Buying facial products is a vice of mine.
Like tons of people have already stated: drink plenty of water. That is the biggest factor overall.
I've had a Clarisonic Plus for a few years now and I love it. All of the models are great. They're expensive but 100% worth it, in my opinion. I can never go back to washing my face with just my hands and or a wash cloth. The difference in cleansing really is substantial. I would highly recommend them to anyone. The cheap knock offs for 15-30 bucks aren't worth it and will just rip up your face so don't go for them.
I love products from Paula's Choice. They don't have any fragrance and they don't animal test. They have multiple lines and they're all great but I go for the big pricier Resist line because it has added antioxidants and anti-aging ingredients. Plus, the cleanser, serum and moisturizer are all so silky and feel amazing on my skin.
