For an ethical beauty treat, Nude skincare is top of our list of must-have pick-me-ups, and the latest innovation from the natural, ethical and sustainable skincare brand is the gorgeous Advanced Cellular Renewal Serum which launches on 15th September. The serum promises to improve skin texture and radiance from the very first use and it’s already loved by Kim Cattrall, Uma Thurman, Helena Christensen and Erin O'Connor. To celebrate the launch, Nude have kindly offered 400 lucky Grazia Daily readers the chance to win a 3ml sample of the serum, presented in a cute mini glass bottle. All you need to do is email firstname.lastname@example.org and put Grazia ACRS in the subject header. Easy! If you’re not lucky enough to bag a sample, you can pre-order the serum by heading to www.nudeskincare.com.
