Background Despite the enormous increase in sunscreen use, allergic contact (AC) and photoallergic (PA) reactions to ultraviolet (UV) filters are considered rare.

TLDR
Whether photoallergic contact dermatitis is as uncommon as it is usually considered to be and to review the associated clinical features is reviewed.
Photoallergic contact dermatitis
Background: Photoallergic contact dermatitis (PACD) presents in patients after certain exogenous agents come into contact with the skin in the presence of ultraviolet and/or visible light. The best
A European multicentre photopatch test study
Background  The two most common agent groups currently responsible for photoallergic contact dermatitis (PACD) are organic ultraviolet (UV) absorbers in sunscreens and topical nonsteroidal
Causal agents of photoallergic contact dermatitis diagnosed in the national institute of dermatology of Colombia
TLDR
The photoallergens causing photoallergic contact dermatitis in the population attending the outpatient clinic of the Centro Dermatologico Federico Lleras Acosta and the National Institute of Dermatology of Colombia are described.
Photopatch tests: an Italian multicentre study from 2004 to 2006
Background:  Evaluation of possible photoallergic contact dermatitis in at‐risk populations is often not undertaken, and an agreed methodology for investigation is uncommonly used.
Ultraviolet filter, fragrance and preservative allergens in New Zealand sunscreens
TLDR
The aim of this study was to investigate contact allergens and photoallergens in sunscreens commercially sold on the shelves of supermarkets and pharmacies in New Zealand.
Sunscreen photopatch testing: a series of 157 children
TLDR
Photoprotection including sunscreen use in children is encouraged by health campaigns, but limited data are available in children and contact reactions in adults.
Sunscreen Allergy: A Review of Epidemiology, Clinical Characteristics, and Responsible Allergens
TLDR
The epidemiology and clinical characteristics of sunscreen allergy are summarized in this review and a detailed discussion of specific chemical sunscreen allergens is provided.
Photopatch tests: any news under the sun?
TLDR
The aim of the present study was to determine the incidence of photoallergic contact dermatitis in the centre and to identify common photoallergens, important for patient selection and formulation of the appropriate photopatch test series.

Investigation of photodermatosis is based primarily on the history and clinical findings, histological, immunological and biochemical findings are variably helpful depending on the clinical picture.

Persistence of allergic contact sensitivity in subjects with photosensitivity dermatitis and actinic reticuloid syndrome
TLDR
Positive patch test reactions were demonstrated some years after the initial diagnosis and after significant maintained improvement of the photodermatosis had occured.
Sunscreen sensitization: a 5-year study.
TLDR
Results, obtained from January 1990 to December 1994, confirm that, given the high frequency of photosensitization cases, a large part of the battery of photopatch tests should be dedicated to sunblocks.
Manual of Contact Dermatitis
Fregert'sManual of Contact Dermatitisis packed with useful information and is highly recommended as a primer for those learning dermatology and as a brief refresher text for the practicing clinician.
Photoallergy to benzophenone.
TLDR
The cases of four individuals with photoallergy to oxybenzone in sunscreens are reported, likely that such reactions will become more commonplace since oxyben Zone is by far the most frequently used agent in modern, high sun protection factor sun screens being marketed today.

Contact and photocontact sensitivity to sunscreens
TLDR
Clinicians should consider contact and photocontact allergy, especially in patients with photodermatoses and photo‐aggravated dermatoses and they should perform photopatch testing, and patients must be warned to avoid products containing the (photo)allergen.
Contact and photocontact sensitization in chronic actinic dermatitis: sesquiterpene lactone mix is an important allergen
TLDR
The association between Compositae (sesquiterpene lactone) dermatitis and CAD is confirmed, with neither detectable contact nor photocontact allergy, nor a preceding history of endogenous eczema.
Contact and photocontact allergy in persistent light reactivity
TLDR
In 13 of the 16 patients in whom a biopsy was carried out, the histology supported the clinical diagnosis, and in none of the biopsies was the picture diagnostic in itself, underlines the inadequacy of light microscopy as the only diagnostic procedure.
The Scandinavian multicenter photopatch study 1980-1985: final report.
TLDR
The principal photoallergens and contact allergens in the PLE, persistent light reaction and actinic reticuloid groups are discussed, together with the problems, risks and possible mechanisms of induction of photosensitization in patients with suspected photodermatosis.
