C-Niacin Toning Ampoule
A lightweight brightening ampoule that pairs a stable vitamin C derivative with niacinamide to even out tone. It is watery and sinks in fast, slotting easily between toner and moisturizer without feeling tacky. A sensible choice for normal to oily skin dealing with dullness or lingering dark spots that wants tone care without the sting of a high-strength pure vitamin C.
More detail
The vitamin C here is 3-O-ethyl ascorbic acid, a stable and gentle form of vitamin C, working alongside niacinamide (placed high in the formula) to brighten and fade uneven tone and post-blemish marks. A base of sea-buckthorn fruit extract adds vitamin-rich antioxidants, while aloe, licorice-root extract, panthenol, allantoin, and beta-glucan keep it soothing and hydrating. The texture is a thin, fast-absorbing ampoule that layers well under moisturizer. Use a few drops after cleansing and toner, morning or night; if you apply it in the morning, follow with sunscreen, since brightening routines make daily SPF important. It is a mild formula, but if you are new to vitamin C it is still worth a patch test.
