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.
