8 experts · Strong agreementWhat the gurus are saying
This serum earns consistent praise for delivering potent brightening and antioxidant benefits at around $23, often compared favorably to serums that cost nearly ten times as much. The 15% ascorbic acid concentration at a pH of 3.2 allows good penetration, and most find it layers smoothly without heaviness or irritation, though those with very sensitive or dry skin may want to patch-test first since the acidic pH can feel spicy for some. One caveat that matters: the formula can oxidize and turn brown if stored improperly, so buy from the brand's website rather than retail stock that may have sat around.
