WHY DO EYEBROWS TURN INTO ASOLID GREY?

Most of us know someone who had their eyebrows tattooed and ended up, months or years later, with a blurry, overly saturated, or grayish appearance. While many people assume thisis simply the pigment “changing color,” that’s only part of the story.

In reality, the final appearance is largely influenced by how deep the pigment is implanted and how much pigment is deposited into the skin. These two factors have a significant impact not only on how the color heals initially but also on how it ages over time.

In most cases, that dark gray or bluish appearance is caused by excessive implantation depth, pigment oversaturation, or a combination of both.

One of the most common causes of oversaturation is performing maintenance sessions too frequently. When a new layer of ink is implanted before the previous one has faded sufficiently, the ink begins to accumulate within the skin, creating multiple overlapping layers over time. This often results in eyebrows that appear darker, blurrier, and less natural as the years go by.

This is why I emphasize that there is no such thing as an “annual touch-up.” Permanent makeup should only be refreshed once the existing pigment has faded by at least 80%. With natural-looking techniques, this process may take one to two years, or even longer, depending on your skin, lifestyle, and individual healing process.

More saturated techniques may appear to last longer because they retain more pigment in the skin. However, they don’t necessarily fade grace fully. Instead of gradually becoming lighter over time, they often remain dense and saturated, making future corrections and color adjustments much more challenging.

The Layer of the Skin Matters

The skin is made up of three main layers: the epidermis, the dermis, and the hypodermis.

One of the biggest differences between a traditional tattoo and permanent makeup isn’t just the type of ink we use, it’s also the layer of the skin where the ink is implanted.

The epidermis is the outermost layer of the skin and has the highest regenerative capacity. In other words, it constantly renews itself as part of the body’s natural defense and healing process. As old, damaged, or dead skin cells are shed, they are replaced by new cells produced in the deeper layers of the skin.

During a permanent makeup procedure, a small amount of pigment is deposited within the epidermis. Because this layer is continuously renewing itself, that portion of the pigment naturally fades over the following weeks and months as the skin goes through its normal cell turnover cycle.

Protect your eyebrows with sunscreen every day, and don’t forget to keep your skin well hydrated.

Excessive sun exposure is one of the main factors that accelerates pigment fading, while healthy, well-moisturized skin provides a better environment for long-lasting results. By protecting your skin from UV damage and maintaining a consistent skincare routine, you can help preserve your permanent makeup and keep the color looking fresh for longer.

The remaining pigment is implanted into the upper dermis, which is where long-lasting results are achieved. Unlike the epidermis, the dermis does not continuously shed its cells, so pigment placed in this layer remains visible for much longer.

Over time, however, the body gradually removes these pigment particles through a natural immune process called phagocytosis. During phagocytosis, specialized immune cells slowly engulf and break down foreign particles, including permanent makeup pigment. This process occurs gradually over months, or even years, which is why permanent makeup fades slowly rather than disappearing all at once.

Although pigment is considered a foreign substance, it is generally biologically inert. Because it doesn’t pose an immediate threat to the body, the immune system removes it slowly and progressively, allowing the color to soften over time rather than being eliminated immediately.

Traditional tattoos are also implanted into the dermis, but at a deeper level than permanent makeup. This difference in implantation depth is one of the main reasons traditional tattoos are designed to be permanent, while permanent makeup is intended to fade gradually overtime.

Another important difference is the pigment formulation. Traditional tattoo inks contain a much higher concentration of pigment relative to their liquid carrier, making them denser and more saturated. Permanent makeup pigments, on the other hand, are formulated with a higher proportion of liquid, resulting in a lighter, less concentrated consistency.

This lower pigment density allows for softer, more natural-looking results and contributes to the gradual fading that is characteristic of modern permanent makeup techniques.

TYNDALL EFFECT

The Tyndall effect is an optical phenomenon that occurs when light passes through the skin and interacts with pigment particles beneath its surface. As light encounters these particles, shorter wavelengths, particularly blue light, are scattered more efficiently than longer wavelengths.

As a result, the pigment can appear cooler, grayish, or even slightly bluish to the human eye, even when its original color was warm brown.

In permanent makeup, the Tyndall effect helps explain why some healed eyebrows develop a cool-toned appearance over time. Rather than being caused solely by the pigment itself, the final color we perceive is also influenced by the way light travels through the skin before it reaches our eyes.

This is why the healed color of permanent makeup is determined not only by the pigment formula, but also by the optical interaction between the skin, light, and the implanted pigment.

When pigment is placed too deeply and saturated in the dermis (reticular layer), light passing through the skin must travel through more tissue. Along this path, light waves are increasingly scattered by dermal collagen fibres and water.

For this reason, there is a safe limit to how dark permanent eyebrows should be. The goal isto control the amount of pigment implanted into the skin, allowing the body’s natural immune system to gradually break it down and remove it over time.

When too much pigment is deposited, the skin becomes oversaturated. As the permanent makeup ages, the different pigment components do not fade at exactly the same rate. The warmer tones that originally created a natural brown appearance tend to diminish first, while the black pigment typically present in a higher concentration and composed of smaller particles remains more visible.

As a result, what once appeared to be a soft brown eyebrow can gradually develop a cooler, grayish tone. This color shift is often not caused by the pigment itself, but by excessive saturation and the way the pigment ages within the skin.

It’s also important to remember that pigment aging is influenced by more than just technique.

Lifestyle, overall health, and environmental factors can all affect how permanent makeup heals and fades over time. Smoking, prolonged sun exposure, certain prescription or long-term medications, and nutritional deficiencies—such as low iron levels—may all contribute to changes in pigment retention and color as the eyebrows age.

Even when a procedure is performed correctly, with the appropriate implantation depth, proper pigment saturation, and a suitable technique, the healed color may still develop as light cool or grayish shift over time due to these external factors. This is a normal part ofthe aging process of permanent makeup and is typically subtle and that's why we should always work softer and lighter, especially in the first session in order to understand how each skin / client reacts with the treatment.

In most cases, this mild color change does not compromise the overall appearance of the eyebrows. Instead, the brows simply become softer and lighter while maintaining a natural, harmonious result.

While no artist can control every factor that influences pigment aging, choosing the right technique, implanting pigment at the correct depth, and avoiding oversaturation are essential to ensuring that permanent makeup heals beautifully and continues to look natural for years to come.
