Can be used both day and night.

"I can be really sensitive, but this serum is effective without causing any redness. Would definitely recommend"
— Ursula C. (5/5)
"Just switched to this from Pareva and so far so goo. It goes on smooth lays nicely under my other serums and makeup."
— Lisa C. (4/5)
"Great product, been using this brand for years now and just recently switched over from their OG product to try this more gentle serum out and am enjoying it. It's more tame-feeling and BONUS the "bacon" smell of the original Vit. C product from MVO is not present. Woohoo. No bacon smell."
— Chrissy C. (5/5)
"It’s a little less sticky than the popular skinceuticals version, which I like, and it really works on discoloration and stops oil from oxidizing in pores."
— Summer S. (5/5)
"Traditional Vitamin C serums always leave my face red and burning, but the Marie Veronique C-Therapy Serum is an absolute game-changer"
— Priyanka B. (5/5)
"I LOVE this serum. I get my topical vitamin C in a luxurious serum and it doesn’t break me out!"
— Elizabeth F. (5/5)
"If you don't drink enough water or have a large arsenal of beauty products to maintain that healthy glow and plump skin this is your product. It's solid!"
— Freddy C. (4/5)
"Most vitamin c products are too harsh for my rosacea prone skin, but I have been tolerating this well by easing it to my routine. Short term I notice this is helping to give me a subtle glow — long term I hope to see improvements with pigmentation, but time will tell. This is a pricey serum and the vitamin c serum smell may be off putting for some but I prefer that to having any essential oils or fragrance to contend with."
— Sarah L. (4/5)
"I love this serum! I have incredibly sensitive skin, and it brightens without breaking me out!"
— Elizabeth H. (5/5)
"I usually use the C and E Ferulic Acid but they were out. In a pinch this gets the job done. MV is great quality skincare. This has been part of my routine for years."
— Marina B. (5/5)
