5% THD vitamin C with ceramides for gentle brightening; YMMV on acne.

What this means for you
What people love
- 5% THD vitamin C — the gentle starter pick

Some evidence
Vitamin C: 7 studies tested it on its own. See all 24 studies
What the studies found
- Most studies found vitamin C helped fade dark patches or spots
- Studies in melasma found vitamin C on the skin made patches look lighter over time
- Used with other treatments, vitamin C often faded dark patches more than the other treatment alone
- Vitamin C worked about as well as glycolic acid for fading dark patches in melasma
- One study in sun spots found only weak fading, with mixed results across different skin-darkness scores
Research context, not treatment advice. Studies are about the ingredient, not necessarily this exact product.
