Shortened how long my blemishes last considerably. Smells like lavender which is some nice aromatherapy right before bed.
I wish it would prevent blemishes along with just fighting pre-existing ones. I've noticed a difference in how long my blemishes take to heal and go down, but not in the frequency I get blemishes.
I spot treat my spots and let it sit a little before I rub it in with my moisturizer.
