Most scars that form after small and shallow injuries disappear without a trace over time. But there are also those that require treatment. What does it depend on and how to proceed so that the scar becomes the least visible? How to get rid of razor bumps?
Scars – how to care for a wounds
This is determined by the type of scar formed at the site of injury.
Normal scars are initially thick, hard, blue-red, itchy. Over time, they soften, become brighter, and the itching disappears.
What to do: If the scar is small and not visible, you can leave it alone. The larger or visible wounds after complete sealing should be lubricated with ointment or gel (e.g. Alcepalan, Cepan, Dermaliz) and gently massaged in a circular motion.
Hypertrophic scars are formed when the natural wound healing process is disturbed. They can extend beyond the wounded area and are often inflexible.
What to do: Protect the skin from stretching or stretching. So that the scar does not grow, it is worth lubricating it with onion ointment or applying a special silicone patch on the scars.
Atrophic scars are formed after chickenpox and juvenile acne. They resemble tiny dimples. They arise when, during wound healing, the body does not produce enough connective tissue fibers.
What to do: The pimples cannot be squeezed and the scabs must not be removed. To eliminate itching, the pustules can be lubricated with zinc ointment. If scars remain after acne, it is worth doing microdermabrasion.
Keloids (keloids) form after the wound is healed. They have the shape of bulges and tend to be larger than the area of damaged skin. They are hard, often very pink and painful when touched. They arise in people whose body is prone to excessive collagen production.
How is scar healing done?
Scar formation is a natural process of healing the body. Damaged skin is replaced by connective tissue. Wound healing takes place in four stages.
The inflammatory phase begins at the time of injury. Within 24-48 hours, tissue hyperemia occurs and capillary permeability increases. The wound is filled with a blood clot, which is a biological dressing – protects the wound from dehydration and pathogenic microorganisms. Fibrin accumulates on the edges of the wound, which is a scaffold for the scab formed on the wound.
The limited inflammatory phase is the stage at which the wound cleans itself. Feeding cells (macrophages) flow into it, which remove the dead ones. Blood vessels penetrate the wound, for which the body needs about 7 days.
The healing phase is the time during which fibroblasts, i.e. connective tissue cells, intensively produce collagen supporting the scar. Cells of connective tissue multiply and an epithelium forms above them. There is a balance between the amount of collagen produced by the body and the amount that is broken down and removed. It is good to know that the correct healing and disinfection of the wound affects the correct healing process. And the correct healing process reduces the risk of visible scars.
The scar remodeling phase usually lasts from several months to even over a year.
