I received these products for free for testing purposes and my honest opinion. First off, I thought this was a cool concept. I like that you can talk to an expert and have them come up with a formula personalized for your own individual skin concerns. I have combination skin and very few breakouts. I am definitely looking to keep my skin looking young and wrinkle free. My formulas ended up having some trentinoin, hydroquinone, and hydrocortisone to name a few. I did notice a difference when I started using it. I got a tad sensitive, so the expert kept me on the same formula for the second batch. I’m not sure if this is related, but I’m not sure if these ingredients triggered a cold sore. I haven’t had one for 6 years or so and I’m not sure why it happened, but it made me scared and discontinue the Agency products. If that didn’t happen, I probably would have continued.
