TATCHA Serum Stick is an intensive moisturizing balm intended for targeted hydration. And with this Auto-Delivery plan, you'll receive a new stick every 90 days for two years. The formulation includes squalane, along with Japanese lemon balm extract and Hadasei 3 to help provide moisture in dry areas of the face. The stick delivery makes it easy to apply to specific areas of the face that looks dry. The Serum Stick helps improve the look of dry fine lines, and help to relieve that uncomfortable tightness that comes with dry skin. Due to its formulation, the Serum Stick can also double as a touch-up balm and be used over makeup to keep it looking fresh all day. How do I use it: Glide onto any dry areas to target treat -- under eyes, cheeks, outer corners of the eyes, forehead, and more. From TATCHA.
