Temporary stickers, popular especially with children, can damage the skin barrier that protects the skin .
So much so that the skin with temporary tattoos has a lower temperature, less hydration and worse antioxidant capacity than those with permanent tattoos.
This is what states a study published in the Journal of Clinical Medicine developed by a team of researchers from the University of Granada (UGR).
DRASTIC LOSS OF HYDRATION IN THE SKIN
Research has analyzed the dermatological effects of permanent tattoos, performed with needles on the skin, and adhesive temporary tattoos.
In total, this study included the analysis of 67 samples , 34 permanent tattoos, and 33 adhesives.
And the results are surprising: the levels of skin hydration loss were higher in adhesive tattoos.
This loss is an indicator that there is a certain degree of damage to the epidermal barrier of the skin, that is, the one that functions as a defense of the organ.
For this reason, adhesive tattoos should be used with caution , especially in patients who already have some damage to their skin, such as those with psoriasis or atopic dermatitis.
This study has added a new component to the scientific literature, since most adverse reactions related to tattoos are associated with permanent ones.
In this case, they are usually due to problems of an infectious , granulomatous or allergic nature, in relation to the pigments used or the tattooing process.
In addition, other temporary tattoos such as henna , which are not analyzed in this study, have been associated with a large number of allergic reactions.
PERMANENT TATTOOING RESPECTS THE EPIDERMAL BARRIER
On the other hand, regarding the effects caused by permanent tattoos, the traumatic process of tattooing is pointed out, capable of causing adverse skin reactions .
Of course, permanently tattooed skin does not differ significantly from non-tattooed skin , according to research.
“We concluded in the work that permanent tattoos do not seem to significantly affect the epidermal barrier function , something that adhesives do,” explained José Pablo Serrano, one of the authors of the study, on the university’s website .
However, since the tattooing process is traumatic and not without complications, the recommendation is to exercise caution before getting any tattoo.
Information about the possible infectious or allergic risks that the tattooed person can produce is essential.
As a general recommendation, it has been observed that red ink produces more inflammation in the long term due to the type of dye used, so it is highly recommended to do without it.
Likewise, you should go to salons that offer quality and hygiene standards that minimize these risks.
Other tips can be from not tattooing over the moles , since, although they are benign lesions, they could change at some point and the ink greatly conditions their follow-up.
Even choosing fall or winter to get the tattoo since it is still a wound prone to infection.
In this way, in the summer season, being more in contact with the water of beaches and swimming pools, complications could arise .
Once the tattoo has been made under all the safety recommendations, it is also important to continue taking care of the skin.

As soon as it is finished, the tattoo artist will protect it with petroleum jelly and bandage it. A few hours later the dressing should be removed and washed carefully with hypoallergenic soap and water.
During the next seven or ten days hygiene will be the most important thing. It should be washed with neutral soap and applied healing ointment three or four times a day.
At this time, it is important to avoid abrasions caused by clothing or footwear, direct sunlight or sea water.
After this first healing period, we just have to make sure that we keep the tattoo clean and hydrated with normal hygiene.
Although it must be borne in mind that laser hair removal is discouraged in the area of the tattoo and the surroundings because it causes burns.
