What they are
Timed-release antioxidants are antioxidant ingredients engineered to release gradually over time, rather than delivering their effect all at once. This controlled delivery helps maintain antioxidant activity for longer and improves overall tolerability.
How they work in skincare
By releasing slowly, timed-release antioxidants provide sustained protection against free radical damage throughout the day or night. This improves ingredient stability, reduces the risk of irritation and ensures ongoing defence against environmental stressors such as UV exposure and pollution.
One of the most popular examples of time-released antioxidants is encapsulated vitamin C. The active ingredient is protected within a delivery system that allows it to be released gradually into the skin. The slow release system helps preserve potency while reducing the stinging or sensitivity some people experience with traditional vitamin C formulas. Other examples include time-released vitamin E and coenzyme Q10, offering longer-lasting antioxidant support without overwhelming the skin.
Timed-release systems are especially helpful for sensitive skin and for those using active ingredients such as retinoids and exfoliating acids. They are also well-suited to people who prefer a simple, low-maintenance routine, offering consistent antioxidant protection without the need for frequent reapplication or layering multiple products.
