Vitamin C Serum for Sensitive Skin (Brightening and Anti-Aging)

For a Vitamin C serum suitable for sensitive skin that targets brightening and wrinkles, while I cannot provide specific percentage formulations, I can recommend key ingredients and considerations.

Vitamin C is a powerful antioxidant known for its ability to brighten skin tone, fade dark spots, stimulate collagen production to reduce wrinkles, and protect against environmental damage.

For sensitive skin, it's crucial to choose stable and less irritating forms of Vitamin C compared to L-Ascorbic Acid. Recommended forms include:

• Sodium Ascorbyl Phosphate (SAP): A water-soluble, highly stable form that is gentle and effective for brightening.
• Magnesium Ascorbyl Phosphate (MAP): Another stable, water-soluble form known for its mildness and effectiveness in brightening and promoting collagen synthesis.
• Ascorbyl Glucoside (AA-2G): A stable, water-soluble derivative that converts to L-Ascorbic Acid upon absorption, offering sustained release and reduced irritation.
• Ascorbyl Tetraisopalmitate (Perfect-C™): An oil-soluble form with excellent stability and skin penetration, known for its potent brightening, anti-aging, and antioxidant properties with very low irritation potential.

To enhance the serum's benefits and soothe sensitive skin, consider incorporating these complementary ingredients:

• Niacinamide (Vitamin B3): Helps strengthen the skin barrier, reduce redness and inflammation, and improve overall skin tone and texture. Look for high-purity versions like Safe-B3™.
• Hyaluronic Acid: Provides intense hydration, plumping the skin and reducing the appearance of fine lines without causing irritation.
• Allantoin: A soothing ingredient that helps calm the skin and promote healing.
• Vitamin E (Tocopheryl Acetate): A classic antioxidant that works synergistically with Vitamin C to provide enhanced protection against free radicals.
• Ferulic Acid (Pure-Ferulic Acid™): Another potent antioxidant that boosts the stability and effectiveness of Vitamin C and Vitamin E.

When formulating or choosing a product for sensitive skin, always start with lower concentrations of active ingredients and patch test. Ensure the overall formulation avoids common irritants like high concentrations of alcohol or fragrance.

By combining stable forms of Vitamin C with soothing and barrier-supporting ingredients, you can create a potent yet gentle serum for brightening and anti-aging benefits on sensitive skin.
