Enlarged Pores: How to Fix Them?

Enlarged pores are caused by a combination of factors such as oil buildup, aging keratin and collagen loss — understanding the causes and types is the first step to choosing an effective treatment.

Key Takeaways

The bottom line
  • Enlarged pores can be divided into five types — keratin, oily, aging, dehydration and inflammatory — each requiring a different intervention strategy.
  • Incomplete makeup removal, staying up late, improperly squeezing comedones, and neglecting sun protection are the most common daily habits that worsen enlarged pores.
  • Skin booster injections, Hydrafacial and IPL photorejuvenation are three mainstream medical aesthetic approaches for improving enlarged pores, each with a different mechanism of action.
  • Over-exfoliation or over-cleansing damages the skin barrier and may actually trigger inflammation and worsen pore dilation.
  • Before any medical aesthetic intervention, a licensed physician should assess skin type and classification — a personalized plan is more targeted than a single standardized course of treatment.

What Causes Enlarged Pores? Which Medical Aesthetic Treatments Can Help?

Enlarged pores refer to the visibly rough appearance that occurs when pore openings on the skin's surface widen due to excess sebum secretion, keratin buildup, collagen loss, or chronic skin inflammation. Based on their causes, they are typically divided into five clinical types: keratin type (slow metabolism of aged keratin cells), oily type (overactive sebaceous glands), aging type (reduced collagen and elastic fibers), dehydration type (weakened moisture-locking mechanism), and inflammatory type (triggered by acne or allergies). Common contributing factors include incomplete makeup removal that leaves cosmetic residue blocking pores long-term, staying up late that disrupts sebum metabolism, improper squeezing of comedones that damages follicle walls, UV exposure that accelerates collagen breakdown, and over-exfoliation that damages the skin barrier. Among evidence-supported non-surgical medical aesthetic options are skin booster injections (Mesotherapy), which deliver hyaluronic acid and nutrients into the dermis via microneedle for instant hydration and improved elasticity; Hydrafacial with HIFU thermal effect to stimulate dermal collagen regeneration and shrink pores structurally; and Lumeca IPL photorejuvenation, which uses intense pulsed light to promote collagen and elastic-fiber renewal. At ID Cosmetic Clinic in Markham/Toronto, Dr. Dan Xu (MD, CCFP) provides personalized assessments of skin type and pore classification and bilingual medical-grade consultations before recommending options such as skin booster injections, Hydrafacial, or IPL.

Your skin has more than twenty thousand pores, and when the temperature rises these pores prompt the sebaceous glands to produce large amounts of oil — the hotter it is, the more vigorous the oil secretion becomes. In daily life, if we do not regularly cleanse and exfoliate the skin, dead skin and keratin will accumulate at the pore openings and cause blockages. This obstruction allows keratin, sebum and other impurities to build up continuously within the pores.

When these substances are not removed in time and come into contact with air, they oxidize easily, and this oxidized environment more readily provides a breeding ground for bacteria. Over time, these bacteria cause the pores to keep expanding, resulting in visibly enlarged pores. In addition, this situation is often accompanied by redness and breakouts.

Types of Enlarged Pores:

Enlarged pores can be divided into the following types:

  1. Keratin type: This mainly occurs because the skin cannot effectively remove and metabolize aged keratin cells, causing the stratum corneum to gradually thicken and making pores appear more obvious. In addition, when the sebaceous glands produce too much oil, the pore blockage worsens, further accentuating the pores.

  2. Oily type: Some people’s skin may naturally produce more oil due to genetic factors, which easily triggers oily-type enlarged pores. Furthermore, over-cleansing the skin or using overly harsh cleansers and cosmetics may stimulate the sebaceous glands to produce more oil, making the pores more noticeable.

  3. Aging type: As we age, the collagen in the skin gradually diminishes, causing the skin to lose its original firmness and making pores appear larger. At the same time, the elastic fibers in the skin become damaged, further reducing skin elasticity and making pores more prominent.

  4. Dehydration type: The skin’s moisture is easily lost due to various external factors such as dry climate, wind, sun exposure, or spending long periods indoors with air conditioning. As we age, the skin’s own moisture-locking mechanism also gradually weakens, making the skin more prone to dehydration.

  5. Inflammatory type: Acne and comedones are two common skin inflammation problems; both can cause pore blockage and inflammation, leading to pore dilation. In addition, allergic reactions to certain substances can also trigger skin inflammation, worsening the enlarged-pore problem.

Causes of Enlarged Pores

Enlarged pores are a skin concern that many people care about, and several factors can contribute to them. Below are a few common causes of enlarged pores:

  1. Incomplete makeup removal: For people who wear makeup frequently, using only an ordinary cleanser may not fully remove makeup and sunscreen residue from the face. Incomplete makeup removal easily allows cosmetics and oil to block the pores for extended periods. This prolonged blockage can also trigger breakouts, further enlarging the pores. Therefore, using a makeup remover followed by a gentle cleanser is a necessary step.

