FORMULATED WITH ADVANCED RETINAL & LIPOSOME DELIVERY SYSTEM: Our formula applies a liposome delivery system to Retinal, the next-generation form of Retinol that works up to 11 times faster. This technology enhances ingredient stability and boosts absorption for more visible results.
INFUSED WITH RETINAL LIPOSOME 2%: helps reduce the look of fine lines, uneven skin tone, and rough texture for smoother, more radiant skin.
RETINAL BOOSTING COMPLEX: Powered by Black Ginseng Extract, Bakuchiol, 3 Peptides, and Niacinamide, this antioxidant-rich formula refines pores, smooths skin texture, and promotes a more balanced complexion.
RETINAL USAGE TIP: 1. Nighttime use is recommended, as Retinal may oxidize when exposed to sunlight. If used during the daytime, make sure to follow with sunscreen. 2. To build Retinal tolerance, start by using it twice a week during the first 1–2 weeks, then gradually increase frequency as your skin adjusts.
HOW TO USE: 1. After cleansing and toning, apply an appropriate amount evenly over the face and neck. 2. Gently massage until fully absorbed, then follow with a moisturizer.
