Noelani Gonzalez, a dermatology specialist at Mount Sinai Health System. Because it contains a similar formula to the SkinCeuticals C E Ferulic, you get all the skin-brightening benefits at “half the cost,” according to Dr. Ingredients: Contains L-ascorbic acid, ferulic acid, and vitamin E | Formulation: 15 percent vitamin C | Packaging: Opaque bottleįor a more affordable option, two of our dermatologists recommended Drunk Elephant’s C-Firma Day Serum. “That way a reservoir of active vitamin C is present in the skin during the daylight hours, when ultraviolet radiation is strongest,” he explains. Whatever vitamin-C serum you choose, Howe suggests applying it in the morning. Julie Russak, founder of the Russak Dermatology Group, puts it, this serum “delivers vitamin C through the top layer without disrupting the protective barrier of the skin.” Part of this serum’s patented formula includes a pH level higher than those of its competitors, meaning it won’t cause the redness and sensitivity that serums with a lower pH can. Its main active ingredient is L-ascorbic acid (it comprises 15 percent of this serum) and despite the high concentration of pure vitamin C, it is both stable and easily penetrates the skin. It is expensive but worth the price due to its super-stable, patented formula. It sits seamlessly underneath my other skin care and even layers well under makeup. He says it has a light, non-greasy feel, while still delivering “the maximum amount of its active ingredients to the skin.” I’ve also used C E Ferulic off and on for the past few years and can confirm its light consistency. “I think it’s the best out there,” declares Howe. Ingredients: Contains L-ascorbic acid, ferulic acid, and vitamin E | Formulation: 15 percent vitamin C | Packaging: Translucent amber bottleįour of our dermatologists recommend SkinCeuticals C E Ferulic, which they (and our editors) hail as the gold-standard vitamin-C serum and is suitable for all skin types. In recent years, products have come out containing both L-ascorbic and an accompanying derivative, which combines the unstable formulation with a more stable formulation - offering the best of both worlds. The vitamin-C derivatives also easily penetrate the skin because the skin has a lipid barrier (think: oil dissolves oil), so there’s not as much resistance to the ingredients as something water soluble (like L-ascorbic acid). Unlike L-ascorbic acid, which is water soluble, THD-ascorbate is oil soluble and can be easily added into an oil-based product. One of the most popular derivatives is tetrahexyldecyl ascorbate (often called THD-ascorbate), which is marketed as a more tolerable alternative that offers similar results. They have to be converted to the active form and are less potent than the pure, active ingredient.” The difference between pure vitamin C and vitamin-C derivatives is similar to retinols and retinoids: Both work, but one is more concentrated and thus more effective. “L-ascorbic acid is the most active form of vitamin C, whereas the derivatives are inactive. Karan Lal says are “less irritating and more tolerable and more stable” forms of vitamin C. If you fall into that category, are just starting out, or have sensitive skin, you can try vitamin-C derivatives, which Dr. While incredibly effective, it can be irritating for some people and even cause acne.

Our picks - organized by skin needs - are below. To find the best of the best, I spoke to dermatologists, aestheticians, and Strategist staffers who moonlight as skin-care enthusiasts, and tested a bunch myself. That’s why it’s important to find the right formulation - one that makes vitamin C as stable as possible while also delivering it effectively to the skin. Despite its efficacy, vitamin C is notoriously unstable and can quickly go from a hyperpigmentation-zapping wonder ingredient to a $60 bottle of smelly serum. It’s also why there are so many products to choose from. It’s incredibly effective at all of this, which is why so many people use and recommend it. The antioxidant promises everything from fading dark marks to fighting free radicals (which break down collagen) to diminishing fine lines and wrinkles. But vitamin C is one of those actually necessary ingredients. As someone with a fairly minimal skin-care routine, it’s difficult to convince me to add a new product or step.