  2. Irregular lifestyle: Some bad habits in daily life — such as lack of adequate sleep, smoking, or excessive intake of sweets — can all negatively affect the skin. Staying up late in particular disrupts the skin’s normal metabolism, increasing sebum secretion and pore blockage. In addition, excessive sugar intake damages collagen, causing the skin to lose its original elasticity and leading to larger pores.

  3. Incorrectly squeezing comedones: When faced with comedones on the face, many people’s first reaction is to try to squeeze them out. But if the squeezing method is improper, it may not only cause pore inflammation but also damage the skin and even leave hard-to-remove scars, making the pores more noticeable.

  4. Neglecting sun protection: UV rays are the skin’s natural enemy; they not only cause sunburn but, more seriously, prolonged UV exposure damages the collagen in the skin, accelerating skin aging and making pores more prominent.

  5. Insufficient moisturizing: Whether your skin is oily or dry, it needs adequate moisture to maintain the skin’s water-oil balance. Choosing the right moisturizing products based on your skin’s actual condition is crucial.

  6. Over-exfoliation: Frequently or excessively using exfoliating products, or over-cleansing the skin, can damage the skin’s stratum corneum. This not only makes the skin sensitive but may also trigger inflammation, worsening the enlarged-pore problem.

Frequently Asked Questions

Frequently Asked Questions

Can enlarged pores be completely eliminated through daily skincare?
Daily skincare can reduce the visual prominence of pores to some extent — for example, oil control, hydration and gentle exfoliation help reduce blockage. However, pore size is influenced by genetics, age and skin structure, so skincare products alone usually cannot fundamentally change pore size. Medical aesthetic treatments can provide deeper intervention at the structural level of the dermis.
Do both oily and dry skin develop enlarged pores?
Yes, both skin types can develop enlarged pores, but the causes differ. Oily skin often develops enlarged pores due to excess sebum causing blockage and dilation, which is the oily type; dry skin may show more obvious pores because dehydration reduces elasticity and loosens the pore edges, which is the dehydration type. Accurately identifying the type helps you choose targeted care or treatment.
How many skin booster injection sessions are needed to see results for enlarged pores?
Results from skin booster injections vary depending on individual skin condition; some people notice improved hydration and a visual reduction in pores after the first treatment. Typically a course of 3 to 5 sessions is recommended to achieve more stable improvement, and the exact number should be determined by a physician based on a skin assessment.
Is IPL photorejuvenation effective for shrinking pores? Which type of enlarged pores is it suitable for?
IPL photorejuvenation stimulates the regeneration of collagen and elastic fibers through intense pulsed light and works well for enlarged pores caused by aging or skin laxity. It also improves skin with pigmentation and uneven tone, making it suitable for aging-type and mild inflammatory-type enlarged pores. People with sensitive or darker skin should proceed with caution after a physician's assessment.
Does squeezing comedones really make pores larger?
Improperly squeezing comedones causes mechanical damage to the follicle wall and triggers a local inflammatory reaction; after the inflammation subsides, pores may show dilation marks due to tissue damage. In addition, improper squeezing may push bacteria deeper into the skin, triggering more severe acne and further worsening pore problems.
What is the connection between sun protection and enlarged pores?
UV rays break down collagen and elastic fibers in the skin, weakening its supporting structure, so pores appear looser and more obvious because they lose the support of surrounding tissue. Long-term lack of sun protection accelerates the process of skin photoaging and is one of the important external factors that continually worsen enlarged pores.
How long does recovery take after a Hydrafacial (HIFU) treatment?
The recovery period after Hydrafacial (with HIFU) is relatively short; most people may experience mild redness and warmth after treatment, which usually resolves within a few hours to a day or two. After treatment, it is recommended to increase hydration and sun protection and avoid irritating skincare products. Specific aftercare advice should follow the guidance of the treating physician.
Where in Toronto or Markham can I find a Chinese-speaking physician to consult about medical aesthetic treatment for enlarged pores?
ID Cosmetic Clinic in Markham/Toronto is staffed by Dr. Dan Xu (MD, CCFP), who holds a Doctor of Medicine degree from Canada and a medical aesthetics license and provides bilingual English and Chinese services. The clinic offers personalized assessments for options such as skin booster injections, Hydrafacial and IPL for enlarged pores, and you can book a free consultation through the official channels.
Will enlarged pores keep getting worse with age?
In aging-type enlarged pores, as age increases the skin continues to lose collagen and elastic fibers, firmness declines, and the supporting structure around the pores weakens, so pores may indeed gradually become more obvious. Early intervention with hydration, sun protection and necessary medical aesthetic treatment can help slow this process, but specific results vary from person to person.
Is medical aesthetic treatment for enlarged pores suitable for all skin types?
Different medical aesthetic procedures have varying suitability for skin types — for example, IPL photorejuvenation requires careful assessment for people with darker skin, and people with sensitive skin need to rule out relevant contraindications before skin booster injections. Therefore, before any medical aesthetic treatment, a licensed physician should conduct a comprehensive assessment of skin type, health condition and treatment history to ensure safety and suitability.
