14 Jan Dermatologist Discusses Removal of Black Dye From Henna Tattoos
MedicalResearch.com Interview with:
Karan Lal, DO, Marketing Committee Member
for the Society for Pediatric Dermatology,
Dermatologist at UMass Memorial Medical Center.
Dr. Lal discusses the recent study of a procedure to remove black dye from henna tattoos.
MedicalResearch.com: What is the background for this study?
Response: Para‐phenylenediamine, a dye frequently added to henna tattoos to create the black color, is a potent contact allergen. Severe contact dermatitis may arise within days even after the first application. Our objective was to develop a method for rapid and complete removal of para‐phenylenediamine‐containing black henna tattoos from the skin, an important problem many physicians are confronted with, but for which no simple method exists.
MedicalResearch.com: Where else is PPD found, ie hair dyes?
Response: PPD, known formally as para-phenylenediamine is a black dye found in black textiles/clothes, rubbers, hair dyes, and in black henna(not organic henna) tattoos. This study was based on successful removal of another type of phenylenediamine with a commonly used solvent called PEG-400.
MedicalResearch.com: Would you describe the PPD removal procedure? Does it require medical supervision?
Response: The procedure is simple. Cotton balls soaked in PEG-400 were dabbed on the tattoo areas without rubbing. This was done for a number of cycles separated by 5 min tap water wash cycles. Henna tattoos last up to 3 weeks. PEG-400 is not a toxic chemical but because this has not been widely performed I would still want a healthcare provider to perform the procedure.
MedicalResearch.com: What should readers take away from your report?
Response: Readers should know that black henna tattoos pose a risk for contact dermatitis for children and adults and that patients can be sensitized from other agents that have PPD.
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: It is exciting to hear about a non-surgical means of tattoo removal in the event an allergic reaction occurs. I would like to see a larger case series of patients with different skin tones to see if there is any risk of dyspigmentation from treatment.
