Uneven skin texture and discolouration are common concerns, but many individuals may not know what’s causing them. Is it a scar, a fading mark, or enlarged pores? Understanding the difference can help guide your skincare choices and determine when professional input may be helpful.
Drawing on his clinical experience, Dr Justin Boey shares an overview of how procedures such as lasers, microneedling, dermal fillers, and chemical peels are used in the medical management of common skin concerns.
In this article, you’ll learn how to identify acne scars, dark marks, and enlarged pores, visually and by texture. We’ll also cover their common causes and when it may be appropriate to seek medical advice.
Understanding the Key Skin Conditions
Understanding whether you’re dealing with acne scars, post-inflammatory marks, or enlarged pores can guide you towards more suitable treatment options. Here’s a simple breakdown of each.
What Acne Scars Are
Acne scars refer to textural changes in the skin that remain after significant breakouts. They develop when deep inflammation damages the skin, leading to collagen loss, an essential protein that helps the skin heal and remain firm.
There are several types of acne scars:
- Ice pick scars: Deep and narrow, like small puncture marks.
- Rolling scars: Wide depressions with sloping edges, giving skin a wavy look.
- Boxcar scars: Broad, box-like depressions with defined edges.
- Hypertrophic scars: Raised, thicker scars caused by excess collagen during healing.
These scars don’t fade on their own and often require professional treatments to improve their appearance.
What Dark Marks Mean (Post-Inflammatory Hyperpigmentation or Erythema)
Dark marks are flat spots that remain after a pimple heals, but they’re not scars. They result from inflammation, which triggers melanin production or increased blood flow, depending on your skin type.
They typically appear as:
- Brown marks (more common in deeper skin tones)
- Red or pink spots (more common in lighter skin tones)
- Purple marks (in some transitional healing stages)
Unlike acne scars, these marks are temporary. With time, sun protection, and good skincare, they usually fade on their own, though the process can take weeks to months.
What Enlarged Pores Are
Enlarged pores are visible openings in the skin’s hair follicles, especially in oilier areas such as the T-zone (forehead, nose, and chin). They’re not a result of scarring or inflammation, but are influenced by:
- Excess oil production
- Reduced skin elasticity
- Genetic factors
They may appear more noticeable:
- Under certain lighting conditions
- When skin is oily or congested
- After makeup application, especially without a proper primer
Unlike acne scars or dark marks, enlarged pores are a natural skin feature, though their appearance can be managed with consistent skincare.
Visual and Texture-Based Clues
To understand what you’re dealing with, start by observing how your skin looks and feels. Texture, colour, and shape offer helpful clues that can point you in the right direction. With the right tools, such as soft lighting or an angled mirror, you can spot differences that aren’t obvious in bright, overhead lighting.
Flat vs Textured: Use of Light and Touch
The texture of your skin can be a key indicator of what’s going on beneath the surface:
- Flat discolouration: Likely a dark mark—either post-inflammatory hyperpigmentation (brown) or erythema (red). These spots don’t have a raised or indented feel.
- Indented or raised areas: Often acne scars. These can feel uneven to the touch and become more visible under angled lighting.
- Round, open dots: These are typically enlarged pores, especially when they cluster in oilier areas like the nose or forehead.
Tip: Use soft lighting or an angled mirror to highlight textural changes. Shadows will often reveal what flat, frontal lighting hides.
Colour Indicators
Colour differences can further help identify what type of skin concern you’re dealing with:
- Red marks: Often signal post-inflammatory erythema, a form of temporary redness that appears after inflammation has subsided.
- Brown or grey spots: These suggest post-inflammatory hyperpigmentation, which is more common in medium to deep skin tones.
- No colour, just uneven texture: Most likely a scar, as textural acne scars don’t typically carry strong pigmentation.
Location Matters
Where the irregularity appears can also offer insight:
- Cheeks and jawline: These are common areas for acne scars, especially after persistent or cystic acne.
- T-zone (forehead, nose, chin): Often features enlarged pores due to increased oil activity.
- Chin and upper cheeks: Prone to dark marks, especially after hormonal breakouts, which tend to occur in these zones.
Understanding these patterns can help you match the right treatment or know when to seek guidance from a medical provider.
Root Causes Behind Each Skin Issue
Each condition has distinct triggers, often influenced by both physiological factors and lifestyle habits.
What Causes Acne Scars
Acne scars form when inflammation from deeper breakouts damages the skin’s supporting structure. Instead of smooth healing, the skin struggles to repair itself properly, especially when healing is delayed.
Key triggers include:
- Inflammation from cystic or nodular acne
- Delayed healing, often from repeated breakouts in the same area
- Picking or squeezing pimples, worsening tissue damage
- Loss of collagen during recovery, leading to sunken or raised scars
What Causes Dark Marks
Dark marks, also called post-inflammatory hyperpigmentation (PIH) or erythema, develop after acne or injury causes the skin to overproduce melanin (pigment) or triggers increased blood flow.
