Formulation Tips for Vitamin-Based Ingredients

1. Adjust the Right Concentration
The optimal concentration of each vitamin varies, and selecting the right concentration ensures the ingredient works effectively without causing irritation.
Vitamin C: Typically, a concentration of 5% to 20% works well. Higher concentrations may cause irritation, especially for sensitive skin, while lower concentrations mayy not provide visible effects.
Vitamin E: A concentration of 0.5% to 2% is commonly used to provide the best results without leaving a greasy feeling.
Vitamin A: Retinol is usually used in concentrations between 0.1% to 1%, with lower concentrations recommended for sensitive skin, gradually increasing the dose over time.

2. Avoid Combining with Certain Ingredients
Some vitamins may interact negatively with other ingredients, reducing their effectiveness or causing irritation. It’s important to avoid certain combinations in formulations:
Vitamin C and Vitamin A: Ascorbic acid (Vitamin C) and retinol (Vitamin A) should not be combined in the same formulation. They have different pH requirements and can destabilize each other, reducing their efficacy.
Vitamin C and Certain Metal Ions: Metals like iron and copper may catalyze the oxidation of Vitamin C, reducing its antioxidant benefits. Avoid including these metals in formulas with Vitamin C.

3. Control pH Levels
Vitamin C and other water-soluble vitamins are highly sensitive to pH levels, and ensuring the right pH helps maintain their stability and absorption.
Vitamin C: Ascorbic acid performs best at a pH between 3.5 and 4.5. If the pH is too high, Vitamin C will lose its activity and effectiveness.
Vitamin A: Retinol performs best in a slightly neutral or mildly alkaline environment. A highly acidic pH can cause it to degrade.

4. Use in Combination with Other Skincare Ingredients
Vitamin-based ingredients often work best when combined with other skincare ingredients to enhance their effects. For example:
Vitamin C and Hyaluronic Acid: Hyaluronic acid hydrates the skin, which helps Vitamin C penetrate deeper into the skin, boosting its antioxidant effects.
Vitamin A and Peptides: Peptides support skin repair and complement the anti-aging effects of Vitamin A, boosting its efficacy in stimulating collagen production.

Some Common Vitamins And Their Stability Issues

1. Vitamin C (Ascorbic Acid)
Oxidation: It is easily oxidized when exposed to air, which can turn the product yellow or brown, indicating degradation.
Photosensitivity: Degrades quickly under UV light, so it should ideally be stored away from light.
pH Dependence: It is most stable in an acidic environment around pH 3.5, but this low pH can irritate sensitive skin

2. Vitamin A (Retinol and its Derivatives)
Photosensitivity: Retinol degrades under UV light, so it is typically recommended for nighttime use and stored in opaque packaging.
Heat Sensitivity: High temperatures can accelerate its breakdown, making temperature control important during manufacturing and storage.
pH Sensitivity: It is unstable in both highly acidic and highly alkaline conditions, so a neutral environment is preferred.

3. Vitamin E (Tocopherol)
Oxidation: While Vitamin E is an antioxidant, it can still oxidize under high temperatures or prolonged exposure to air.
Formulation Compatibility: It is more stable in oil-based systems and is usually added to the oil phase, but mixing it with certain unstable ingredients may affect overall stability.

4. Niacinamide
Niacinamide is most stable in a pH range of 4-7. In highly acidic (pH<4) or highly alkaline (pH>7) environments, it may hydrolyze into nicotinic acid, which can cause skin irritation or discomfort. Thus, keeping the pH within the 4-7 range is ideal to maintain niacinamide’s effectiveness and minimize irritation.
Niacinamide can be unstable when combined with pure Vitamin C (ascorbic acid) in acidic conditions, as it may convert to nicotinic acid. However, using stabilized Vitamin C derivatives (such as sodium ascorbyl phosphate) can improve compatibility in formulations.
When mixed with acids (such as alpha-hydroxy acids or beta-hydroxy acids), the pH can become too low for niacinamide’s stability, again risking conversion to nicotinic acid. Formulation with acids requires special attention to pH management.
