2,000-year-old skincare tradition uses tree bark

Thanaka is a traditional skincare product made from tree bark. For thousands of years, people in Myanmar have been using thanaka to protect and care for their skin. It's worn by both adults and children. Thanaka paste is made from the bark of wood-apple trees. The paste is formed by grinding the bark on a stone slab with water. Thanaka is applied on the face and is believed to act as a natural sunscreen, bug repellent, and acne treatment.
