Pores are small openings in the outermost layer of the skin that release oils and sweat. Many people seek treatment from a dermatologist because their pores are undesirably large, causing embarrassment and a lack of confidence in their appearance. If enlarged pores are a concern for you, there are a variety of at-home and clinic-based treatments that can make your pores less noticeable.
Pores are small openings in the skin that allow sweat and natural oils (sebum) to reach the surface. These openings play a vital role in regulating body temperature and maintaining skin hydration. While everyone has pores, their size and visibility can vary from person to person. In some cases, pores may appear enlarged, giving the skin a rough or uneven texture.
Enlarged pores are most noticeable in areas with higher concentrations of oil glands, such as the forehead, nose, cheeks, and chin — often referred to as the T-zone.
Pore size is primarily influenced by genetics, but several other factors can make them appear larger over time:
Excess Sebum (Oil) Production
When oil builds up in the pores, it can mix with dead skin cells and debris, stretching the pore and making it more visible on the surface.
Loss of Skin Elasticity
As collagen and elastin levels decrease with age or sun exposure, the skin around the pores may begin to sag, causing pores to appear wider.
Sun Damage
Prolonged UV exposure breaks down collagen — a key structural protein in the skin — leading to loss of firmness and increased pore visibility.
Clogged Pores or Congestion
Debris within the pore can expand it over time, especially if not regularly cleared through gentle exfoliation or appropriate skincare.
Skin Type
Individuals with oily or combination skin tend to have more noticeable pores due to increased sebum activity.
Pores cannot be “shrunk” or removed, but their appearance can often be minimised through a combination of skincare and in-clinic treatments. Results vary depending on the cause of pore enlargement, skin type, and overall condition.
At Northside Dermatology, consulting doctors may recommend evidence-based treatment options to improve skin texture and support healthy pore function. These may include:
HydraFacial – to deeply cleanse, exfoliate, and hydrate the skin
Chemical Peels – to remove dead skin cells and encourage smoother skin
NanoFractional Radiofrequency – to remodel skin and stimulate collagen
Laser Resurfacing (e.g., CO₂ laser) – to refine texture and support long-term improvement
Topical or prescription skincare – where appropriate, based on clinical assessment
Treatment plans are tailored to individual needs following consultation with a qualified doctor.
A range of treatment options are available to help improve skin texture and minimise the appearance of enlarged pores, tailored to your skin type and concerns.
Pore size is largely determined by genetics – some people are born with prominent pores, others are born with pores that are barely visible. Enlarged pores are most common in areas that are sebaceous (oily), like the nose and the upper lip. Individuals with acne or oily skin, particularly those who have a history of squeezing their pimples, are likely to have large pores. Some ethnicities also tend to have a naturally larger pore size.
Successful management of large pores starts with your skincare routine, the dermatologists recommend:
Prescription topical vitamin A cream can be beneficial in treating large pores. Oral vitamin A medication, which is primarily prescribed for acne and excessively oily skin, may also help reduce pore size.
There are many in-office treatments available for minimising large pores. A dermatologist will select the most appropriate option for you based on the severity of the condition and your cosmetic goals.
Treatments for mildly enlarged pores:
Treatments for more prominent pores:
TCA CROSS is the treatment of choice for deep pores. TCA works by creating a chemical reaction that leads to the formation of new collagen fibres that increase the height of the treated pores. Each TCA procedure can increase the height of an open pore by 20-40 percent. For optimal results, most patients need two to three procedures followed by RF resurfacing or CO2 resurfacing.
The TCA CROSS procedure involves depositing small amounts of TCA directly into enlarged pores. After cleansing your skin, your dermatologist will coat an applicator in TCA and apply the TCA to the base of a deep pore. The applicator is left in place until the surface of the skin in the treated area turns white (‘frosting’). The process is then repeated as appropriate to treat each remaining pore individually. On completion of the procedure, a topical emollient is applied to soothe the skin. TCA CROSS only treats the pores and spares the surrounding skin.
TCA CROSS is slightly uncomfortable but it is not painful. The procedure can be likened to the sensation of nettle stings or small ant bites, and is over within minutes.
Frosting of a treated pore will continue for up to 12 hours following a TCA CROSS procedure. The surrounding skin will be red for three to four days. Several days after treatment, a small scab will develop and shed. Do not pick at the scab; allow it to fall off naturally and let the healing process proceed at its own pace. Full recovery from a TCA CROSS procedure is expected within five to seven days. The dermatologists recommend applying a hydrating emollient and strict sun protection during the recovery period.
Yes, there’s always a chance of recurrence, especially if you have a history of sun damage. Regular follow-up checks are important to monitor your skin and catch any new or recurring spots early.
Protect your skin daily by using sunscreen, wearing protective clothing, avoiding tanning beds, and seeking shade during peak sun hours. Regular skin checks, both at home and with a dermatologist, are also key to prevention.
