Food has sugars and other minerals. Excess of Sugar shall increase diabetes. So to control this sugar immediately after a meal insulin is secreted. This is why people who have less insulin inject it right after a meal.
An increase in insulin leads to a decrease in blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, especially muscle and fat cells. It also inhibits the production of glucose in the liver and promotes the storage of excess glucose as glycogen or fat.
GLUT4 is a protein that helps transport glucose into cells. Insulin signals cells to increase the production of GLUT4, allowing more glucose to enter the cell. This process is crucial for regulating blood sugar levels and providing cells with energy.

Insulin assists in metabolizing carbs and the storage of glucose for cell energy. It also helps to use the fat, protein, and minerals from the food that is digested.
Insulin levels can be increased by taking exogenous insulin as a medication injected under the skin and absorbed into the bloodstream. Insulin deficiency usually occurs in Type 1 (juvenile) diabetes that starts at a young age (children, teens, young adults). Type 2 diabetics (onset in adulthood) usually have high insulin levels, but the insulin does not work effectively to get sugar to move from the blood into the cells. These people need to increase the effectiveness of the insulin they produce at the cell level, and there are medications (oral) that can help with this. The overall need for insulin can be reduced by reducing sugars in the diet and reducing one's body weight. Exercise helps insulin be utilized more effectively as well.
Insulin is not produced by skin cells.

Insulin-independent cells are primarily muscle cells and nervous system cells. These cells do not rely on insulin to take up glucose for energy. Instead, they have insulin-independent glucose transporters that allow them to take in glucose from the bloodstream without the need for insulin.
If you stop taking insulin, your body will not be able to transport glucose(sugar) into your cells. Glucose is the chief energy source for all the body's cells. Your blood sugar level will increase, and your cells will essentially begin to starve for lack of an energy source.
Insulin formed by the Golgi apparatus in insulin-producing cells leaves those cells by exocytosis. This process involves the insulin-containing vesicles fusing with the cell membrane and releasing insulin into the bloodstream.

If the body does not have enough insulin, then one can get diabetes. If the cells can not use the insulin the body has very well, then one can get diabetes. If one has diabetes, then the doctor might say to use insulin. If the body has too much insulin, then the cells store energy in the cells as fat. When a person is overweight, that is one of the main symptoms of diabetes. If the body and cells use insulin well to control blood sugar level, then the person is not diabetic.
The beta cells of the pancreas produce insulin and C-peptide, a byproduct of insulin. Source: Wikipedia
Insulin is released from the pancreatic beta cell due to a symphony of signals. 1st is the increase intracellular level of glucose after we eat. As glucose increases this also increases the intracellular ATP. The increase in ATP closes Potassium channels. This depolarizes the cell. The depolarization opens voltage gated calcium channels and the influx of calcium. Then in a complicated process this causes more calcium to enter the cell from the ER. The huge influx of calcium into the cell cause the insulin containing vesicles to move to the membrane for release of the insulin into the blood stream.
