What Is Cistus Incanus Extract?
Cistus incanus extract is derived from the aerial parts of Cistus incanus, a Mediterranean shrub traditionally used in folk medicine for skin conditions. The extract is rich in polyphenolic compounds—naturally occurring plant chemicals with antioxidant properties—which form the basis of its skincare function.
In cosmetic formulations, this ingredient functions as a skin protectant, working to defend the skin against environmental stressors and oxidative damage that can contribute to premature ageing and other skin concerns.
How It Works
Cistus incanus extract works primarily through its high concentration of flavonoids and other polyphenolic compounds. These molecules function as chain-breaking antioxidants, meaning they interrupt the cascade of free radical damage at a cellular level. When skin is exposed to UV radiation or pollution, unstable molecules called free radicals form and damage skin cells. The polyphenols in this extract donate electrons to stabilise these free radicals, preventing them from harming lipids, proteins, and DNA within the skin.
The extract has also demonstrated a dose-dependent free-radical scavenging capacity in research, suggesting that its protective effect increases with concentration in a formulation.
Clinical Evidence & References
Laboratory studies have shown that Cistus incanus extract exhibits measurable antioxidant activity and protective effects against DNA cleavage—a marker of cellular damage. The extract demonstrated free-radical scavenging capacity and the ability to inhibit lipid peroxidation, a process that damages cell membranes. These findings suggest potential benefit for skin protection against oxidative stress.
However, most evidence to date comes from in vitro (laboratory) studies rather than clinical trials in human subjects. Whilst the results are promising, further human research would help establish the practical efficacy and optimal concentrations needed for meaningful skin benefits in real-world use.
How to Use
Cistus incanus extract is typically used as part of a broader skincare routine rather than as a standalone treatment. It is commonly found in serums, moisturisers, and sun protection products where it works alongside other protective ingredients. For best results, layer it with a broad-spectrum sunscreen and other antioxidants such as vitamin C or vitamin E, which may offer complementary protection.
