Frequent exposure to UV rays from the sun, without adequate protection, can also degrade hyaluronan. Additionally, our environments can play a part; pollutants and toxins, such as smoke or certain chemicals, can negatively affect our hyaluronic acid levels. Ensuring a healthy lifestyle, protecting your skin from the sun, reducing exposure to pollutants, and having a nutritious diet and vitamins supplementation are all important in maintaining our hyaluronic acid levels.
