We tested 5 dark spot treatments featuring resorcinol derivatives and 2 stood out.
One features thiamidol, with research supporting its role in preventing UV-induced pigmentation and treating post-acne marks.
Another uses hexylresorcinol, supported by clinical testing across different types of hyperpigmentation.
The key takeaway: it’s not just about the ingredient — the testing behind the formula matters.
And don’t forget: consistency is key. Most hyperpigmentation treatments require at least 12 weeks to see visible results, along with daily sunscreen use.
