Summary
Topical retinoids are a cornerstone of acne treatment, recommended for most acne types. Combination therapies, including fixed-product formulations, offer improved adherence and outcomes by targeting multiple acne causes.
Area of Science:
- Dermatology
- Pharmacology
Background:
- Vitamin A derivatives (retinoids) have impacted epidermal proliferation since 1949.
- Topical tretinoin was approved in 1971, with subsequent formulation improvements.
- Receptor-selective retinoids like adapalene and tazarotene were developed.
Purpose of the Study:
- To review the evolution and current role of topical retinoids in acne therapy.
- To highlight the benefits of combination therapies and fixed-product formulations.
Main Methods:
- Review of historical data and current clinical recommendations for topical retinoids.
- Analysis of treatment strategies for various acne severities and types.
Main Results:
- Topical retinoids are first-line therapy for most acne, except severe forms.
- Combination therapy with benzoyl peroxide and antibiotics is recommended for inflammatory acne.
- Fixed-combination products improve adherence and outcomes by targeting multiple pathogenic factors.
Conclusions:
- Topical retinoids are essential in acne management, used in monotherapy or combination.
- Combination therapy addresses abnormal keratinization, P. acnes, inflammation, and sebum.
- Fixed-combination products enhance patient adherence and treatment effectiveness.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:22Behavior Therapy
Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.

01:28Drug Therapy
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
