UVB rays can cause redness, sunburn, hyperpigmentation, and skin cancer, among other things.

In the long term, UVA rays lead to oxidative stress in the cells, which is responsible for DNA damage and lightrelated skin aging, so-called photoaging. This can lead to wrinkles, sagging of the skin, and loss of volume.

Blue light, including that from screens & displays, can contribute to premature skin aging, such as the development of fine lines and wrinkles.
