Glycolic acid - 7%
An extremely effective exfoliator that promotes radiant skin, blemish reduction, and is known to clear up dry patches and/or hyperpigmentation. We formulated this transformative serum with a potent but non-irritating 7% for noticeable next day results.
Gluconolactone - 5%
An exfoliating acid that happens to be an excellent hydrator. Did we also mention it's super gentle?
Succinic Acid - 2%
This buzzy ingredient is relatively new in skincare, known for its acne-fighting abilities. It inhibits bacterial growth that leads to blemishes, while calming and relieving skin discomfort.

Texture
A waterweight, transparent fluid that absorbs quickly into the skin.
When
Twice a week in the morning or evening, after cleansing and before moisturizing.
