Oh great, the pimple is gone! And what do we do with the red marks left by the pimple? No need to worry, because you have Postzit in your group. The serum is based on glycolic acid, which minimizes pimple marks (hyperpigmentation), improves skin texture and evens skin tone. And in case there are still stubborn spots, we have added salicylic acid and Quora Noni PRCF, the real hacker of acne-causing p.acnes bacteria, preventing them from multiplying and rebalancing the skin's microbiome. In addition, the acids contained in this formula have been developed with Nichosome, an exclusive active ingredient release system that ensures that our products do not irritate the skin while delivering up to 12 times more active ingredients to the area of skin to be treated than when used without our active ingredient release system (wow!), thus increasing the effectiveness of our formulas incredibly. When to use : Use it after Zitclean and before Zicontrol on the reddish marks that some spots leave behind once they have disappeared. You can combine it with : Zitcontrol to reduce the appearance of breakouts and to prevent new pimples.
