Acne is a multifaceted skin condition that can present in various forms, and not all acne looks or behaves the same. Comedonal acne is a specific type characterized by non-inflammatory bumps, often appearing as stubborn “clogged pores” on the skin. This form of acne can affect self-confidence and, if untreated, may progress to more severe inflammatory lesions.
For medical aesthetic clinics and their clients, understanding what comedonal acne is, what causes it, and how to treat it can greatly improve skin health and satisfaction with care.
Comedonal acne is the result of blocked hair follicles within the skin, leading to the formation of comedones—small, flesh-colored, white, or dark bumps. Unlike inflamed pimples, comedonal acne does not typically present with redness, pus, or pain at first.

Closed comedones are tiny, raised bumps that form when dead skin cells, oil (sebum), and debris clog a hair follicle and become trapped beneath the outer layer of skin. They are usually not inflamed but may feel rough or bumpy and can cluster together, creating uneven texture. Without intervention, closed comedones can persist for weeks or months and sometimes progress to inflamed acne lesions if bacteria (Propionibacterium acnes) invade.
Multiple internal and external factors contribute to the development of comedonal acne:
1. Excess Oil Production
The sebaceous glands produce too much sebum, which combines with dead skin and clogs pores.
2. Abnormal Skin Cell Shedding (Keratinization)
Skin cells that line the follicles are shed irregularly, leading to accumulation in the pore.
3. Hormonal Changes
Adolescence, menstrual cycles, pregnancy, and the use of certain hormonal contraceptives can all increase oil production, triggering comedones
4. Cosmetics and Skincare (Comedogenic Products)
Use of oily, greasy, or pore-clogging (“comedogenic”) products can leave residues that block hair follicles. Common offenders include certain makeup, sunscreens, moisturizers, and hair products.
5. Genetics
A family history of acne increases the likelihood of developing comedonal acne.
6. Lifestyle Factors
1. Retinoids (Vitamin A Derivatives)
Examples: Adapalene (Differin), tretinoin, tazarotene
Action: Normalize skin cell turnover, discourage clogging of pores, and help open existing comedones.
Usage: Start with a lower concentration to reduce irritation, and apply at night.
2. Benzoyl Peroxide
Although more effective for inflammatory acne, it can help keep pores clear and reduce new comedone formation.
3. Salicylic Acid (Beta Hydroxy Acid)
Penetrates oil and helps exfoliate inside the pores, loosening dead skin and sebum.
Found in over-the-counter cleansers, toners, and spot treatments.
4. Azelaic Acid
Reduces clogged pores, has mild exfoliating and antibacterial properties. It is well-tolerated by sensitive skin.
1. Chemical Peels
Glycolic acid, lactic acid, or salicylic acid peels administered by trained professionals can help remove surface debris and stimulate renewal.
2. Manual Extraction
In-office comedone extraction may be performed for stubborn or numerous lesions, minimizing trauma and scarring.
3. Oral Medications
For widespread, treatment-resistant comedonal acne, oral retinoids (e.g., isotretinoin) or hormonal treatments may be considered under medical supervision.
Non-comedogenic Products: Choose makeup and skincare labeled as “non-comedogenic.”
Gentle Cleansing: Twice daily with a mild, pH-balanced cleanser.
Avoid Picking: Picking or squeezing can introduce bacteria and lead to inflammation or scarring.
Regular Exfoliation: Gentle exfoliation (chemical, not physical) can prevent buildup.
Consistent Routine: Results often take weeks to months; a reminder that patience is key.
Comedonal acne is a very common and often frustrating skin condition, but evidence-based topical therapies, professional treatments, and the right skincare can significantly improve its appearance.
Medical aesthetic clinics play a vital role in diagnosing different types of acne, recommending effective treatments, and empowering clients to maintain clear, healthy skin over the long term.
