I recomand this product it’s very good brand. Mostly I used blue heaven water proof pan stick .This stick provide you a youthful grow .I told u how we can use it .Apply concealer stick under your liquid foundation, pan stick or powder. Apply to the dark circles under the eyes by taking a little concealer stick on your index fingertip nd applying lightly to the dark circles. Stroke lightly to blend evely over dark circles. Repeat with the other eye. You can apply this concealer as a base before applying your foundation. After concealer stick is applied, make up your face in normal way. Thankio
