you do not need to spend a bunch of money to become the girl of your (and everyone else's) dreams. what you need is to take a good look at your daily habits and understand that beautiful hair and skin come from clean eating habits and hydration; that a gorgeous body comes from adequate nutrition and physical effort; that confidence comes from a tranquil mind and decent sleep; that no person of importance neglects their hygiene or dwells in excessive behavior... it needs to start from a force within you, from intuitive adjustments. then, afterwards, you can buy the expensive moisturizer. as a treat, not a need.
