This is a product I feel I would need to use for a few weeks in order to give it a good honest review. I do like the brand and ingredients.

New part of skincare routine

I have enjoyed this sample. It is really light and goes on softly and smoothly. It adds nutrients to my skin and makes my skin feel good. I haven't seen its effects of toning and brightening yet though, which is why I rated it a 4.

I am now obsessed with this product, bought it immediately !! It is a miracle! Somehow it brought life to my face and was so pretty just by itself without any makeup on top.

big difference

I started using this product as soon as i got it in my box. I noticed a difference immediately. It works very well and i love how smooth it goes on. It acts as a primer for the lines on my forehead. I would highly recommend it.
