- 4-butylresorcinol
A study combining laboratory work with vehicle-controlled age-spot testing reported visible improvement on forearms within eight weeks. The abstract does not give the human sample size or establish randomisation and blinding.
Laboratory and human research
4-n-butylresorcinol, a highly effective tyrosinase inhibitor for the topical treatment of hyperpigmentation.
- Acetyl Glucosamine
A trial measured facial pigmentation with 2% N-acetyl glucosamine and 4% niacinamide in a skincare regimen that included an SPF lotion. It cannot isolate either ingredient's effect.
- Niacinamide
In 18 Japanese participants, 5% niacinamide reduced hyperpigmentation relative to its vehicle after four weeks. The selected population and formula do not establish equivalent results for every niacinamide product.
Laboratory and human research
The effect of niacinamide on reducing cutaneous pigmentation and suppression of melanosome transfer.
