Early verdict · Few reviews so farWhat the gurus are saying
The fragrance in this serum is the main concern because it pairs poorly with the exfoliating acids in the formula, risking skin irritation and barrier damage with daily use, especially for sensitive skin. Experts split on whether the brightening effect comes from the most potent form of vitamin C or primarily from the exfoliation itself. The formula spreads easily and includes vitamin E for stabilization, but the fragrance risk may outweigh the benefit.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.
Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
