Questions and answers

What does thiamidol do for the skin?

Thiamidol significantly improves facial hyperpigmentation, melasma, and post-inflammatory hyperpigmentation by helping to inhibit tyrosinase. Clinical studies show it helps lighten dark spots and improves skin tone effectively.

How do you use thiamidol?

Thiamidol may be applied up to four times daily to significantly improve facial hyperpigmentation.

International Journal of Cosmetic Science, 2020

Should you use thiamidol in the morning or at night?

Thiamidol may be applied both morning and night as part of a regular routine, with studies evaluating consistent daily use for facial hyperpigmentation.

International Journal of Cosmetic Science, 2020

Can you use thiamidol every day?

Yes, you can use thiamidol daily, and applying it four times a day may improve facial hyperpigmentation significantly more than applying it twice daily.

International Journal of Cosmetic Science, 2020

Does thiamidol cause purging or irritation?

Thiamidol is unlikely to cause purging since it is a tyrosinase inhibitor that targets hyperpigmentation rather than speeding up cell turnover. Mild irritation may occur depending on individual skin sensitivity.

Which skin types is thiamidol best for?

Thiamidol is best for oily, acne-prone, combination, sensitive, and mature skin, as well as skin with dark spots, with specific top-rated products like Eucerin DermoPurifyer Triple Effect Serum and Eucerin Sun Face Pigment Control SPF50+ achieving Superior or High fit ratings on Lovi.
