The "optical magician" of cosmetics

 

Why do top-tier lipsticks create a luxurious satin sheen with a single swipe? Why do top-tier foundations have a built-in "soft-focus" effect? ​​Putting aside the marketing gimmicks, the true driving force behind these effects is often found at the back of the ingredient list: trimethyl pentaphenyl trisiloxane, a luxurious ingredient that's a bit tricky to pronounce but actually smells amazing.
