When we spoke to dermatologists and beauty experts about the best vitamin C serums, Drunk Elephant’s C-Firma Day Serum was recommended. Its formula contains L-ascorbic acid, as well as pumpkin-ferment extract and pomegranate enzyme, which attack dead surface skin cells and help to exfoliate, explained Dr. Deanne Mraz Robinson, a co-founder of Modern Dermatology of Connecticut and skin-care company PURE BioDerm. Plus, the serum’s packaging is both airtight and completely opaque — things Gonzalez says you should look for when choosing a serum, because packaging like this helps to keep the vitamin C from exposure to water, light, or oxygen (all of which degrade it).

Strategist UK contributor Natalya Lobanova is also a fan: “Every time I run out of this serum I try to put off buying a new one — parting with £67 for a single skin-care product always feels a little painful. I try to convince myself that I don’t need it, that my skin is fine without it. Then a few weeks later, with some dark pigmentation spots that just won’t fade, weird dry patches, and far bumpier skin texture, I place another order. Although, it brings me some comfort to note that £67 divided by 90 days is just 75p per day — a small price to pay for luminous skin, and a lot cheaper than a daily coffee.”

The serum is a healthy 20 percent off at Cult Beauty for one day only: It’s £54, down from £67. One last enticement? As the purchase is over £50, you can avail yourself of two free samples at checkout: the current options include Davines, Christian Louboutin, and Votary.
