look if you really think u are and u wan to change. thats fine i cant tell you that you are if you dont believe it. If you are allowed and u want to use makeup, you should try, since you are only 14, i recommend not to use that much, if acne is a huge problem for you, treat your face with some acne products that could help you ...if u are not in the time of easting money its fine, look up for natural mask face and natural treatments. some mascara, lipstick that may not be too colorful, you can try some small foundation just to cover some imperfections, if u feel maybe you look ugly because you are out of shape, eat healthier or try to do some exercise, change your hairstyle, do different things , straigh it, or try some braids. if u wear glasses look up for some tips, look for glasses that match you face shape. if your skin in in the dark tones wear bright color like white, orange yellow, if not then the opposite, but do something different, you can use perfume it helps alot. wear some earrings if u can , they usually brighten the face.I WISH U BEST OF LUCk! Feel comfortable with the way you are and if right mpw you dont, then work for it, its nothing to be ashamed about!
