There isn't a specific type of turmeric that's better for skin whitening than others. Turmeric's potential for brightening skin comes from the curcumin compound it contains. All types of turmeric, whether fresh, powdered, or extract, contain curcumin.
However, curcumin absorption can be a factor in its effectiveness. Some suggest that fresh turmeric might be more effective than powdered turmeric due to potential differences in curcumin bioavailability. This means the body might absorb and utilize the curcumin from fresh turmeric more readily.
Ultimately, the "best" turmeric for skin whitening depends on your individual needs and preferences. You can experiment with different forms of turmeric, including fresh, powdered, and extract, to find what works best for you.
It's essential to use turmeric in moderation, as excessive use can lead to skin irritation or staining. Always perform a patch test before applying turmeric directly to your face or body.
