Where Anua Niacinamide 10% + TXA 4% Serum really shines is hydration efficacy, scoring 8.4 compared to StriVectin Super-C Retinol Brighten & Correct Vitamin C Serum's 5.8. With Glycerin, Butylene Glycol, and Sodium Hyaluronate in its top ingredients, Anua Niacinamide 10% + TXA 4% Serum delivers stronger moisture-binding capability.
Active Ingredient Strength is another area of separation. StriVectin Super-C Retinol Brighten & Correct Vitamin C Serum scores 9.7 here versus 8.5 for Anua Niacinamide 10% + TXA 4% Serum. That difference comes down to how each formula is built — the ingredient list tells the story.
Anua Niacinamide 10% + TXA 4% Serum brings Niacinamide, Tranexamic Acid, and Alpha-Arbutin as actives, while striVectin Super-C Retinol Brighten & Correct Vitamin C Serum relies on Sodium Ascorbyl Phosphate, Ascorbyl Glucoside, and Ascorbic Acid. Both approaches have merit, but the positioning and supporting ingredients make the difference.
At budget pricing with a score of 8.8, Anua Niacinamide 10% + TXA 4% Serum delivers strong value. StriVectin Super-C Retinol Brighten & Correct Vitamin C Serum sits at the premium level with a 8.4 score — the extra cost doesn't translate to better scores here.
