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
- 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.
Direct Answer
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:
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.
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.
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.
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.
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:
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.
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.
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.
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.
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.
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.
Medical Aesthetic Treatments for Enlarged Pores
- Skin booster injections:
- Principle: Skin booster injections deliver hyaluronic acid along with various vitamins, minerals, amino acids and other nutrients into the skin to achieve instant hydration, brighten skin tone and improve skin texture.
- Effect: Skin booster injections can quickly replenish a large amount of moisture in the skin, enhancing elasticity and firmness, thereby effectively improving enlarged pores.
- Procedure: Skin booster injections use microneedle technology to deliver a specific solution into the dermis, so there may be mild discomfort during the procedure, but the recovery period is relatively short.

Hydrafacial:
- Principle: Hydrafacial (with High-Intensity Focused Ultrasound, HIFU) is a method that uses high-intensity focused ultrasound technology to act on the deep layers of the skin and produce a coagulation effect.
- Effect: Through the thermal effect of high-intensity focused ultrasound, it can stimulate collagen regeneration in the dermis, thereby improving skin firmness and effectively shrinking pores.
- Procedure: During the procedure, clients may feel warmth and slight tingling in the skin, but overall it is safe with a short recovery period.

Photorejuvenation (IPL):
- Principle: Photorejuvenation uses intense pulsed light of specific wavelengths to perform photothermal treatment on the skin.
- Effect: Photorejuvenation can stimulate the regeneration of collagen and elastic fibers, improving the overall texture and tone of the skin and effectively shrinking pores.
- Procedure: During the procedure, clients may feel mild tingling and a sensation of heat, but the level of discomfort varies from person to person. After photorejuvenation, the skin may have mild redness, but it usually subsides naturally within a few hours to a few days.
