by TruSkin
Updated October 9, 2026
Gentle vitamin C derivative for slow brightening; underrated AM staple.
What the community says
A sodium ascorbyl phosphate serum with aloe, glycerin, sodium hyaluronate, and tocopheryl acetate for AM layering. People use it on rotation with tretinoin or for gradual brightening, but the formula is meh if you want fast results.

- Gentle vitamin C derivative
- AM layering with aloe, glycerin, and sodium hyaluronate

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.
