"I am beholden to this product and highly recommend it to anyone who needs to camouflage unsightly birthmarks or acne scars. I've tried countless products and none work as well as this product. I award this 5 stars. The 1 oz. jar if used only for the face will last you several months. I use loose powder over it to set the makeup. You can use any brand as long as it's loose powder and it should be applied lightly. Brush off excess with a soft face brush. I have a dark strawberry birthmark below my left eye near the top of my nose that is increasingly getting darker as I age. I do not want to risk skin damage with a laser corrective surgery -- this one works for me. With skillful application of makeup, no one will ever know. Yes, I've fooled everyone -- they think I have great skin!"
