Hey there, I'm a 19-year-old blogger, freelancer and affiliate marketer who loves to spread awareness and education. I'm a blogger who believes you should let your natural beauty shine. The changes we make to our look should enhance us, not define us. Feel good about finding your favourite new expression of self! Looking good should also be healthy for us and our environment. I promote the work of cruelty-free companies that do not participate in unethical testing or labour practices. We look our best when we let our real selves shine through, not when we cover up what makes us unique. Let me guide you down new paths that will enhance your natural glow.
