What this means for you
What people love
- Brightening that visibly helps acne and dullness
- Reduced hyperpigmentation, evened tone, smoother texture
- One user reported curing longstanding atopic dermatitis
Watch out for

What the science says
Hyperpigmentation
Some evidence
Vitamin C: 9 studies tested it directly. See all 19 studies
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
- It did not clearly beat a placebo for how much water the skin held
- No irritation or sensitivity was reported in one study
