🧬 Why Is Potato Juice a Skin Brightening Secret?
Potato juice, long used in traditional beauty rituals, is now gaining scientific attention for its skin-brightening, anti-pigmentation, and anti-inflammatory effects. Rich in vitamin C, catecholase enzymes, potassium, and antioxidants, potato juice acts on melanin production and oxidative stress—the main culprits behind dull skin, dark spots, and hyperpigmentation.
🧪 Science says: A study published in the International Journal of Cosmetic Science suggests that natural antioxidants and enzymes like catecholase can modulate pigmentation and reduce skin dullness over time.
