Tetrahydrocurcumin is widely used in the cosmetic and skincare industry due to its strong antioxidant properties. It helps reduce oxidative stress in the skin, which can slow down the aging process and improve skin elasticity. It is commonly added to anti-aging creams, serums, and lotions for its ability to brighten skin tone and reduce the appearance of dark spots and hyperpigmentation.

In addition, tetrahydrocurcumin is used in pharmaceutical research for its anti-inflammatory effects. It is being studied for potential use in treatments related to metabolic disorders, neurodegenerative diseases, and certain types of cancer due to its ability to modulate cellular pathways involved in inflammation and cell survival.

It is also used as a natural colorant in some food and supplement products, offering a yellow-orange hue without the instability issues of curcumin. Because it is less acidic and more stable than curcumin, it is preferred in formulations where pH sensitivity is a concern.
