Just take the plunge!!! I am in love with this set!! The formulation on the night cream is perfectly formulated for my skin, I received the lower does tretinoin because of my tendency towards dryness and I’m so pleased. Not only is my skin texture quickly improving, it is helping with my pesky hormonal acne. I am a skincare hoarder, but I truly believe I am going to be able to streamline my skincare staples, and in that I am very excited how much money this regimen is going to save me. The only thing I would suggest is making the day cream a little larger, as someone who diligently reapplies sunscreen throughout the day I feel I am likely to run out before the 2 month period is up.
