So i have sensitive skin and even though I'm young I have laugh lines around my mouth. I used this gel for 2 days, twice a day and already I can see my laugh lines blurring. It doesn't really have any smell so I don't have any bad allergic reaction (Yes I break out if I use products that smell strong). I would not use it under my make up though because even though make up goes on very well after a while there will be tiny white flakes around your nose.

Over all, love it and will repurchase!!
