I have been using ZENMED since 2010 starting at age 60 when I discovered them during an online search for better products and gave them a try. I have Rosacea, love the products, and highly recommend them! 1) The AHA/BHA Complex, which should be used first, helps keep my skin clear and pores unclogged. 2) Next, my most favorite product is the Support Serum - it really helps keep the redness down. 3) The AVT cream is nourishing to my skin and is great for older women like me. 4) I use the Oil-Free Moisturizer with SPF 30 last so the Support Serum & AHA/BHA Complex can be used during the day. It also helps keep acne and other bumps from sprouting, unlike oil-based lotions/creams. There are other products that you may like depending on what you need, but these work best for me! Experiment a bit and you just might find what helps you most!
