Introduction Topical corticosteroids are among the most commonly used medications in dermatology due to their high effectiveness in reducing inflammation, itching, and immune responses. However, the improper or unsupervised use of these medications has become a widespread issue, especially in communities where such products are available without adequate medical regulation. Misuse of topical corticosteroids—whether in terms of duration, potency, or application site—can lead to serious skin complications, sometimes more complex than the original condition. This issue represents a significant challenge in aesthetic medicine due to its direct impact on skin quality and appearance. Mechanism of Action of Topical Corticosteroids Corticosteroids work through several biological mechanisms, including: Suppression of the immune response Reduction of inflammatory mediators (cytokines) Decrease in blood vessel dilation Inhibition of cell proliferation These effects make them effective in treating conditions such as eczema and psoriasis, but they are also responsible for side effects when misused. Patterns of Misuse Misuse of corticosteroids includes: Long-term use without medical supervision Using high-potency preparations on the face Use for cosmetic purposes such as skin lightening Use of mixtures containing unknown corticosteroid concentrations Sudden discontinuation after prolonged use (steroid withdrawal) Dermatological Effects of Topical Corticosteroids Skin Atrophy One of the most common side effects, caused by: Reduced collagen production Dermal thinning Increased skin fragility Telangiectasia Occurs due to the effect of corticosteroids on blood vessel walls, leading to visible small vessels, especially on the face. Steroid Acne Results from: Increased sebum production Pore blockage Altered bacterial environment It is characterized by the sudden appearance of uniform acne lesions. Skin Pigmentation Disorders Corticosteroids may cause: Post-inflammatory hyperpigmentation Or hypopigmentation in some cases Perioral Dermatitis A common complication, particularly when corticosteroids are used on the face. Delayed Wound Healing Due to suppression of the immune response and reduced cell proliferation. Systemic Effects (in Severe Cases) With excessive use or application over large areas, systemic absorption may occur, leading to: Suppression of the hypothalamic–pituitary–adrenal (HPA) axis Hormonal disturbances (Though this is rare with moderate topical use) Corticosteroids in Aesthetics: A Common Issue In aesthetic practice, corticosteroids are often used in: Skin-lightening mixtures Unlicensed creams Traditional or homemade remedies This leads to temporary results (rapid lightening), followed by: Severe skin deterioration Worse pigmentation Skin dependence on corticosteroids Management of Misuse Cases Gradual Discontinuation Avoid sudden withdrawal to prevent rebound effects. Skin Barrier Repair Using: Moisturizers Barrier-repair products Treatment of Complications Anti-acne treatments Pigmentation therapy Anti-inflammatory treatments Education Raising patient awareness about the risks of improper use. Prevention Use corticosteroids only with a medical prescription Choose the appropriate potency Limit duration of use Avoid prolonged use on the face Do not use unknown mixtures Conclusion Topical corticosteroids are highly effective when used correctly, but they can become a significant source of harm when misused. In dermatological and aesthetic practice, medical awareness and patient education are essential to reducing this problem and ensuring safe and effective treatment outcomes. epared by: Assistant Lecturer Hussein Safaa Abdul Amir AL_mustaqbal University is the first university in Iraq
