Certain factors slow down healing:
Damage to the skin, or “lesions” can be either epidermal (affecting the most superficial layer of skin and non-bleeding) or dermal (affecting the deeper layer of skin and bleeding). Whenever the dermis is affected, all wounds, burns, surgical incisions, or infections leave behind some kind of scar. That is not to say that all scars are equal: The goal of any treatment is to improve the healing process for the best-looking scar possible,which should be flat, supple and close to your skin tone.
- Age: The skin heals faster in young people.
- Diet: An unbalanced diet lacking in vitamins and trace elements can lead to slower healing.
- Diabetes: Wounds may heal very slowly in poorly controlled diabetes.
- Smoking: Results in decreased oxygenation of the wound and slower healing.
- Certain medicines: Immunosuppressants and corticosteroids can delay healing.
