I am still 17 going on 18 and I have yet any idea how to apply makeup and do face treatment and care. I have used acne face treatment from Clinique but nothing else yet. I have so many lipsticks, lipglosses, eyeshadows and Chanel eyepalettes and lipstick palettes, but I don't know how to put foundation on. Can anyone recommend how to put foundation and concealer as well as daily cleansing treatments on? And also, can you recommend any US-sold makeup?
