I tried Oleova for my teenage daughters severe acne problem.
The application is twice a day liberally covering the affected area with light massaging by the pads (tips) of the fingers without pressure followed by washing with a mild face wash after two hours.
By the third day all the acne had dried up and redness reduced. By the end of the week, the scars started disappearing and the skin became smooth again. Within 10 days the entire face had healed as if there was never any acne at all.
Since the product is pure Egg Oil and there is no added perfume, there is a slight smell to the product. Also, it must be stored away from light or heat.
