Collagen like all proteins is made up of amino acids. These amino acids, nine are considered essential that mean they cannot be synthesized by the body and must be acquired through the diet.
The growth of collagen, elastin, and melanin can all be stimulated through laser therapy, involving intense wavelengths of light. This method can be used in the treatment of stretch marks.
Other nutrients that may support collagen formation include:

1. Proline: found in egg whites, meat, cheese, soy and cabbage20

2. Vitamin A: found in animal-derived foods and in plant foods as beta-carotene.

3. Vitamin C: found in oranges, strawberries, peppers and broccoli

4. Anthocyanidins: found in blackberries, blueberries, cherries and raspberries

5. Copper: can be found in shellfish, nuts, red meat and some drinking water
