The reason why the color of the eyelid line is blurred

Under normal circumstances, the color of the contact lens will not fade. Generally speaking, the color blurring means that the contact lens looks like a caterpillar, which is a blurred contact lens. Color halo usually refers to the phenomenon that color blocks become larger and lighter when color enters the human body. The pigment remaining in the body causes the color blocks to become larger and lighter, forming a halo. Blooming is similar to fading, and is also a gradual process. So what are the reasons for discoloration?

Instantaneous color blurring refers to the phenomenon that the newly made lines become blurred within just a few seconds. In severe cases, it may even affect areas 2 cm away from the wound. Although the color is not very strong, it has a clear color difference from the flesh color. This kind of color blurring is most likely to occur when the doctor's technique is unprofessional. The reason is that the operator, worried about poor coloring, turns up the frequency of the machine and forces the needle deep into the skin. In addition, the manual speed is too slow or there are hesitations and pauses, causing a large amount of liquid pigment to be injected into the skin and merge into the numerous capillaries (tiny blood vessels), flowing everywhere with the blood. This phenomenon is particularly evident in individuals with thin skin and abundant capillaries.

Short-term color fading

This color blur is the most common and most difficult to overcome phenomenon in eyebrow operations, and it covers almost all tattoo line operations.

Normal contact lens tattooing techniques usually do not damage the subcutaneous tissue, so the exaggerated instantaneous color blur is unlikely to occur. But since it is traumatic pigmentation, it is difficult to avoid damaging the microvessels and lymphatic vessels in the dermis. Although the number and size of the microvessels and lymphatic vessels in the epidermis are smaller than those in the subcutaneous tissue, they still have their own destructive power on the physical properties of the pigment particles gathered there. At the same time, after the line operation is completed, the pigment particles are surrounded by the tissue cells where they are located. With the self-repair of the skin tissue and the body's rejection reaction, a part of them, together with the necrotic cells, form a scab (skin) along with platelets, lymph fluid, etc. and directly fall off the skin. After the wound heals, the combination of some pigment particles and tissue cells is still very fragile. The attack of phagocytes, the flushing of body fluids (including blood and lymph), the effect of rejection reaction, etc. will constantly damage those fragile links. The result of this destruction is that those unstable pigment particles, especially the small pigment particles, will constantly move away from their original positions and constantly combine with other tissue cells until they re-form a relatively strong combination. If these changes occur in the center of the color block, they may not be enough to cause visual difference. However, at the edge of the color block, when the number of pigment particles that leave their original position and diffuse toward the periphery of the color block reaches a certain degree, the color halo will appear.

The peak period of short-term color bleeding is often within half a year. Since most of the pigment particles that are pushed to the edge of the color block and cause the color bleeding are tiny particles, they are the preferred targets of attack by phagocytes. Therefore, this type of color bleeding disappears quickly. It is usually very light one year after recovery, and some can even be absorbed completely.

Long-term color fading

Long-term color bleeding refers to the color bleeding phenomenon that occurs slowly and lasts for a long time. Long-term color bleeding actually also includes short-term color bleeding, but the pigment particles diffused in the short term do not reach the basic amount for display. Old masters who have been in the industry for more than ten years should have a personal experience of this kind of color blur. The early old-style eyeliner is a typical example. At that time, the eyeliner pigments were basically large-grained pigments used for tattoos. The work done by craftsmen with higher technical levels would still be quite pleasing to the eye within one or two years, but would become rather worse after three or four years, and after five or six years, the lines would basically be invisible. In contrast to small-particle pigments, large-particle pigments have the advantages of large volume and mass. They can "implant" easily and form a relatively strong combination with tissue cells. They have a certain resistance to various destructive forces, will not easily move, and diffuse slowly. Furthermore, the human body's phagocytes are helpless against such large-particle pigments. After a certain period of time, the pigment particles will not change in number, so the color halo will continue, although it will become weaker as time goes by.

Of course, the plant pigments used in today’s contact lens liner will be naturally absorbed and metabolized by the human body, and the chance of long-term discoloration is very low, unless you choose a non-professional institution that uses unqualified pigments, which will cause long-term discoloration.
