Pimples from stress
back to main page
"Stress pimples" is a colloquial term for skin changes that appear or worsen during periods of prolonged psychological tension. In dermatology, stress is considered an important factor that exacerbates many skin conditions, primarily acne vulgaris, folliculitis, and seborrheic dermatitis. This mechanism results from the effect of stress on the hormonal, immune, and nervous systems. In stressful situations the body produces increased amounts of hormones, especially cortisol, which can stimulate the sebaceous glands to produce more sebum and intensify inflammatory processes in the skin. As a result, inflammatory lesions appear—papules, pustules, or comedones—most often in areas with a high number of sebaceous glands.
Stress pimples – location
Skin changes related to stress most often appear in areas where there is a large number of sebaceous glands and where the skin is particularly sensitive to hormonal and inflammatory disturbances. In dermatology it is observed that stress can increase sebum production and disturb the keratinization of hair follicle openings, which leads to the formation of comedones and inflammatory lesions.
The most common locations of pustules related to stress are:
- the face, especially the forehead, nose and chin (the so-called T-zone),
- the jawline and lower cheeks, where changes of a hormonal nature often appear,
- the back, especially the upper back and shoulders,
- the chest,
- the scalp.
Lesions can have various morphological forms. Most commonly observed are:
- open and closed comedones,
- inflammatory papules,
- pustules,
- in more severe cases deeper inflammatory nodules.
The activation of the so-called hypothalamic–pituitary–adrenal (HPA) axis also plays an important role in the development of lesions. In response to stress, the body increases the production of stress hormones, primarily cortisol. This hormone affects the function of sebaceous glands and intensifies inflammatory processes in the skin. At the same time, epidermal regeneration is disturbed and the skin’s protective barrier is weakened.
Studies also point to the role of neuropeptides, such as substance P, which are released in the nerve endings of the skin in response to stress. These substances can stimulate sebaceous glands to produce sebum and intensify inflammatory reactions within hair follicles.
In clinical practice it is also important to differentiate stress-related lesions from other skin diseases, especially hormonal acne. Pustules that worsen under stress often appear suddenly during periods of increased psychological tension and may decrease after the stressor subsides. Hormonal acne, on the other hand, usually has a chronic character and is more often located in the lower part of the face – in the area of the chin, jawline and neck.
What to do about pimples from stress?
Treatment of pimples that worsen under the influence of stress should include both dermatological therapy and measures that reduce the impact of stressors on the body. In clinical practice, a combination of appropriate skin care, pharmacological treatment, and dermatological procedures is used.
The basis of therapy is regulation of sebaceous gland activity and reduction of skin inflammation. In topical treatment, preparations most commonly used contain:
- salicylic acid, which acts keratolytically and helps unclog hair follicle openings,
- topical retinoids, which regulate the keratinization of the epidermis and prevent the formation of comedones,
- azelaic acid, which has anti-inflammatory and antibacterial effects,
- niacinamide, which reduces sebum production and supports skin regeneration.
In cases of more severe lesions, a dermatologist may also apply pharmacological treatments such as:
- topical or systemic antibiotics, used for inflammatory lesions,
- oral retinoids, used in more severe forms of acne,
- treatments that regulate hormonal balance.
An important element of therapy is also reducing chronic stress, because prolonged psychological tension increases production of cortisol and inflammatory mediators in the body. As supportive measures, it is recommended:
- regular physical activity,
- an adequate amount of sleep,
- relaxation techniques and reduction of psychological tension,
- limiting substance use and highly processed foods.
Various dermatological and aesthetic medicine procedures are also used in the treatment of skin lesions, which help cleanse the skin and reduce inflammation. The most commonly used methods include:
- chemical peels, which exfoliate the epidermis and unclog sebaceous gland openings,
- laser treatments, supporting reduction of inflammatory lesions and regulating sebaceous gland activity,
- LED light therapies, which have anti-inflammatory and antibacterial effects,
- professional skin-cleansing procedures.
The effectiveness of treatment depends primarily on a comprehensive approach to the problem, because stress-related skin lesions result from the combined influence of dermatological, hormonal, and psychological factors.
