Highlights

Suitable for

All skin types. Safe for sensitive skin.

Why we stand behind it

This gentle-yet-powerful serum contains four powerful derivatives of vitamin C that are better suited to sensitive skin than l-ascorbic acid but deliver the same results: collagen production, antioxidant protection, and visible skin brightening.

This formula includes antioxidants glutathione and alpha-lipoic acid that help to protect the mitochondria, resulting in improved skin brightness and anti-aging benefits.

Can be used both day and night.

Key ingredients

Sodium ascorbyl phosphate: Prevents oxidation of debris in congested pores to clear and prevent breakouts.
Glyceryl ascorbate: Moisturizes to improve barrier function, provides sun protection, brightens skin.
Magnesium ascorbyl phosphate and tetrahexydecyl ascorbate: Provide anti-aging effects like collagen production enhancement and impede hyperpigmentation processes.
Alpha-lipoic acid and glutathione: Powerful antioxidants to help prevent damage to mitochondrial DNA.

What is an undertone?

An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:

Pink/Cool

I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.

Neutral

I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.

Yellow/Warm

I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

Reviews

Smooth, Calming and less Irritating

"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)

Finally a Vitamin C my sensitive skin loves!

"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)

Best C Serum I’ve used-no breakouts

"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)

Good for dehydrated skin types

"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)

Gentle Vitamin C glow

"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)

Great for Sensitive Skin

"I love this serum! I have incredibly sensitive skin, and it brightens without breaking me out!"

— Elizabeth H. (5/5)

Can't go Wrong with MV

"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)

Could not get past the smell

"Not sure if it was this batch or what, but it smelled rancid, like rotten oranges left on the counter for a few days. I did like it did not make my skin itchy like some Vitamin Cs can, but the smell is horrid."

— Jandi O. (2/5)

So far so good

"Vitamin C serums are always recommended as an essential step, so I have been trying this one. The texture is nice, I’m not sure if I can see a noticeable difference in my skin."

— Tracy H. (4/5)

Love it

"Been using this product for 2 years and love it. Although sometimes it's hard to get at CREDO stores and online, others must love it too, because it's often sold out."

— Laura N. (5/5)
