changing your cleansing or skincare routine is that the cause lies within the skin, not on the surface.

How Pores Appear
Pores are,
They are divided into three types.
The treatment you choose will depend on which category applies to you.
This condition occurs when sebum and dead skin cells mix and become trapped in the pores, appearing as white or black spots. They tend to appear on the nose and around the nostrils, and cannot be completely removed by washing your face alone. The best way to address this is to regulate the buildup of dead skin cells itself.
This condition is characterized by pores that appear to be widening into a round shape. It is caused not only by excess sebum but also by a loss of firmness in the dermis, which supports the pores. It is most common on the inner cheeks, and requires rebuilding the skin from its foundation.
This condition occurs when adjacent pores connect, creating a line that appears elongated vertically. It appears as sagging of the cheeks progresses. Since this is caused by overall skin laxity rather than the pores themselves, treatment focuses primarily on restoring skin firmness.
Why Won't They Come Back?
If you only focus on surface-level care,
There are certain groups we can't reach.
Pores, skin texture, and dullness may look different, but they share common underlying causes.
The dermis supports the pores.
The shape of a pore is determined by how densely packed the surrounding dermis is. When collagen density decreases, the pore loses its support, and the opening appears wider. Since cleansers and astringent skincare products only reach the epidermis, they cannot address changes in this layer.
Uneven texture creates shadows
When the fine texture of the skin’s surface becomes uneven, the reflection of light becomes inconsistent. Even the same pores are less noticeable when the skin texture is even, but shadows are emphasized when it is uneven. Rather than focusing solely on the pores, it is important to assess the overall quality of the skin’s surface.
Dullness stems from the same root cause
The reasons why skin appears dull aren’t limited to pigmentation; they also include a loss of translucency caused by a decrease in skin thickness and moisture levels. When the density of the dermis is restored, light is reflected more evenly, changing the skin’s appearance and making it look brighter. This is why we don’t need to consider pores and dullness as separate issues.
Things to Check During a Medical Examination
The shape of the pores (round or elongated), whether they become less noticeable when the skin is gently lifted, and the amount of sebum and the condition of the stratum corneum. We use these three factors to determine the extent to which each type is involved.
That is exactly why our clinic offersInstead of focusing on individual pores, we take a holistic approach based on the overall quality of the skin.We determine the type of condition before selecting a treatment.
Treatment Options
Regarding pores and skin texture,
Three Approaches.
Which ones you need depends on your pore type and skin condition.
Lituo, Serdiem, Jubeluck, and others. These products increase collagen density in the dermis and rebuild the very structure that supports the pores. They are the primary treatment options for enlarged pores and strip-like pores.
JAL Pro Grow Peel, etc. This treatment exfoliates accumulated dead skin cells while also targeting the dermis. It is recommended for those with both clogged pores and dull, lackluster skin.
NeoFound Hydra Injection, Plural, and other treatments. These enhance the skin’s ability to retain moisture and refine its texture. The goal is to create a more even reflection of light, making pores less noticeable.
From the Doctor
Pores are,
Let's look at it from a skin perspective.
"I've tried just about every pore-targeting skincare product out there, but nothing has made a difference"—this is the comment we hear most often from customers seeking advice on pores.
If the problem is caused by surface dirt, cleansing should help. However, if the issue persists, the cause lies not inside the pores but in the surrounding dermis. When the supporting structure has weakened and the pore opening has widened, repeated cleansing won’t reach the problem.
At our clinic, we first examine the shape of your pores and observe how they change when the skin is gently lifted. This is because the appropriate treatment varies depending on whether the pores are round and open or have stretched vertically due to sagging. Based on this assessment, we will present you with several treatment options to consider.
Pores, skin texture, and dullness are often interrelated issues. That’s why we recommend only the treatments you need. We don’t have counselors; a doctor will listen to your concerns from the very beginning.
