As I reach my 40th year, it's become blatantly obvious that I can no longer get away with nothing on my skin! Am going to treat myself to a 'wonder cream/serum' and would like some recommendations. I'm mixed race so I need one for all ethnicities. I need it to brighten my skin, and eve out skin tone. But it's got to be light and non greasy. Help a woman in need before I splash out £40 on something that doesnt work!
