this review title is: great way to test both of these products before spending over for each of them and the content is: i bought these as a recommendation from my functional medicine doc who only works with organic products and i could not believe the full product was almost but if it is worth it i will do it and this was a great way to test it without spending all that initially i have very oily skin so i did not use the yellow one too much but i really do like the pink glycolic night serum.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
