TLDR Various substances, including cosmetic sponges, vein glue, chai tea, skincare products, and medicaments, can cause allergic contact dermatitis, and healthcare workers often react to N95 masks.
The document discusses five cases of allergic contact dermatitis (ACD) caused by various substances such as a rubber-based cosmetic sponge, n-butyl-2-cyanoacrylate in VenaBlock vein glue, cinnamon in chai tea, ethylhexylglycerin in skincare products, and multiple allergens in topical medicaments. It also includes a study showing that over 80% of healthcare workers reported skin reactions from N95 mask use, particularly the 3M Aura Respirator mask. The document also explores the link between contact sensitisation, ACD, and frontal fibrosing alopecia (FFA), a chronic scarring alopecia often associated with androgenetic alopecia and hypothyroidism. It suggests that FFA may be linked to increased contact sensitisation and ACD to certain allergens found in fragrances, methylisothiazolinone/methylchloroisothiazolinone, benzyl salicylate, and topical agents like moisturisers and sunscreens.
