Suitable for

All skin types including dry, mature, sensitive, blemish-prone, combination, and normal skin.

Why we stand behind it

Normally, vitamin C degrades and oxidizes when coming into contact with air or water. So GOOP created this two-part system to ensure that it remains stable and effective until the moment you use it. A combination of L-ascorbic acid (purest form of vitamin C) and hyaluronic acid team up to brighten skin and improve firmness, tone, and hydration.

Immediately, after one use*:
- 100% of women showed a dramatic improvement in skin hydration.

After eight weeks of twice-daily use*:
- 91% of women showed a significant improvement in skin firmness.
- 82% said the product visibly improved skin discoloration and reduced dark spots.

** Based on a twelve-week third-party clinical study of twenty-three women ages 27-50.

Key ingredients

L-ascorbic acid (purest form of vitamin C): Brightens skin
Three different molecular sizes of hyaluronic acid: Penetrates different layers of skin for maximum effectiveness.
Australian Kakadu plum: Provides antioxidant superfruit benefits.

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:


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.


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.


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.

Potent L-ascorbic acid has been bottled on its own as a powder to be mixed with a unique hyaluronic acid serum when you′re ready to use it for the first time.
For maximum potency, use the serum within three months of mixing together. Though the serum remains active for longer than that, it′s bottled as a three-month supply, so you′re assured the freshest, most powerful dose of vitamin C for your skin.

First use:

Unscrew the tip of the serum activator and squeeze all the contents into the bottle containing the pure Vitamin C powder. Screw the cap on the bottle and shake well until the powder fully dissolves. Replace the cap with the dropper; it′s now ready to use.

Smooth a few drops between your palms, then apply to clean, dry face and neck twice daily. Use during the day to help protect your skin from free radicals and UV rays, and in the evening to help undo oxidative damage from the day.
Use SPF daily to maintain results and help protect skin from future damage.
For best results, use within three months of activating the serum


Before your first use, mix the super potent 20% L-ascorbic acid powder with the hyaluronic acid serum.
