Ayesha, a reviewer, shares her experience with the Killa Kit - Deep Zit Microdart Patch 8pk by ZITSTICKA. She highly recommends this 2-step product for those struggling with under the skin zits. The first step involves using the Cleaner Cleaning Swab to clean the affected area and letting it dry for 15 seconds. The second step is to apply the Killah Patch onto the zit, holding it for 30 seconds, and leaving it on for at least 2 hours, or even overnight. Ayesha noticed a significant reduction in size and redness after using the patch. Overall, the Killa Kit offers an effective solution for combating under the skin zits.
