Optimize visible recovery
Sero XO
Advanced Plant Exosome + Antioxidant Recovery Serum
Sero XO is an advanced daily serum formulated for skin that looks stressed, dull, sensitized, or visibly depleted. Powered by a concentrated Plant XO Complex, two lipid-soluble forms of Vitamin C, and a barrier-supportive blend of phospholipids, squalane, antioxidants, and amino acids, it helps restore a calmer, brighter, more resilient-looking baseline.
The formula takes a multi-pathway approach to skin optimization. Plant XO Complex helps condition visibly stressed skin and support a smoother, healthier-looking appearance, while THD Ascorbate and Ascorbyl Palmitate help improve the look of uneven tone and loss of radiance. Ferulic Acid and Vitamin E strengthen the formula's antioxidant network to help defend against the visible effects of environmental stress.
Phosphatidylcholine, phospholipids, squalane, glycerin, and amino acids complete the system with lightweight moisture and barrier support. The result is skin that feels replenished and looks clearer, more luminous, and better balanced—without a heavy finish.

Why it is different
More than an exosome serum. A complete system for visible skin recovery.
Sero XO places Plant XO Complex at the center of a broader recovery-focused formula. Rather than relying on a single hero ingredient, it combines plant-derived skin-conditioning technology with stable Vitamin C, Ferulic Acid, Vitamin E, amino acids, humectants, and barrier-supportive lipids.
This integrated approach addresses several visible signals of skin stress at once—including dullness, uneven-looking tone, dryness, sensitivity, and loss of resilience. It is advanced enough to support a professional skincare plan, yet lightweight and streamlined enough for consistent daily use.
