I have been using Alpha brand for some time now. It is affordable and works well. I first began using a dermatologist brand 35 years go for adult acne. People, including doctors, tell me I look at least 10 years younger than I am, my neck is not wrinkled. I also use it on my legs and arms to lighten blemishes caused by allergies to insect bites, plants, grasses, and scratches. This product is excellent for me.
