Charcoal has been used medicinally for millennia. Way before the refrigerator, our grandmothers used charcoal to preserve soups and I quite remember the powdered charcoal been used for brushing the teeth, it was also used for water filtration.
Charcoal draws bacteria, poisons, chemicals, dirt and other micro-particles to the surface of the skin, helping it to achieve a flawless complexion and fight against acne. Charcoal is not absorbed by the skin, but it can be used to treat some poisonous bites and disinfect some wounds.
Facial products that contain charcoal are very effective for skin treatments. Natural remedies for skin treatments are very effective, but the key to their effectiveness is consistency.
