What's This Little Ray?

The aliens' 'Super UV Destroyer Mothership' descended upon Earth, declaring they would burn and tan all life on the planet with cosmic-level UV rays within ten minutes, destroying everyone's collagen. Global scientists were helpless, and humanity fell into collective appearance anxiety and doomsday panic. At this moment, Bella Chi stepped forward. She stood on a rooftop, facing the most intense and aging-promoting UV rays in the universe. The aliens provocatively asked, "Aren't you afraid of this radiation that can destroy everything?" Bella Chi, touching up her makeup in a mirror, sneered, "Do you know who I am? I'm the ultimate spokesperson for 'Sensitive Combination Skin'! Fighting sensitivity and picking sunscreens every day, what's this little ray to me?" With that, she took out an 'Ultimate Anti-Sensitivity Physical Sunscreen Primer' developed by an online startup, mixed it with setting spray, and unleashed a flawless 'Beauty Barrier Burst' towards the sky. The sunscreen transformed into a giant golden shield in the air, not only reflecting 100% of the cosmic UV rays from the alien mothership but also using the principle of mirror reflection to shoot the light back at the mothership, turning the aliens' spacecraft into one scorched, tacky-looking mess after another. The alien commander, seeing their mottled ships, shamefully fled Earth with their mothership.
