The Wild Rosella is known for its ability to tolerate extreme environments, which reflects on how it works with our skin. The calyx that surrounds the flower (typically a green outer layer that encloses the flower) works to protect it from drought and other environmental stressors during its development, aka transferring hydration to the flower. Well, our Wild Rosella Sunscreen SPF 50+ works in the same way as the calyx, providing protection and hydration to your skin.
