A Common Problem: Dissatisfaction
A common problem that may develop with tattoos is the desire to remove them. Rremoving tattoos and permanent makeup can be very difficult.
Even if tattoos may be satisfactory at first, they sometimes fade.
If the tattooist injects the pigments too deeply into the skin, the pigments may migrate beyond the original sites, resulting in a blurred appearance.
Another reason of dissatisfaction is that the human body changes over time, and styles change with the season. Permanent makeup that may have looked flattering when first injected may later clash with changing skin tones and facial or body contours.
Some people who plan to have facial cosmetic surgery are advised that the appearance of their permanent makeup may become distorted. The tattoo seemed stylish at first may become dated and embarrassing. Changing tattoos or permanent makeup is not as easy as changing your mind.
You should consult your healthcare provider about the best removal techniques for you.
What About Temporary Tattoos?
Temporary tattoos, such as those applied to the skin with a moistened wad of cotton, fade several days after application. Most tattoos contain color additives approved for cosmetic use on the skin. Nevertheless, the agency has issued an import alert for certain foreign-made temporary tattoos.
Temporary tattoos subject to the import alert are not allowed into the United States because they don't carry the FDA-mandated ingredient labels or they contain colors not permitted by FDA for use in cosmetics applied to the skin. FDA received reports of allergic reactions to temporary tattoos.
In a analogous action, FDA has issued an import alert for henna intended for use on the skin. Thus henna is approved only for use as a hair dye, not for direct application to the skin.
Also, henna characteristically produces a reddish brown tint, raising questions about what ingredients are added to produce the varieties of colors labeled as "henna," such as "black henna" and "blue henna."
FDA also received reports of allergic reactions to products applied to the skin that contain henna.
