I use this product everyday as part of my AM skin care routine. After cleansing, I use the Montarbo brand vitamin C serum, then use Cera-Ve Am moisturizer which has it's own SPF35. I wait until that dries and then come back for a layer of Montarbo SPF product. Maybe this is overkill, but I do not have any problems with the product building up and rolling. Most days I wear makeup over and do not have congestion nor do I look overly "dewy". Using this product I think helps to smooth out the whiteness from the Cera-Ve moisturizer! I will continue to use this product in my solar rays defense battle plan forever and ever, Amen. Thank you Cody Montarbo for creating a product that is clean and not full of BS fillers and perfumes. I <3 Montarbo Skin Care!
