I have been experienced breakout for 5 years and even visited dermatologist but useless. Then my friend recommend Praventac to me so I just take a try. Surprisingly my pimples started dry of itself and leaving a mark after 1 month of time. Well, I’m quite satisfy with this result and considering to combine with Ag-Factor as they said it will speed up the result and lighten up mark scars. This product is highly recommended!!
