Decoding Ferulic vs Phloretin: Choosing the Right Antioxidant

Antioxidants are chemicals that can defend skin cells against damage from free radicals. Free radicals are unstable molecules constantly produced in our bodies, which can attack our cells, leading to skin aging, pigmentation, fine lines, and sagging. Therefore, antioxidants play a crucial role in skincare.

Ferulic acid and phloretin are common antioxidants. Ferulic acid, extracted from chuanxiong and bran, has effects like improving pigmentation, antioxidation, and sun protection, helping the skin maintain youthfulness and radiance. It's widely used in skincare products for firming, anti-aging, and it's safe with high metabolism. Phloretin, a natural antioxidant mainly found in plants like apples, grapes, and strawberries, effectively combats free radical damage, improving issues like pigmentation, uneven skin tone, fine lines, and sagging. So, which antioxidant should we choose specifically?

Understanding Ferulic Acid:

Ferulic acid is mainly derived from plants or synthesized chemically. Extracted ferulic acid from plants has minimal toxic side effects on humans and can be directly applied in pharmaceutical and food industries, making it a major source for medical ferulic acid. Its widespread presence in nature gives it significant pharmacological activity and stable chemical properties. Due to its antioxidant, anti-inflammatory, anticoagulant, detoxifying, liver-protective, and immune-regulating effects, researchers extensively study ferulic acid and its derivatives for various applications like cosmetics and food preservatives.

Ferulic acid esters exhibit excellent antioxidant properties in cosmetic formulations, providing good antioxidant and skin whitening effects. Studies by Liu Yanhong, Yang Zijia, and others on the antioxidant action of ferulic acid esters revealed their ability to effectively eliminate oxygen free radicals, with a clearance rate exceeding 12%. Furthermore, the clearance effects on DPPH radicals and superoxide anions showed significant results.

Exploring Phloretin:

Recent studies have found multiple pharmacological effects of phloretin, including antioxidant, immunosuppressive, blood sugar reduction, and roles in cell proliferation and apoptosis. Additionally, it offers beauty benefits like reducing dark spots, smoothing skin texture, and delaying aging. Phloretin, a natural antioxidant found in apples, pears, and other plants, not only neutralizes free radicals generated by UV, infrared radiation (IRA), and ozone pollution but also enhances the action of other antioxidants, improving the appearance of uneven skin tone and minimizing sun damage.

The skin possesses a natural antioxidant system to protect against damage from internal and external factors. However, the levels of endogenous antioxidants decrease with age or changes in external environments. Research indicates that phloretin can effectively protect the skin from damage caused by free radicals or UV radiation from cell metabolism. Hence, phloretin is widely used in cosmetics to eliminate skin wrinkles, pigmentation, and prevent UV-induced skin damage.

Ferulic vs Phloretin

(1)Antioxidant Capacity and Stability:

Both compounds exhibit potent antioxidant properties, making them valuable additions to skincare formulations. Ferulic acid, extracted from plants like rice bran and oats, is renowned for its ability to neutralize free radicals and protect the skin from oxidative stress.

However, a notable difference lies in their stability. Phloretin's chemical structure contains a phenyl ring and a hydroxyl group, imparting a certain level of stability. It remains relatively stable under acidic and alkaline conditions but can degrade under high temperature and light. Ferulic acid, an organic acid, is less stable than phloretin and prone to degradation under high temperature and light. Nonetheless, ferulic acid can be used in combination with other antioxidants like vitamin C and E to form more stable antioxidant complexes. Ferulic acid exhibits greater stability when incorporated into skincare products, maintaining its antioxidant efficacy over time. In contrast, phloretin may demonstrate reduced stability, requiring special formulation techniques to ensure its longevity and effectiveness.

(2)Compatibility with Other Skincare Ingredients:

The compatibility of ferulic acid and phloretin with other skincare ingredients slightly differs. Ferulic acid is known to enhance the stability and efficacy of other antioxidants such as vitamin C and E when used in combination with them.
