Because of how light they are, white inks tend to be the first to fade as a tattoo ages. For this reason, you need to be aware of this before getting your tattoo that may be completely faded with only residual lines and scars 20 years down the line.
Beside above, why white ink tattoos are a bad idea?
Squires explains that it takes multiple passes to get white ink to show up under the skin — which is perhaps why white tattoos have a reputation for being more painful. White tattoos also fade quicker than regular tattoos and may yellow over time as the ink is broken down by the body.
Just so, do white tattoos turn yellow?
White ink tattoos are becoming more popular but keep in mind white ink is prone to turning yellow, especially when exposed to sunlight too soon and prolonged sun exposure without any skin protection can cause a color change over time (it also depends on the inks).
