Model Arlenis Sosa has a message, and it's en español: if you've been wanting to try Lancôme's Génifique Youth Activating Concentrate ($78–$125), do it this Friday. The French brand has dubbed Oct. 22 Genes Day, to celebrate "the beauty of scientific research." For each bottle of Génifique sold on that day, $7 will be donated (with a minimum of $100,000) to St. Jude Children’s Research Hospital. (We liked how Génifique made our skin brighter and smoother, for what it's worth.) All purchases at Lancôme counters and online will raise funds for pediatric cancer research, but you can also receive a free seven-day sample if you'd like to try it out first. Win-win.
