I was pleasantly surprised by how well the MARK Los Angeles XDF-4 After Bite Serum worked. I applied it shortly after a mosquito bite, and the itching and redness started to calm down within minutes. The serum feels lightweight, absorbs quickly, and isn't sticky or greasy. Highly recommend for anyone who wants fast, soothing relief from bug bites!
I prefer it to Caladryl, pimple patches, Aztec clay, EOs, even the Bug Bite Tool. The biggest difference I noticed, besides reduced itch and need to 'slap', was the flatness and lightening of the bite within a few days. I usually have grey skin bruising and hyperpigmentation for a very long time from all the inflammation. I've even let my clients try it out!
I live in rural Arkansas where bugs are rampant and I am a bug magnet. I am allergic to most insect bites. I have tried most products available trying to get relief and this is the first product that consistently works. I am beyond relieved to have found it and would highly recommend it to anyone!
