Vitamin C + E + Ferulic Cream

In brief

Vitamin C + E + Ferulic cream is considered the gold standard antioxidant combination in topical skincare.
👉 It provides superior protection against photoaging and pollution.
👉 The combination is more effective and more stable than vitamin C alone.

🟢 What it does (main evidence)

• Provides enhanced antioxidant protection.
• Supports collagen synthesis.
• Improves skin brightness and firmness.
• Boosts the effectiveness of sunscreen (complementary).

🟡 What is unclear

• Tolerance varies by skin type.
• Limited impact on deep wrinkles.

🔴 What it does NOT do

• Does not replace sunscreen.
• Does not work overnight.
• Is not essential for minimal routines.

Concentrations & forms

• Vitamin C (L-ascorbic acid): 10–20%.
• Vitamin E: 0.5–1%.
• Ferulic acid: 0.3–0.5%.
• Optimal pH: ≈ 3–3.5.

💣 Practical upper limit

Note: exceeding $≈ 15–20% vitamin C + 1% vitamin E + 0.5% ferulic acid rarely improves results
but increases irritation and instability.

Safety

• Introduce gradually on sensitive skin.
• Always pair with sunscreen.

Practical usage tips

• Apply in the morning.
• Store away from light and heat.
• Discard if the product darkens significantly.
