Vitamin C Face Serum 15% L. Ascorbic Acid, Ferulic Acid .5% + Vitamin E for Self Care and Beauty, Face Dark Spot Corrector and Anti Aging 1oz, Made In The USA

This 15% L-ascorbic acid serum delivers solid vitamin C performance at an accessible price point. The formula's inclusion of 0.5% ferulic acid and vitamin E creates a stabilizing trio that theoretically extends the serum's efficacy and shelf life—important given vitamin C's notorious instability. Upon application, it absorbs quickly without the sticky residue common to budget options. The concentration is potent enough to address hyperpigmentation and fine lines noticeably within 4-6 weeks of consistent use. However, the texture skews slightly watery, and I detected no noticeable scent stabilizers, suggesting oxidation risk if storage isn't careful. Made-in-USA manufacturing adds credibility, but the 1oz size depletes faster than competitors offering 1.5oz.
