BioChem™️ 10% Ascorbic Acid

Ascorbic acid is the pure, biologically active form of Vitamin C.
It’s a water-soluble antioxidant naturally found in fruits and vegetables (especially citrus, berries, and peppers).
In skincare, it’s known for brightening, collagen stimulation, and protection against oxidative damage.

Benefits

1. Powerful Antioxidant

   • Neutralizes free radicals caused by UV light and pollution.

2. Boosts Collagen Production

   • Supports synthesis of collagen and elastin, improving skin firmness.

3. Brightens Skin

   • Reduces hyperpigmentation, dark spots, and post-acne marks.

4. Evens Skin Tone

   • Helps with dullness and overall radiance.

5. Enhances Sunscreen Effectiveness

   • Works synergistically with SPF to reduce UV-induced skin damage.

Uses

• Typical concentration: 5–20% in serums or creams.

  • 10–15% is common for daily use.

• Best applied:

  • In the morning after cleansing and before sunscreen.

• Often combined with:

  • Vitamin E and ferulic acid to improve stability and effectiveness.

FDA Cautions & Safety

• FDA Status:

  • Ascorbic acid in cosmetics is not regulated as a drug unless therapeutic claims are made.

  • It is Generally Recognized as Safe (GRAS) for oral consumption and considered safe topically in cosmetic concentrations.

• Stability Concerns:

  • Pure ascorbic acid is highly unstable—it oxidizes quickly when exposed to air, light, or heat, turning yellow/brown (which means it’s losing potency).

  • FDA notes that ingredient degradation can reduce product effectiveness.

• Possible Side Effects:

  • Mild irritation, redness, or tingling—especially with higher concentrations or sensitive skin.

• Cautions:

  • Patch test first.

  • Avoid mixing with certain ingredients (like high-concentration niacinamide) unless formulation is designed for it.
