What the gurus are saying
The 30% ethylated ascorbic acid concentration delivers impressive results on hyperpigmentation and glow, but reviewers sharply split on the trade-off: some find the irritation unbearable, while others argue results justify it, especially for resilient skin. The stabilized formula stays effective for six to nine months without oxidizing, and the lightweight texture spreads easily into skin.

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.