Common contributors:
- Skin trauma from breakouts, scratching, or harsh treatments
- Melanin overproduction during the skin’s natural healing process
- Higher risk in medium to deeper skin tones, where pigment cells are more reactive
These marks aren’t permanent but can take time to fade, particularly without sun protection.
What Causes Enlarged Pores
Enlarged pores result from structural and functional changes in the skin, often related to oil production and ageing.
Main causes include:
- Excess oil or sebum production, which stretches the pore openings
- Genetics, as some individuals naturally have larger pores
- Ageing, which reduces skin elasticity and makes pores appear more prominent
- Sun exposure, which accelerates collagen breakdown and weakens pore structure
While you can’t eliminate pores, managing these factors can help minimise their appearance.
Self-Assessment Checklist
Use this quick reference table to help you identify whether you’re dealing with acne scars, dark marks, or enlarged pores.
| Feature | Acne Scar | Dark Mark (PIH) | Enlarged Pore |
|---|---|---|---|
| Texture | Indented or raised | Smooth | Slightly indented dot |
| Colour | Skin-coloured or red | Brown, red, or purple | Matches skin tone |
| Permanency | Permanent without treatment | Temporary (fades) | Ongoing but manageable |
| Cause | Inflammation + trauma | Post-acne pigmentation | Oil, genetics, age |
| Treatment Needed | Professional intervention | Topicals, fading creams | Pore-refining skincare |
If you notice features that align with permanent texture changes or persistent discolouration, it may be time to speak with a qualified aesthetic professional for personalised advice and treatment options.
When to See a Dermatologist
While many skin concerns can be managed at home with consistent skincare, there are times when professional help is necessary. Seeking a medical opinion early can also prevent certain conditions from worsening over time.
Consider seeing a dermatologist if:
- Scars are deep, widespread, or don’t improve with over-the-counter treatments
- Dark marks have persisted for more than six months without fading.
- Pores have suddenly become larger or are worsening despite a stable routine.
Recognising the type of skin concern you’re dealing with is the first step. But for many, understanding what it is isn’t the same as knowing what to do next. When home care isn’t enough or changes feel stagnant, clinical treatments can offer more targeted support.
Clinical Treatments by Skin Issue
Each skin concern responds differently to various treatments. Here’s a breakdown of commonly used procedures matched to acne scars, dark marks, and enlarged pores.
These in-clinic procedures are designed to address specific concerns based on skin type, severity, and cause, often using tools and techniques not available through at-home skincare. The following section outlines common treatment options used in medical settings and how they are matched to each skin issue.
For Acne Scars
Medical procedures for acne scars are designed to improve overall skin texture by supporting collagen production or addressing surface irregularities.
- Microneedling: Uses fine needles to trigger collagen production and improve skin structure
- Pico Laser: Target pigmentation and superficial scarring, with minimal disruption to surrounding tissue.
- Fractional Laser: Treats sections of the skin to encourage skin renewal, which may benefit individuals with deeper scarring.
- TCA Cross: A high-strength chemical peel technique ideal for ice pick scars to induce remodelling within the skin.
- Subcision: A minor surgical procedure that aims to release fibrous bands beneath tethered scars, such as rolling scars, to improve skin contour.
For Dark Marks
Post-acne dark marks, including pigmentation and redness, can be managed with treatments that focus on promoting skin renewal and reducing melanin or inflammation.
- Pico Laser: Breaks down excess melanin in targeted areas, which may help lighten post-inflammatory pigmentation.
- Chemical Peels (AHA/BHA): These acids promote exfoliation and skin cell turnover, which can assist in the gradual fading of pigmented spots.
- Topical Lightening Agents: Prescription creams, such as those containing hydroquinone or azelaic acid, can help regulate melanin production and support uniform skin tone.
- LED Therapy: Uses specific wavelengths of light to support skin healing and may help reduce redness caused by inflammation.
For Enlarged Pores
Enlarged pores may be influenced by skin type, oil production, and ageing. Treatments aim to support skin firmness and improve overall texture.
- Microneedling with Radiofrequency (RF): Combines mechanical stimulation with heat energy to support skin tightening and improve the appearance of pores.
- Laser Resurfacing: Encourages collagen stimulation within the skin, resulting in a smoother texture and a more refined pore appearance.
- Prescription Retinoids: Topical retinoids can help regulate skin cell turnover and sebum production, ultimately contributing to a more balanced skin appearance over time.
- Botulinum Toxin (off-label use): In certain cases, this treatment may be used to reduce oil production in targeted areas, potentially reducing the appearance of pores.
