I used to take Nutrigold Coq10 but upgraded to this brand because I wanted to switch from the inactive quinone vartety to the active quinol version of the supplement in order to aid my heart and kidney conditions. . I am pleased with the improvement, quality and price. I've noticed that a side effect is that this CoQ10 moisturizes my skin. I researched the correlation on health sites and confirmed that skin improvement is indeed a benefit of CoQ10. It has improved my skin condition, moisture and tone. I'm sure the fatty acid base increases these skin effects, but is causing my face to be oily, which clogs my pores and causes me to break out with Acne. The Nutrigold had an organic olive oil base which did not break me out. I'm not going to stop using it just yet because I like the other effects. However, I'm a bit disappointed so I subtracted a star. I'd like to hear if others have experienced Acne from this product
