Supplements with too much Vitamin A can be toxic to the liver since Vitamin A is a fat soluble vitamin (meaning more gets stored than excreted.) Sweet potatoes and other foods rich in Vitamin A, however, do not cause liver toxicity and can not be stored for long-term use like supplements can.
The wound healing stages are made up of three basic phases: inflammation, proliferation and maturation. There are many types of wounds that require different wound care products for proper recovery from an ulcer or laceration, but most go through similar healing stages.
When the top layer â the epidermis â is broken by a light scratch, not much occurs. You might see some dead skin cells flake off. But when something cuts into the deeper, next layer â called the dermis â youâll see blood, and your body triggers a four-stage process of healing itself. The skin has to respond to two major threats at first: the loss of blood, and the lack of a physical barrier (the epidermis) between your innards and the outer world.
