Discoloration Defense — Reddit Reviews
Updated September 2, 2026
Tranexamic acid and niacinamide lighten hyperpigmentation and acne scars effectively; pricey.
What the community says
This serum features 3% tranexamic acid and 5% niacinamide for fading post-acne marks and hyperpigmentation. It's gentle enough to pair with actives but is expensive and works best used consistently over time. Kojic acid was removed in some batches.
