My Favorite Vitamin C
"I have tried a bunch of vitamin c serums and this one is my favorite. It does not irritate my skin or cause redness and it is potent. You do have to mix the two containers together - I think it's a fun science project."

Why we stand behind it
This supercharged daily brightening serum contains 20% L-ascorbic acid—a potent dose of the purest form of vitamin C—to visibly target dullness and discoloration. Skin-smoothing ectoin, an antioxidant powerhouse, is synergistically combined with ferulic acid to improve the look of skin tone and texture. Goop's serum is developed with a unique two-part system featuring a hydrating hyaluronic acid serum activator and is designed to be mixed before the first use to maximize performance and freshness. The result is noticeably smoother, softer skin with a remarkable glow.*
Clinical measurements taken after four weeks of twice-daily use on 32 subjects between the ages of 30 and 55. Based on a four-week third-party consumer-perception study of 32 subjects between the ages of 30 and 55.
Key ingredients
L-Ascorbic Acid: purest form of vitamin C and a super potent antioxidant. This high concentration protects against damaging free radicals and improves the tone, texture, and clarity of skin for visibly radiant complexion.
Ectoin: soothing extremolyte with antioxidant properties to protect against oxidative stress and support the skin barrier by preventing trans epidermal water loss.
Ferulic Acid: strong antioxidant that targets fine lines and wrinkles, hyperpigmentation, and signs of aging by neutralizing free radicals from UV and environmental stress.
Kakadu Plum Extract: with one of the highest naturally occuring sources of vitamin C, this extract is also rich in flavonoids and phenolic, which help stimulate the product of collagen, reduce fine lines and wrinkles, and reduce the appearance of hyperpigmentation.
Tri-Molecular Weight Hyaluronic Acid Blend: binds and attracts moisture to our skin, helping our cells ""plump"" and reduce the appearance of fine lines and wrinkles. The three weights penetrate the skin at different levels of depth to target multiple concerns.

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.
