Urea: A humectant and keratolytic agent used in skincare to moisturize and soften the skin. Urea is often included in products for dry or rough skin, as it helps to exfoliate dead skin cells and improve the skin’s ability to retain moisture.

UVA/UVB Protection: A term used to refer to the protection offered by sunscreens against the two types of ultraviolet (UV) rays. UVA rays penetrate deeply into the skin and contribute to aging, while UVB rays cause sunburn and can lead to skin cancer.
