Early verdict · Few reviews so farWhat the gurus are saying
This serum splits the experts. One dermatologist approves it outright, while another praises its niacinamide and alpha arbutin for evening skin tone and creating glow, but warns that the kakadu plum form of vitamin C breaks down too quickly to work effectively on skin. That instability means the brightening you see likely comes from the other actives, not the vitamin C, so those with dark spots may want to look for a product with a more stable vitamin C form if that ingredient matters to them.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.
Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
