Titanium dioxide (TiO2) is an ingredient used in thousands of food products and cosmetics worldwide to provide a white pigment or UV protection. However, significant safety concerns, especially regarding its nanoparticle form and potential inhalation risks, have led to diverse regulatory actions, prompting consumers to ask, "Should I be worried about titanium dioxide?".

Over one billion people worldwide are estimated to be vitamin D deficient, but the idea that sunscreen is to blame is a common misconception. This article clarifies the scientific truth behind the question: can sunscreen block vitamin D synthesis, and explains how to balance sun protection with your body's vitamin D needs.

According to the Cleveland Clinic, your body's natural collagen production begins to decline in your 20s, which is why supporting it is crucial for skin health. This article explores the best things to do for collagen production, providing a comprehensive guide to nourish your skin from the inside out.

According to the National Institutes of Health, solar ultraviolet-B radiation (UVB) is the primary source of vitamin D for most people. This means that the answer to, 'Do you get vitamin D from UV radiation?' is a definitive yes, though the process is more complex than simply soaking up the sun's warmth.

According to the National Institutes of Health, vitamin D deficiency is a widespread issue affecting a significant portion of the global population. A primary natural source is sunlight, which raises the crucial question: which rays do we get vitamin D from?
