Useful if: choose it if you want a richer night cream with 5% niacinamide rather than another lightweight serum step.
The main difference is format. This is a final moisturiser step rather than a thin active serum, so it makes more sense for someone who wants niacinamide inside a richer night product.
The formula includes emollient ingredients such as shea butter and squalane alongside the niacinamide, making it a different routine role from a simple water based serum.
The current ingredient list places niacinamide near the top and also includes tranexamic acid, glutathione, panthenol, Centella related ingredients, ceramide NP and several hyaluronic acid forms.
That is a broad formula, so the most useful buying question is whether you want these ingredients combined in one night moisturiser rather than layering several separate leave on products.
Use it as the final moisturiser step in the evening after lighter serums or treatments. There is usually no need to apply a second moisturiser over it unless the skin still feels dry.
If you already use a strong niacinamide serum, consider whether duplicating niacinamide across multiple leave on steps adds anything useful to your routine.
