Getting a henna tattoo is also a choice that can put your health at risk because, just like in the black ink of the definitive tattoo, in the case of black henna, signs and symptoms of allergy can also appear, such as:
Itching, redness, blemish, blisters or discoloration of the skin at the tattoo site;
Red spots can spread throughout the body that usually appear within 12 days.
In this case, one should go to the dermatologist to start the treatment, which consists of removing the tattoo and applying creams and lotions such as corticosteroids on the spot. After the allergy is resolved, the henna tattoo site may be permanently marked, in high relief, or the skin may be lighter or darker throughout the outline of the design.
Is henna tattoo a natural substance?
Henna is a dye from a plant called Lawsonia inermis sp, which after being dried is reduced to powder. This powder is mixed with a paste that allows a better application of the product on the skin, having a color closer to brown. Thus, henna tattoos are generally more natural and therefore have a lower risk of allergic reaction.
However, to achieve a black henna color, other substances are added, such as synthetic paraphenylenediamine dye (PPD). The darker the color, the more additives the paint contains and, therefore, the greater the risk of allergies because it can no longer be considered a natural product.
Thus, the tattoos that have less risk to health are the natural henna tattoos, which have a color closer to brown, with a slight reddish hue and which are the tattoos made by indigenous tribes, for example. However, these are not definitive and need to be touched up over time.
