Useful if: choose it if you want a gentler vitamin C style serum with a thicker gel texture and added niacinamide rather than a traditional watery ascorbic acid formula.
Smuuti uses 3 O ethyl ascorbic acid and ascorbyl glucoside rather than pure ascorbic acid. The brand states that 3 O ethyl ascorbic acid is present at 0.1%, with a smaller amount of the second vitamin C derivative.
The formula also includes niacinamide, panthenol, glutathione, ceramide NP, sodium hyaluronate and oat extract, so it is broader than a single ingredient vitamin C serum.
The brand describes the serum as a rich gel. That means it may feel more substantial than a thin dropper serum, which is worth considering if you layer several leave on products.
Smuuti also notes that the thicker texture can make the dropper slower to fill, so the packaging is part of the buying decision rather than just the ingredient list.
Apply after cleansing and toner, then follow with moisturiser. In the morning, finish with sunscreen. If you already use another vitamin C or brightening serum, there is no need to stack several similar products simply because the ingredients overlap.
