My first purchase from Jersey Beauty Company as they offer the cheapest Dermalogica prices around! I'm absolutely in love with this serum - at first I didn't think it was doing any good, but now I wouldn't live without it! It works like a sneaky little shark, secretly improving your skin on the sly and suddenly making every other product work 100% better because your skin barrier is actually able to fully absorb the products! I am a huge, huge fan and have put so many friends on to it who are experiencing great results too! There's no other serum like it!
