Frankincense

Frankincense, from the Old French expression "franc ecens" meaning 'true', 'high quality' or 'pure' incense, has been traded for more than 5000 years.
This precious resin has been noted for its skin healing properties including reduction of wrinkles, lines, scars & stretchmarks, prevention & fading of sunspots, new cell generation, skin tone improvement, reduction in pore appearance, skin elasticity maintenance & soothing dry & chapped skin (22).
The aromatherapeutic properties of Frankincense include relaxing, rejuvenating, confidence boosting & easing stress (23).
