Overview/Definition
Ornithine is a non-essential amino acid that plays a crucial role in the body's urea cycle, where it helps in the elimination of ammonia, a byproduct of protein metabolism. It is naturally produced in the body and can also be synthesized in a laboratory. Ornithine is not used to build proteins but is involved in various physiological processes, including wound healing, collagen production, and supporting the immune system. In skincare, ornithine is valued for its ability to promote skin regeneration, improve elasticity, and enhance the skin's barrier function. It is often found in anti-aging products due to its potential to reduce the appearance of fine lines and wrinkles and improve overall skin texture. Ornithine's benefits in skincare are attributed to its role in increasing the production of collagen and other structural proteins in the skin, which helps maintain skin firmness and hydration. It is suitable for all skin types and is particularly beneficial for those concerned with aging skin or seeking to improve skin resilience and tone.
