Explained
You probably know this ingredient as Thiamidol. It is often called the "hydroquinone alternative".
This ingredient is patented by Beiersdorf - the owner of Nivea, Eucerin, and La Prairie.
Like hydroquinone, this ingredient helps with treating hyperpigmentation. In fact, studies show it works better than traditional hydroquinone.
Thiamidol is a potent tyrosinase inhibitor, meaning it blocks tyrosinase. Tyrosinase is the enzyme used by our bodies to create melanin.
A quick refresher: melanin gives our skin, hair, and eyes pigment or color. Skin exposed to UV will create melanin as a way to protect itself, AKA tanning.
Studies show thiamidol didn't induce the familiar side effects of hydroquinone: redness, itchiness, dryness, and worsening discoloration.
A study from Beiersdorf about the Eucerin Anti-Pigment Dual serum showed hyperpigmentation was reduced up to 75% after 12 weeks of continuous use.
