Holiday Duo Gift Set: A special 2-piece retinal set created just for shoppers, inspired by customers who keep this formula in their routine and their feedback. Perfect for holiday gifting and stocking stuffers. High-Strength 0.1% Retinal Care: Powered by 0.1% retinal - a more advanced form of retinol - and A-Shot technology, this formula helps deliver actives deep into pores for smoother, firmer-looking skin and more refined pores. A refined micro-particle ingredient, 16 times thinner than pores, is designed to penetrate directly into pores and enhance the absorption of active ingredients. Through high-purity separation and refinement, the particles are uniformly sized, reducing skin irritation. Liposomized Retinal & Matrixyl: A liposomized retinal and Matrixyl formula that targets the look of wrinkles, uneven texture, and enlarged pores, giving troubled areas a more elastic, refined appearance with just a few drops. Micro-Particle Delivery System: Ultra-fine particles, about 16x thinner than pores, are designed to fit into pores and support better absorption while maintaining a uniform size to help minimize irritation. Beginner-Friendly Usage: New to retinol or retinal? Start every other night for the first 2 weeks, using a small amount on targeted areas. A slight yellow tint on the skin after application is normal and rinses off completely during cleansing. It's a perfect set to gift to anyone trying retinal for the first time.
