👉 The term "retinian" refers to a group of amino acids that are involved in the formation and maintenance of skin cells. These proteins, also known as keratins, play a crucial role in maintaining the integrity and health of the skin. They help to protect the skin from damage caused by environmental agents such as UV rays and extreme temperatures. Additionally, retinoids, which are a group of active ingredients produced by the body, can also be beneficial for skin health.
