Ferulic Acid CAS 1135-24-6

1. Powerful Antioxidant, Delaying Skin Aging
Mechanism of Action: The phenolic hydroxyl structure of ferulic acid effectively scavenge free radicals (such as superoxide anions and hydroxyl radicals), inhibit lipid peroxidation, and reduce free radical damage to skin cell DNA and collagen. Simultaneously, ferulic acid activates the skin's own antioxidant enzymes (such as SOD and glutathione peroxidase), enhancing the skin's natural antioxidant capacity.
Actual Effects: Delays the formation of wrinkles, improves skin laxity, brightens dull skin tone, and reduces "oxidative aging" caused by lack of sleep and UV exposure. Suitable for use in anti-aging serums, creams, lotions, and other products.
Synergistic Advantages: When combined with ingredients such as Vitamin C, Vitamin E, and niacinamide, the antioxidant effect can be synergistically enhanced (ferulic acid protects Vitamin C from oxidation, prolonging its activity), making it a "synergist" in anti-aging formulas.
2. Whitening and Fading Dark Spots, Improving Pigmentation
Mechanism of Action: Reduces melanin production by inhibiting the activity of tyrosinase (a key enzyme in melanin synthesis); simultaneously inhibits the transport of melanocytes to the stratum corneum, accelerating the metabolic shedding of melanocyte-containing cells in the stratum corneum, and also fades existing dark spots and acne scars.
Actual Effects: Brightens skin tone, improves uneven skin tone, fades sun spots, freckles, acne scars, and post-inflammatory hyperpigmentation (such as dark marks left by acne). Suitable for use with whitening serums, dark spot masks, brightening toners, etc.
Advantages and Features: Gentle whitening effect, does not irritate the skin barrier, and is safer than potent whitening ingredients such as hydroquinone, making it suitable for whitening sensitive skin.
3. Anti-inflammatory and Soothing, Repairing the Skin Barrier
Mechanism of Action: Inhibits the release of inflammatory factors (such as TNF-α and IL-6), reducing skin inflammation; simultaneously inhibits the activity of cyclooxygenase (COX) and lipoxygenase (LOX), relieving skin redness and burning sensation.
Actual Effects: Soothes sensitive and reddened skin (such as rosacea, seasonal sensitivity), alleviates skin inflammation after UV exposure (sunburn redness), repairs damaged skin barrier, and is compatible with skincare products specifically for sensitive skin, after-sun repair products, and anti-inflammatory serums.
Suitable Scenarios: Can be added to gentle cleansers and soothing lotions to reduce product irritation and improve user comfort.
4. Sun Protection, Enhancing Sunscreen Efficacy
Mechanism of Action: Possesses a certain UV absorption capacity (primarily absorbing UVA and UVB bands, absorption peak approximately 290-330nm), directly blocking some UV damage to the skin; simultaneously inhibits UV-induced skin inflammation and oxidative stress, reducing photoaging damage.
Actual Effects: As an "auxiliary ingredient" in sunscreens, adding it to sunscreens can enhance overall sun protection (moderately increasing SPF and PA values), while also alleviating the irritation of sunscreen products and reducing skin dryness and redness caused by UV rays.
Combination Logic: When combined with physical sunscreens (such as zinc oxide and titanium dioxide) or chemical sunscreens (such as ethylhexyl methoxycinnamate), it can compensate for the limited wavelength range of a single sunscreen, enhancing its broad-spectrum protection.
5. Moisturizing and Repairing, Improving Dry Skin
Mechanism of Action: Promotes the synthesis of intercellular lipids in the stratum corneum (such as ceramides and cholesterol), enhancing the stratum corneum's water-locking ability; it also improves the moisture content of the stratum corneum, increasing skin hydration and elasticity.
Actual Effects: Relieves dry, flaky skin, improves rough skin texture, leaving skin smoother and more delicate. Suitable for use with moisturizing face creams, hand creams, body lotions, etc., especially suitable for dry skin and use in autumn and winter.
