The masks are great and make your complexion really bright. In addition, they work as a fantastic relaxing moment in your day. I think they're optimal if you have an event to prep your skin before moisture and make up. The great thing is the booster because it creates almost the same effect and it's easier and faster than the mask. You can add reallly just one or two drops to your moisturizer and it works really well since the very first application. Obviously it does not alter the texture of your skin, but it makes it radiant and bright (without a too shiny effect). Moreover, I have very sensitive skin, and did not have any bad reaction. I think the booster can last long and makes the overall pack not as pricy as it seems.
I would strongly recommend it.
