"It’s a good serum"

It’s very lightweight, just started using it so might take time to see results but the only drawback is the packaging, the pump makes it hard to squeeze out the serum idk why. It’s a good serum overall for small acne bumps/ to even out skin tone

    "Good"

    I've recently started using this product. It's lightweight watery texture formula that absorbs immediately into the skin and has no scent. So far I'm liking this product.👍🏻

    Using it AM and PM. Gives good results if pigmentation is your concern. Feels little sticky, but can tolerate it for the results it shows. Love it.

    "Good product"

    It's my first time trying niacinamide product so can't say much. But nonetheless good product. Water like consistency. Feels little sticky on skin. But no harm in trying.
