What is Thiamidol?
Benefits, Uses & Skincare Guide
Thiamidol is a patented skincare ingredient that is specifically formulated to reduce melanin production, which can create dark spots, hyperpigmentation, and an uneven skin tone. The latest research has shown that Thiamidol is one of the most effective ingredients for reducing dark spots*, outperforming many common anti-spot ingredients. Used in NIVEA LUMINOUS630® products, Thiamidol works at the root of dark spots to reveal a luminous, even-toned complexion** that you can feel confident in every day.
*In vitro tested vs the most common anti-spot ingredients in the face care market.
**Dark spots caused by sun exposure, ageing, and hormonal imbalances like pregnancy and menopause.
How Does
Thiamidol Work?

Thiamidol helps reduce dark spots by balancing pigmentation. With regular use, you can see existing dark spots become lighter and also help prevent new ones from forming.
Understanding melanin production:
Melanin is the pigment responsible for your skin colour.
Pigmentation occurs when the enzyme tyrosinase converts the amino acid tyrosine into melanin. Increased unprotected sun exposure or other factors can activate this enzyme more, which can result in uneven-looking skin.
Factors affecting melanin production:
Unbalanced melanin production can lead to dark spots.
Hormonal changes and ageing can trigger melanin production.
Unprotected sun exposure
Researchers found that Thiamidol in LUMINOUS630® ANTISPOT helps inhibit tyrosinase, balances pigmentation and therefore effectively lightens dark spots.
The Thiamidol
Clinical Study
Our research teams carried out numerous compound tests to find the most effective ingredient against dark spots. And the findings? Number 630, Thiamidol, turned out to be the most effective on tyrosinase, an enzyme involved in skin pigmentation.
When the LUMINOUS630® ANTISPOT DARK SPOT ADVANCED SERUM containing Thiamidol was consistently applied to the skin, it was noted that:
- The first visible results were seen in 7 days*
- Spot intensity was reduced by 82% in 8 weeks**
Clinically tested, it not only reduces the appearance of visible spots but also dark spots you can't yet see, which might become visible later on.
