I have tried so many facial primers that were so disappointing and resulted in no change at all. Sheglams Birthday Skin Primer is outstanding. The formula is smooth and hydrating, melts into skin, dries down quickly and delivers a beautiful blurring effect for flawless skin. The change is noticed immediately and perfects application of your foundation or can even be worn alone. I am truly impressed, and you will be too. Highly recommend. I have found my new Holy Grail!!
