QUICK ANSWER
Vitamin C is an antioxidant that helps defend skin against environmental stressors like pollution and UV-induced free radicals. Used topically and consistently, it is best known for helping brighten the look of dull, tired skin, supporting a more even-looking tone, and helping skin look firmer and more radiant. It works best alongside daily sunscreen.
What Is Vitamin C?
Vitamin C is one of skincare's most-studied antioxidants. Antioxidants help neutralise free radicals, the unstable molecules created by UV and pollution that contribute to the look of premature ageing and dullness. Topically, vitamin C is used mainly to support a brighter, more even-looking, healthy-looking complexion. It comes in several forms, from pure ascorbic acid to gentler derivatives and natural sources like Kakadu Plum.
What Vitamin C Does for Your Skin
Here is what vitamin C is genuinely valued for, in honest, everyday terms:
- Brightens the look of dull skin: it helps tired, lacklustre skin look more radiant.
- Supports a more even-looking tone: with consistent use, skin can look more even and fresh.
- Antioxidant defence: it helps defend skin against daily environmental stressors like pollution and UV-induced free radicals.
- Firmer, plumper-looking skin: over time it can help skin look firmer and plumper.
- A smoother, healthy-looking finish: it supports an overall smooth, glowing appearance.
A quick reality check: vitamin C is a supportive, brightening ingredient, not a medical treatment, and results build gradually with consistent use rather than overnight.
The Forms of Vitamin C
Not all vitamin C is the same, and the form affects how potent and how gentle it is:
- L-ascorbic acid: the purest, most potent form; effective but less stable and better for skin used to actives.
- THD ascorbate: an oil-soluble, stable, gentle form that suits daily use and sensitive skin.
- Sodium and magnesium ascorbyl phosphate: gentle, stable derivatives, kind to reactive skin.
- Kakadu Plum: a native Australian superfruit and one of the richest natural sources of vitamin C, used across much of the LAMAV range.
Who Vitamin C Suits
Most skin types can enjoy vitamin C, the trick is matching the form to your skin. Sensitive or reactive skin does best with gentler, stable forms or natural Kakadu Plum, introduced slowly. Oily and combination skin tend to like lightweight serums and fluids, while drier skin may prefer vitamin C in an oil or a cream. If your skin is very reactive, patch test first and build up gradually.
