Vitamin C has long been a skincare favourite. Whether you want to brighten a dull-looking complexion, support the look of firmer skin, or help defend against environmental stressors, it's a worthy addition to your routine.
What makes vitamin C special?
Vitamin C, known scientifically as ascorbic acid, is a powerful antioxidant. It helps neutralise free radicals (unstable molecules generated by environmental exposure) and supports the look of a healthy, radiant complexion.
Benefits of vitamin C skincare
1. Brightens dull-looking skin. Vitamin C helps support the look of a brighter, more even tone and the appearance of fewer dark spots.
2. Supports the look of firmness. It's a popular ally for the appearance of plumper skin and softened fine lines, a lovely partner to your anti-ageing routine.
3. Helps defend against environmental stress. While it's not a sunscreen, vitamin C supports your skin's daytime defence, wear it under SPF.
4. Hydration boost. Many vitamin C formulas include hydrating ingredients like hyaluronic acid to keep skin looking plump.
5. Comforting. Vitamin C has a soothing feel that helps calm the look of redness.
When and how to use vitamin C
Vitamin C is most effective in the morning, helping shield skin from daytime oxidative stress (some formulas are made for night use too).
Application: 1) cleanse, 2) tone (optional), 3) apply a few drops of your vitamin C serum, gently pressed in, 4) moisturise, 5) finish with a broad-spectrum SPF in the morning.
Who is vitamin C best for?
Almost all skin types, but especially helpful for those with the look of dull or uneven tone, fine lines, or skin that benefits from a soothing, brightening antioxidant. If your skin is sensitive, start a few times a week and build up.

Choosing a vitamin C product
Look for stable forms like L-ascorbic acid, often paired with vitamin E and ferulic acid to support performance. Always apply SPF daily, as vitamin C routines pair best with good sun protection. Everyone's skin is different, so a little experimentation helps, and consult a professional if you have specific concerns.
Vitamin C + PDRN: a lovely pairing
Vitamin C is great on its own, but pairing it with PDRN salmon DNA rounds out a routine beautifully: vitamin C brightens and supports daytime defence, while PDRN is a gentle hydrator that supports the look of calm, even skin. Use vitamin C in the AM and a PDRN serum AM/PM.
