'Clearly, Bono and his wife, Ali Hewson, were on to something when they decided to back Nude, a British eco-friendly skincare range. One of the ingredients featured in the line is the acerola berry, which is native to several Caribbean islands and generating excitement among beauty buffs for its complexion brightening properties.
