This serum gently exfoliates your skin giving it a more glowy and even complexion. It also hydrates, locks in moisture, and soothes your skin, and ingredients such as 2% oat milk and four different seed butters helps plump your skin and supports a more durable skin barrier. Suitable for all skin types, even for those with dry or sensitive skin.

You may experience some stickiness upon initial application, but that's normal! It will disappear after the serum dries, but you can layer with moisturizer.
