Treatment of scars
Damage to the epidermis does not leave scars. Injuries that penetrate through to the dermis do however. The deeper the skin injury, the longer it takes for the skin barrier to be restored. The renewal of the epidermis takes just fourteen days, but depending on the depth of the wound the increased trans-epidermal water loss (TEWL) may persist for 150 to 500 days. While the epidermis is not functioning completely and the dermal remodelling is not completed, the barrier function of the renewed skin is problematic and needs special care in order to combat further water loss. This renewal process goes hand in hand with a dry, itchy skin that is much more sensitive and which is more easily penetrated by irritant substances, allergens and micro-organisms.
Essential fatty acids
Linoleic and linolenic acids are essential fatty acids that are not produced by the body naturally. They have to be ingested in the form of food. These fatty acids are necessary for the synthesis of cell membranes and prostaglandins, for defence and growth mechanisms and for the physiological and biochemical procedures of cell regeneration. A lack of these fatty acids leads to red flaky skin with increased porosity. Several surveys have confirmed the positive effects of locally applied essential fatty acids. Local application of linoleic and linolenic acid slows down the trans-epidermal water loss and the emergence of elements that increase the risk of inflammation.
The local application of Rosa Mosqueta (rose hip) oil that contains 80% linoleic and linolenic acid, strengthens the skin barrier and reduces the risk of irritation. Rose hip oil is used in Naqi Repair, Naqi Massage Oil Repair and Naqi Cica Creme.

Burns
Even after a burn on the surface of the skin has healed, the regeneration of the skin is a long way from being complete. The fragile, new skin is very sensitive and needs extra nourishment and care. The barrier function is not yet optimal, so that a lot of moisture is lost and the skin remains sensitive. Zones that have been burned can still itch from time to time. The regeneration of the skin, depending on the depth of the burn, may take several weeks or even years. Appropriate skin care is recommended therefore. |
