4. “No room” problem
Scar tissue formation is critical to the skin's healing process, particularly noticeable in procedures like Powder Brows creation or microblading. When the skin is injured during such procedures, it initiates a healing response, one aspect of which is scar tissue formation. This scar tissue primarily comprises collagen, produced by cells known as fibroblasts. Collagen is a structural protein that lends strength and structure to the scar, playing a vital role in the repair process.
On a microscopic level, the physical interaction between pigment particles and the surrounding tissue matrix is complex. In normal skin, there's a balance between the size of pigment particles, their distribution, and the surrounding tissue architecture. In scar tissue, this balance is disrupted, potentially leading to uneven pigment distribution and lesser overall deposition. In scar tissue, there is a higher chance of pigment particles being more densely packed or encapsulated in certain areas, potentially leading to uneven pigmentation.
Implanting pigment
In the specific context of creating Powder Brows, pigments are introduced into the skin's dermal layer. Here, fibroblasts play a crucial role. They encapsulate these pigment particles, a process integral to healing. Fibroblasts effectively "wrap around" or incorporate the pigment particles into the developing scar tissue during encapsulation. This encapsulation is essential for the stability and longevity of the pigment in the skin.
However, the process can become complicated when there is excessive scar tissue formation. Normally, fibroblasts produce an optimal amount of collagen to form healthy scar tissue, effectively encapsulating the pigment particles. But, factors like excessive trauma from the procedure, infection, or an overactive healing response can lead to an overproduction of collagen. This results in excessive scar tissue characterized by its dense and thick nature.
The effects of too much scarring
Such density in the scar tissue can pose significant challenges. It may impede the fibroblasts' ability to encapsulate the pigment particles properly. In a dense collagen network, there is limited space and reduced flexibility, making it difficult for fibroblasts to interact with and effectively encapsulate the pigment. Consequently, this can lead to uneven distribution of the pigment or instability in its placement, ultimately affecting the quality and appearance of the semi-permanent makeup or tattoo. Thus, there are fewer normal skin cells and structures in scarred or fibrotic tissue. The dense collagen matrix of scar tissue may provide fewer sites for pigment particles to adhere to or be encapsulated by the surrounding cells and tissues.
In simple terms, think of fibroblasts as workers trying to organize and store items (pigment particles) in a warehouse (the scar tissue). If the warehouse is properly sized, they can store the items neatly. But suppose the warehouse is overly packed and cluttered (like in excessive scar tissue). In that case, the workers find it hard to store the items properly, leading to a disorganized and less effective storage system.
