Vitamin C Serum — Reddit Reviews
by Trader Joe's
Updated October 28, 2026
15% ascorbic acid fades discoloration and dullness; sticky, oxidation-prone formula.
What the community says
A 15% ascorbic acid serum with ferulic acid, tocopherol, glycerin, and sodium hyaluronate targets dullness and leftover marks. Best for experienced vitamin C users wanting a cheap morning active; sticky layering, eyelid burning, and oxidation frustrate reactive skin.

What the studies found
- Most studies found vitamin C helped fade dark patches, especially melasma
- It often worked better than a placebo when put on the skin for melasma
- Used with microneedling or peels, it often improved dark patches more
- Some studies found it worked about as well as other dark-spot treatments, not better
- The side effects were usually mild and brief
Anti-Aging
Some evidence
Vitamin C: 4 studies tested it directly. See all 12 studies
What the studies found
- All 4 studies that tested it directly found it helped with signs of aging
- It improved the look and texture of sun-damaged skin more than a placebo
- It helped smooth wrinkles, roughness, crow’s-feet, and uneven skin tone
