Most people over do the fillers. Less is always more! I had 0.5 in my cheeks recently, to lift the lower part of my face. People don't have it done to specifically change their cheeks, but usually to lift the drooping on the lower part. It also lessens the appearance of hollows under the eyes. It's less pleasant than botox, as there is a feeling of pressure and a sort of crackling noise, which only you can hear. You also get swelling and soreness for up to a week, so might explain why Demi Moore looked so odd recently, didn't allow enough time to recover before going on the runway. Botox can make a person look frozen, but it doesn't bother me as I am a serial frowner, so I will happily never frown again!
