For enlarged pores, choose treatments tailored to the underlying cause.
As an Assistant Professor, Associate Ward Director, and Chief of Dermatopathology at the university hospital dermatology department, I deepened my expertise through academic presentations and paper publications both domestically and internationally. I have handled a wide range of treatments, from birthmark therapy in children to adult pigmentation concerns, utilizing various lasers and injection therapies, while also contributing to community healthcare. Through encountering numerous cases, I strongly felt the potential and necessity of aesthetic medicine, resolving to pursue further expertise. Building upon my solid dermatological knowledge and meticulous diagnostic skills, I value treatments that gently support each individual's skin while bringing out its inherent beauty.
Enlarged pores—I bet many of you are concerned about them!
The cause is partly genetic predisposition, but it also changes with age and hormonal balance.
People in their teens to thirties tend to have higher sebum production, and factors like hormonal balance and climate can further increase sebum secretion. This makes pores on areas like the nose, which lack excess skin, particularly prone to enlargement.
Excess sebum can physically stretch and enlarge pores. When dead skin cells clog pores, they oxidize on the surface, darkening and becoming more noticeable.
And if you leave those pores untreated, they may become permanently enlarged.
Additionally, for those in their 30s and beyond, age-related changes such as enlarged pores due to sagging also become apparent, so we believe tailored treatments and skincare management are necessary for each individual.
I am Dr. Aya Hayama, a board-certified dermatologist.
So far, we've introduced formulations that can be treated with BIANCA. Now, we'd like to propose treatments tailored to your symptoms.
First, regarding enlarged pores.
Improving sebum retention, exfoliation care
If sebum production is excessive and pores become clogged with dead skin cells, regular removal is necessary.
Of course, peeling is highly recommended here.
For cosmetics, we recommend medical-grade products containing lactic acid, glycolic acid, salicylic acid, or LHA to enhance skin metabolism.
As for treatments, I consider HydraFacial to be a good option because it combines light peeling with suction and pressure cleansing.

Dermal collagen production
If enlarged pores remain open, it is necessary to tighten the pores affected by sagging.
Many methods that stimulate fibroblasts in the dermis to produce collagen are effective.
TCA (trichloroacetic acid) contained in massage peels and bio peels is the least invasive treatment.
Other recommended treatments utilize direct wound healing (natural healing) capabilities, such as Dermapen, Potenza, Juvellook, and injections of Rejuran and Senecos.

Sebum secretion suppression
Controlling sebum production is inherently difficult, but oral vitamin B2 and B6 supplements, as well as oral isotretinoin, are effective treatments. However, isotretinoin can cause dryness, liver damage, and lipid abnormalities, and requires a period of contraception, so caution is necessary during treatment.
I also think it's useful to effectively incorporate retinol into cosmetics.
Vitamin C
Personally, when undergoing the above treatment, I recommend supplementing with vitamin C—essential for collagen production—through cosmetics, Mesona J infusion, intravenous administration, or oral intake targeting 3000 mg per day.
