Vitamin C (ascorbic acid, magnesium ascorbyl phosphate, sodium ascorbyl phosphate)
Category: Active ingredient, Skin lightening agent, Antioxidant
Brief description: Vitamin C is an antioxidant that provides various skin benefits, including brightening, collagen synthesis promotion, and protection against environmental stressors.
Benefits: Brightening, collagen synthesis promotion, antioxidant protection.
Skin type suitability/concerns: Suitable for all skin types; may cause irritation in sensitive or acne-prone skin at higher concentrations.
Target audience: People looking to address hyperpigmentation, signs of aging, or environmental damage.
Chemical composition: Ascorbic acid and its derivatives (magnesium ascorbyl phosphate, sodium ascorbyl phosphate) are organic compounds with antioxidant properties.
Physical aspect: White or pale yellow crystalline powders, depending on the specific form of vitamin C.
Compatibility: Ascorbic acid is sensitive to light, heat, and air; derivatives are more stable but still require proper formulation to maintain stability and efficacy.
Concentration: Ascorbic acid is typically used at concentrations of 5-20%; derivatives are used at concentrations of 1-10%.
Side effects/adverse reactions: Some may experience skin irritation, especially with higher concentrations of ascorbic acid. It's also known to cause a temporary "flushing" effect on the skin.
Regulatory status: Generally recognized as safe, but specific regulatory status may vary depending on the country or region.
Sustainability/ethical considerations: Can be synthesized or derived from natural sources; no significant sustainability or ethical concerns.
