In plain English

Benzoxiquine is a man-made chemical added to some skincare products to stop bacteria and fungi from growing. It works like a preservative, helping the product stay fresh longer. However, it is not very common in modern cosmetics, and there isn't a lot of research on how safe it is for everyday use on skin. Because of this, it's usually found in very tiny amounts, and people with sensitive skin might want to avoid it.
