If there is one active that dermatologists, skincare lovers and the "minimalist" routines of summer 2026 all agree on, it is vitamin C. Loved for its immediate radiance effect and its role as an antioxidant shield, it is one of those ingredients worth knowing well before adding to your routine. In this article we look at what it is, how it acts on the skin's appearance and how to use it at its best, sun included.
What vitamin C is
Vitamin C (ascorbic acid and its more stable derivatives) is a molecule with marked antioxidant properties. In cosmetics it is used in various forms and concentrations precisely for its ability to contribute to a radiant, even-looking complexion. It is a "multitasking" active: it works on the complexion, on the evenness of the tone and on the feeling of fresh, revitalised skin.
Modern formulations often pair vitamin C with other complementary ingredients, such as niacinamide, whose multitasking action on skin texture and shine we have explored in depth, for more complete action on the evenness of the complexion.
How it works: the benefits for the skin's appearance
Vitamin C's strong point is its antioxidant action: it helps counteract the oxidative stress caused by environmental factors such as pollution and UV rays, which over time contribute to a dull, uneven-looking skin. Adding it to your routine means giving the skin daily support against these factors.
- Radiance: it contributes to a brighter, more "awake" complexion.
- Even tone: it helps improve the appearance of discolouration and surface dark spots.
- Antioxidant defence: it helps counteract the free radicals generated by environmental exposure.
- A firm look: it is often associated with skin that looks more toned and fresh.
Vitamin C and summer: can they be used together?
It is one of the most common doubts of the moment. The answer is yes: vitamin C is a precious ally precisely in the warm months, because its antioxidant action helps counteract the oxidative stress linked to sun exposure. It does not replace sun protection, it works alongside it: this is why summer's winning combination is vitamin C in the morning + SPF. If you still have doubts about when and how much to use it, we have dismantled the most widespread myths about sun protection. Store your products away from light and heat to best preserve their effectiveness.
How to add it to your routine
Vitamin C performs at its best in the morning routine, when its antioxidant role accompanies the skin through the day. The essential scheme, in line with the "skin minimalism" approach so loved this season, is simple:
- Cleanse your face and pat gently dry.
- Apply the vitamin C serum or booster to clean skin.
- Follow with your moisturising cream.
- Always finish with broad-spectrum sun protection: the American Academy of Dermatology recommends choosing SPF 30 or higher and reapplying it roughly every two hours when outdoors.
If you have sensitive skin, start with lower concentrations and an application every other day, gradually increasing the frequency according to tolerance. Consistency, more than concentration, makes the difference in the skin's appearance.
