I got this sample size and tried it for the past 3 days. I mix a small amount with my facial cleanser and gently massage all over. My face hasn't looked this good in months! Skin feels smooth and soft. Forehead acne totally gone. One of the keys here, folks, is GENTLY massage over skin. When people say it's too harsh, they could be rubbing too hard. I did that the first day and ouch! But wow! What a difference doing it correctly! Give it a try!! I will be purchasing the full size!
