Scientific Conclusion
Mixing coffee with Vaseline creates a simple exfoliating and moisturizing scrub that may temporarily soften and smooth the skin. Coffee provides physical exfoliation and antioxidant compounds, while petroleum jelly helps reduce moisture loss.
However, scientific evidence does not support many exaggerated online claims about permanent skin whitening, wrinkle removal, or dramatic anti-aging effects. Dermatologists recommend careful use, especially for sensitive or acne-prone skin.
