For all normal skin, the basal metabolic cycle time is 28 days, so according to this repair cycle time, it is better for people who have tattoos to come back for a month after repair. One is conducive to people to observe the deposition of dye in the subcutaneous tissue as soon as possible after skin repair. 2. Whether the color changes after the skin's basic metabolism in a cycle.
Let's take a look at the epidermal cells first. The epidermal cells have no nucleus, and gather together to form a thin sheet with a thickness of 0.02~0.03cm. Responsible for protecting the skin's physiological function against external aggression.
The thickness, thickness, and elasticity of the skin vary from person to person. Generally speaking, thicker skin is thicker, tighter, and relatively less elastic. Thinner skin will be more delicate and relaxed, with greater elasticity. The skin on the torso and extremities is thicker than the flexor, the palm and plantar skin is thick, and the skin on the eyelids, ears, and breasts is thin.
Where the skin is thick, it is usually under heavy load, and it is easy to contact and rub with the outside world. Therefore, the thicker skin can fulfill the protection responsibility. Through the thin distribution of the skin, we can better analyze the coloring of the needle under the customer's skin and let the work Let's take a closer look at the skin, cut the skin into very thin pieces, stain it and put it under the microscope for observation, from the outside to the inside, the slice is divided into three layers from top to bottom, epidermis, dermis and subcutaneous tissue For our tattoos, we only need to analyze the epidermis and dermis, and the subcutaneous tissues are more complex human tissues such as fatty peripheral nerves and blood vessels.
From the perspective of everyone's skin, our epidermal layer is the first to come into sight, and only the epidermal layer has 5 points. They are mainly composed of keratinocytes and dendritic cells. The major feature of keratinocytes is that they start from the basal layer inside the epidermis and continue to grow and multiply. After the spine cell layer, the granular layer, and the transparent layer (not all parts), they are completely keratinized to form the outer stratum corneum. Cuticle cells shed continuously.
The epidermal growth cycle refers to the entire process in which the basal cells of the epidermis grow outwards to complete the keratinization transformation, and the exfoliation of the old generation of keratinocytes. It usually takes 3 to 4 weeks. In addition to keratinocytes, there are melanocytes containing melanin in the basal layer of the epidermis.
