Social media influenced self-application of cyanoacrylate for double chin reduction in an adolescent girl: an unusual case of post-inflammatory hyperpigmentation

IntroductionCyanoacrylate, used as a topical adhesive for wound closure in clinical settings, can result in poor cosmetic outcome on application to skin. Lack of formal medical or dermatological training among social media influencers poses risks of improper diagnosis, incorrect treatments, ineffective home remedies, and potential self-injury or long-term skin effects, especially among adolescents.Case presentationThe authors present a case of a young girl with a persistent post-inflammatory hyperpigmentation after using cyanoacrylate on her chin as a home remedy to reduce her double chin problem after learning from a video on social media. Biopsy findings were consistent with post-inflammatory hyperpigmentation in dermis.Clinical discussionApplication of cyanoacrylate over skin can result in allergic reactions, burn injuries, infections, itching, skin blistering, and aesthetic issues. Persistent post-inflammatory hyperpigmentation can be a poor cosmetic outcome on application of cyanoacrylate over skin.ConclusionInadequate social media safety regulations require healthcare professionals to be aware of social trends among adolescents and to encourage them for open conversations and professional help-seeking during times of distress in this digital era.
