The Theory Retinol Creme Blend Introducing our most luxurious formula yet — an all day moisturizer formulated with retinol, hyaluronic acid and vegan oat milk. The Theory™ is young. It’s new. It’s an iced London fog latte, California vegan style. It’s organic oat milk. It’s a skin latte of love. It’s the retinol, for me. What’s your theory of youth? Ours is that it’s free. It’s the way we love, laugh, cry. It’s the first snow. Your first love. Your first wrinkle — don’t be shy, let her live. But let’s maybe ask her to calm it down. Youth is free. You can’t take mine, go get your own. It’s inside you. Steal it. Youth is a mindset. Feel what’s real. That’s the theory.
