Summary
Temporary henna tattoos, often sought by tourists, can cause allergic reactions. The chemical para-phenylenediamine, added for black color, is a common sensitizer, posing risks despite henna
Area of Science:
- Dermatology
- Toxicology
- Public Health
Background:
- Temporary henna tattoos are popular, especially among tourists in exotic destinations.
- Hypersensitivity to natural henna is rare, but additives can cause issues.
- Para-phenylenediamine (PPD) is frequently added to achieve a blackish hue.
Purpose of the Study:
- To review existing literature on allergic reactions to temporary henna tattoos.
- To outline the causes, clinical presentations, and potential complications.
- To highlight that these tattoos are not risk-free.
Main Methods:
- Literature review of scientific articles and case reports.
- Analysis of studies focusing on adverse reactions to henna tattoos.
- Synthesis of information regarding PPD sensitization.
Main Results:
- Para-phenylenediamine (PPD) is a common contact sensitizer.
- Allergic reactions to temporary henna tattoos are linked to PPD exposure.
- Clinical manifestations include contact dermatitis and other hypersensitivity reactions.
Conclusions:
- Temporary henna tattoos, especially those with PPD, pose a significant risk of allergic contact dermatitis.
- Consumers should be aware of the potential dangers associated with black henna tattoos.
- Healthcare providers should consider PPD allergy in patients presenting with dermatitis after tattoo application.

01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...

01:29Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
01:30Hypersensitivities
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
