Composition and Sources Phloretin is a natural dihydrochalcone flavonoid compound, primarily found in the root bark, pericarp, and leaves of Rosaceae plants such as apples and pears, with particularly high content in apple peels. Its chemical structure exhibits strong antioxidant activity, making it a key functional component in plant secondary metabolites. It is often obtained as a high-purity product through plant extraction processes and is a typical Natural Plant Extract Rich in Phloretin. Core Benefits Potent antioxidant activity
It can scavenge free radicals in the body (such as superoxide anions and hydroxyl radicals), inhibit lipid peroxidation, and protect cells from oxidative damage. Its antioxidant capacity is superior to some common flavonoids (e.g., quercetin).
Skin whitening and protection
Inhibits tyrosinase activity to reduce melanin synthesis, while blocking the transport of melanin in the epidermal layer, thereby lightening spots and brightening skin tone. Additionally, it can absorb ultraviolet rays (mainly UVB) to help protect the skin from photodamage and delay skin aging—making it highly valuable for phloretin for skin.
Metabolic regulatory effects
Promotes the breakdown of fat cells and inhibits fat synthesis, potentially aiding in improving obesity and metabolic syndrome. It can also enhance insulin sensitivity and promote glucose transport, with potential benefits for blood sugar regulation (currently mostly cell and animal studies, with further human research needed).
Anti-inflammatory and cardiovascular protection
Inhibits the expression of inflammatory factors (e.g., IL-6, NF-κB) to reduce chronic inflammatory responses. It also improves vascular endothelial function and inhibits platelet aggregation, providing certain protective effects on cardiovascular health.
Application Fields Cosmetics industry
Added to skincare products (such as serums and creams) as a whitening and antioxidant ingredient, used to improve pigmentation and anti-aging, especially suitable for dull and spotted skin—this is a major application of phloretin for skin.
Healthcare products and functional foods
Formulated into capsules, tablets, and other dosage forms as antioxidant and metabolism-regulating supplements. Derived from natural plant sources, it serves as a Plant Based Phloretin Supplement Source, suitable for people concerned with skin health, weight management, and cardiovascular care.
Pharmaceutical research and development
Based on its anti-inflammatory and metabolic regulatory properties, it is being studied for potential drug development to assist in improving obesity, diabetes, and cardiovascular diseases (currently in laboratory research stages).
