The one thing I always have in my handbag is SPF lip balm. I recently discovered CeraVe's Healing Repair lip balm with SPF. I always apply lip balm with SPF to protect my lips against UVA/B rays. It's so easy to remember your facial and body sunscreen, but a lot of people forget to apply SPF to their lips, too. I really recommend trying their SPF lip balm.
