• Neutralizes free radicals and UV-induced skin damage
• Enhances stability of L-Ascorbic Acid and Vitamin E
• Ideal for anti-aging, brightening, and photo-protection formulas
• Can improve skin tone and reduce fine lines
• Compatible with most actives in emulsions and serums

Ferulic Acid is a naturally occurring phenolic antioxidant derived from rice bran, oats, and certain fruits and vegetables. It is most well-known in cosmetic science for its ability to stabilize and boost the performance of Vitamin C (Ascorbic Acid) and Vitamin E (Tocopherol) — making it a gold-standard ingredient in advanced antioxidant serums. In addition to neutralizing free radicals, Ferulic Acid can improve the appearance of uneven skin tone, reduce the look of fine lines, and prevent oxidative skin damage. It is particularly popular in photoprotective and anti-aging skincare formulas.

🌞 Combine Ferulic Acid with 15% Vitamin C (L-Ascorbic Acid) and 1% Vitamin E (Tocopherol) for a powerful antioxidant serum that mimics luxury anti-aging products — but DIY at a fraction of the price. Store in amber or airless packaging to prevent degradation.

✔️ Suitable for all skin types including mature, sensitive, oily, and combination skin

⚠️ Best used with pH monitoring and proper solubilization

1. Advanced Antioxidant Serum

Create a brightening serum with 15% Vitamin C, 1% Vitamin E, and 0.5% Ferulic Acid. Dissolve Ferulic in a propanediol/glycerin mixture before combining with the water phase. Ideal for daytime use under sunscreen.

2. Anti-Aging Day Cream

Add Ferulic Acid into a pH-balanced emulsion containing peptides, niacinamide, and green tea extract. It boosts UV protection when worn under sunscreen.

3. Brightening Spot Treatment Gel

Formulate a lightweight gel with alpha arbutin, licorice root, and Ferulic Acid for targeted hyperpigmentation and antioxidant support.

4. Night Recovery Mask

Infuse a creamy overnight mask with Ferulic Acid, bakuchiol, and panthenol. It helps reduce signs of oxidative damage while the skin repairs overnight.

5. Eye Cream for Fine Lines

Use Ferulic at 0.3% with caffeine, panthenol, and peptides in an emollient base for an antioxidant-rich under-eye cream.

Q1: Can Ferulic Acid be used in water-based serums?

A1: Not directly — Ferulic Acid is poorly water-soluble. It requires solubilizers like propylene glycol, propanediol, or ethanol to properly dissolve and stay stable in formulas.

Q2: Is Ferulic Acid safe for daily use?

A2: Yes! When used at 0.3–1% concentration in well-formulated products, it is safe for daily use, especially when combined with other antioxidants like Vitamin C and E.

Q3: Does Ferulic Acid need a preservative?

A3: Ferulic Acid itself is not a preservative. Your formula still requires a full-spectrum preservative system to protect against microbial growth.

Q4: Can I mix Ferulic Acid with Vitamin C at home?

A4: Yes, but with caution. DIY Vitamin C + Ferulic Acid serums require accurate pH control (around 3.2–3.5), proper solubilizers, and opaque/airless packaging to remain stable and effective.

Q5: Will Ferulic Acid oxidize or change color over time?

A5: Yes, especially in the presence of air, light, or high temperature. Store in amber bottles or airless pumps in a cool, dark place to maximize shelf life.
