Functions and Efficacy
• Whitening and Spot Removal: SAP can release active vitamin C through decomposing enzymes in the skin, thereby inhibiting the activity of tyrosinase, reducing melanin synthesis, and also reducing already formed melanin, achieving the effect of lightening spots and brightening skin tone.
• Antioxidation: As an effective water-soluble antioxidant, SAP can eliminate free radicals, protect cells from damage caused by free radicals, prevent skin aging, and delay the occurrence of wrinkles and sagging.
• Promoting Collagen Synthesis: It can promote collagen production, help maintain skin elasticity and firmness, and keep the skin looking young.
• Moisturizing Effect: SAP has certain moisturizing properties, which can help the skin retain moisture, improve dry skin conditions, and make the skin more hydrated.
• Anti-inflammatory and Soothing: SAP also has anti-inflammatory properties, which can soothe sensitive skin, relieve discomfort such as skin redness and itching, and have a certain improving effect on some inflammation-related skin problems.
• Usage Concentration
• Daily Skincare Products: The general usage concentration is 0.2%-2%. Within this concentration range, it can provide basic antioxidant and moisturizing effects, helping to maintain healthy skin condition.
• Sunscreen Products: The usual addition amount is 0.2%-1%, which can assist in sun protection, reduce skin damage from ultraviolet rays, and enhance the antioxidant performance of sunscreen products.
• Whitening Products: When the concentration is greater than 3%, the whitening effect is more significant, effectively inhibiting melanin production, lightening spots, and brightening skin tone.
• Combination Recommendations
• Combined with Vitamin E: SAP can be combined with oil-soluble vitamin E acetate to form an ideal antioxidant system, which can more comprehensively resist daily environmental stress on the skin and exert synergistic antioxidant effects.
• Combined with Other Moisturizing Ingredients: Such as hyaluronic acid, glycerin, etc., which can enhance the skin's moisturizing effect and make the skin more hydrated and smooth.
• Combined with Other Whitening Ingredients: Such as niacinamide, which can inhibit melanin production and transport from different pathways and synergistically enhance the whitening effect.
