Let’s figure out why, after some time, the color turned into cold gray-blue-violet shades?
Remember that our skin consists of 4 layers of epidermis, 2 layers of dermis and hypodermis.
The thickness of the epidermis is approximately 0,07-0,12 mm (this is the thickness of a paper sheet). The epidermis consists of dead cells, which are replaced by new ones. During a lifetime, we shed about 18 kg of skin with keratinized cells. Therefore, if you put the pigment in the dermis, nothing will remain there after healing. The time for complete healing can be estimated by adding 10 days to the person’s age.
In the case of permanent makeup, the pigment must enter the dermis. Moreover, as superficially as possible in the papillary layer, the color will then be “alive” and simply gets lighter over time, without turning into fancy shades. The papillary layer also renews but much slower than epidermis, and pigment slowly rises into the epidermis, and then gradually removed, and after 1-3 years we can safely renew the color.
If we get onto the reticular layer of the dermis, we will get a cold shade of color. The pigment is encapsulated and then goes down. It will be very difficult to remove it without scarring.
If pigments get into hypodermis, we can get a violet color, and most probably pigment will stick there forever.
According to the Tyndall effect, when light passes through an inhomogeneous substance (and our skin is extremely inhomogeneous), short wavelengths (blue-violet-blue spectrum) are primarily reflected. The layers of the skin are not homogeneous for light, and part of the light waves has time to reflect from these translucent structures and get into our eyes. This “tints” our visual perception. We see the color distorted, in a cold tone, besides the skin color itself is very important (our skin is like a prism, the darker skin, the thicker, the colder the permanent makeup will look).
Nothing happens to the pigment itself. It was, for example, brown, and remained so.
Therefore, tattoos are implemented too deep, into the hypodermis, giving a bluish tint.
