Many royal women prefer foundations that provide hydration and a radiant glow, especially when they are attending events that highlight their skin’s natural beauty. These foundations often contain hydrating agents like hyaluronic acid, as well as light-reflecting particles that help the skin look luminous, without appearing overly shiny or oily. These types of foundations give royal women a naturally glowing, youthful appearance and are especially popular in warmer climates or during the summer months when skin needs a bit of extra moisture.
