Having foods rich in amino acids and Vitamin C can increase the levels of both collagen and hyaluronic acid in the body. These two are crucial components to reduce skin aging. Foods like red peppers, kale, eggs, fish, dairy products, oranges, Brussels sprouts, strawberries, and broccoli are all rich in Vitamin C.
In addition to this, factors such as good sleep, weight lifting, and steam bath are some natural methods to boost collagen. Nevertheless, they are not as effective as collagen stimulating treatments.
