I use only the tiniest drop (not even a full pump, you really don't need much) with two pumps of the Instant Perfection Serum and mix it in my palm before applying it to my face in the mornings after I've used Omoressence. It actually gives a 'boost' in brightness and radiance - my skin tends to look very dull - and in combination with the serum, I don't need a moisturizer right now which is a blessing in this heat! (My skin is very oily yet needs a lot of moisture) It does everything it claimed it would. I'm sure I'll keep using it in winter, too, then probably followed by a moisturizer. I've been using this for about 6 weeks now and haven't run out yet. Probably not an absolutely essential product, but perfect for me.

The booster felt very sticky on my skin. This needs to be applied to the completely dry skin, otherwise, it would foam slightly and prickle. Also, it was uncomfortable to apply moisturizer to it. A really weird product that did nothing for my skin. Also, the pump broke two weeks in, and there was no way to get to the rest of the product. I'm the biggest Omorovicza fan, but this was a waste of money for me.

I liked this, or at least thought I might and then it ran out. It really is tiny and using even just one drop a time, it lasted some two weeks or so. Too expensive per drop for me.

The only word to describe this product. My skin looks instantly brighter and radiant immediately after use!

This was an impulse buy when the free Thermal Cleanser promo was on (i was left wondering why i'd ordered this in particular - it's brand new and no online reviews, I like to wait). i regret nothing. It really does do everything it promises in the short term. I'm not sure about long term as yet but it does take away the need for any tinted moisturiser/balm in the mornings.
