Skincare, simply explained
Adenosine is a skincare ingredient used for a smoother-looking complexion. It is especially worth knowing if you are choosing a cream or eye product for visible fine lines.
Can help smooth the appearance of fine lines with regular use, including lines around the eyes.
Helps care for the skin’s surface as part of a comfortable cream or serum.
Adenosine is a compound that occurs naturally in living cells, including those in the human body. In skincare, it is used as an individual ingredient to condition skin and care for the appearance of fine lines. The name on the ingredient list is simply Adenosine.
You’ll find it in face creams, serums and eye products, including formulas made for crow’s feet. It can sit alongside ingredients such as glycerin and hyaluronic acid: those ingredients help hold moisture, while adenosine adds a focus on visible lines. A cream or serum can therefore bring hydration and line care together in one step.
