Pro C Serum Brightening Solution with 15% Vitamin C + Ferulic Acid

Serum · 30 ingredients

A brightening serum formulated with a 15% multi-vector vitamin C complex—combining liposomal 3-O-Ethyl Ascorbic Acid, gold-stabilized L-Ascorbic Acid, and THD Ascorbate—to visibly even skin tone while maintaining stability. Tranexamic acid, ferulic acid, and alpha-arbutin work together to defend against visible signs of environmental damage and the appearance of premature aging, while patented peptides and FGF-2 growth factor target the look of dark spots and hyperpigmentation. The formula is suited for those concerned with uneven tone, dullness, and discoloration, and is designed to deliver results without irritation.
