This product is amazing!!! I have been using for over a year now and was only by chance that i started. Oringnally i thought to put an oil on my problem but mature skin would be the last thing id do but i recieved a sample and afta 3 days i swore id never use anything else and i havnt. I live and swear by this product, it has cleared up my problem spots and my age ones, tightened my skin and its never looked so young and fresh. I glow everyday thanks to trilogys CoQ10 booster serum. Thankyou thankyou thankyou
