    Game changer

    This product helped clear my acne and reduce my acne scars. I’ve been using it for years and when I first started I had pretty bad breakouts. Now I rarely break out, a pimple here or there when I’m on my period or something, and the acne scars have faded.

    Good investment

    Really struggle with oil and greasy looking skin, since using this, oil has reduced along with redness. I only apply to my T-Zone as I found it dried the rest of my skin out.
