Dot & Key Reworks Its Vitamin C + E Gel Moisturizer Around Four Forms of Vitamin C

Dot & Key has refreshed one of its best-known products, the Vitamin C + E Super Bright Gel Moisturizer, and announced the new formula on 1 September 2026 with a 'Glow With No Filters' campaign starring brand ambassador Aditi Bhatia. The campaign is running on digital and social channels.

The main change is what the brand calls a Quad Vitamin C System, which combines four sources of vitamin C in one gel. Two are lab-made derivatives: THDA (tetrahexyldecyl ascorbate), an oil-soluble form that the brand positions against pigmentation, and ethyl ascorbic acid for brightening. The other two are plant extracts, Kakadu plum and blood orange, which the brand includes for their naturally occurring vitamin C and antioxidant content. Vitamin E and shea butter are also in the formula, and Dot & Key says it helps defend skin against oxidative stress from blue light.

Co-founder and Chief Innovation Officer Anisha Agarwal Saraf presented the update as a way to get visible results without a long routine. She said the four vitamin C types act at different depths of the skin and give a brighter, more even look in a light texture made for daily use. These are the brand's claims, and the announcement doesn't include clinical data or concentrations for any of the four vitamin C sources.

One point for shoppers: this is a moisturiser, not a serum. It can stand in for a serum if you want a one-step morning routine, but a dedicated vitamin C serum usually gives a known, higher dose of the active. The announcement doesn't list price or pack size. Check the label on Nykaa or the Dot & Key site to make sure you're getting the new version, because older stock may still be on sale.
