The Optical Physics of Epidermal Clouding Over Dermal Ink
Tattoo pigment particles are permanently encapsulated within dermal macrophages and fibroblasts located in the dermis (the second layer of skin). When you look at a tattoo, you are viewing the ink through the overlying epidermis and stratum corneum.
When the epidermis becomes dry, dead keratinocytes accumulate in rough, irregular layers. This causes diffuse light scattering, making black ink look ashy and chalky, and colors look muted. Applying rich botanical lipids fills micro-cracks in the stratum corneum, restoring optical transparency so the vibrant ink shines through clearly.
The Photodegradation of Dermal Tattoo Pigment
Ultraviolet radiation (UVA and UVB) is the primary enemy of tattoo longevity. High-energy UV photons penetrate into the dermis, cleaving the chemical bonds of heavy metal and synthetic pigment particles.
Once broken down into micro-fragments, the body's lymphatic system carries the pigment particles away, resulting in faded, blurry lines. Applying broad-spectrum SPF 50 daily over exposed tattoos is the single most effective way to prevent permanent ink degradation.
