No products have really worked on my hormonal acne until I started using the A-sol. I use it as a spot treatment after cleansing and wait 10 minutes for it to dry. It flattens small pimples overnight and even helps shrink cysts. I'm really amazed by how well this works. It also lasts a really long time - one bottle lasted me over six months. It does have a really strong, fishy smell until it dries down, though. Also, the pump is kind of annoying because a lot of product ends up running through your fingers. I strongly recommend this product to anyone who struggles with acne.
