I have extremely sensitive, acne prone scared so I was honestly scared to try this but I had wanted a retinol in my routine and needed to fade dark spots. I received a 3 month free trial and I've been very impressed so far. Didn't dry my skin out at all, didn't irritate my sensative skin and I had pimples that wouldn't come to the surface and this made it happen. It didn't cause any new acne just really cleared out the acne I was struggling with. While my skin isn't perfect now especially because my break outs are Hormonal these products have helped so much and I'll definitely be purchasing these on my own in the future.
