I use the serum, suncream and rescue cream. All the products suit my skin so we'll and have helped to heal a very itchy red area from the bottom of my nose down to my mouth. I had tried many other creams/treatments before this and these are the only products that have not irritated it. If it flares up a bit I use the rescue balm on that area overnight which gets it back on track. The rescue balm didn't suit my whole face, I have an oily complexion, so I just use it on the areas that really need it and that works well. To maintain it i use the rescue cream every night and this works besutifully on my whole fsce as its less oily. Highly recommend the products. The testers you can get are a really decent size and last long enough to give you a feel as to whether the product suits you.
