These two serums take different paths to a similar destination. Both formulas include solid hydrating ingredients, and the overall scores reflect that — the gap here is genuinely slim.
Hydration Efficacy is another area of separation. LANEIGE Water Sleeping Mask EX scores 9.8 here versus 5.8 for INNBEAUTY PROJECT Pro C Serum Brightening Solution with 15% Vitamin C + Ferulic Acid. That difference comes down to how each formula is built — the ingredient list tells the story.
INNBEAUTY PROJECT Pro C Serum Brightening Solution with 15% Vitamin C + Ferulic Acid brings Tetrahexyldecyl Ascorbate, Niacinamide, and Ascorbic Acid as actives, while lANEIGE Water Sleeping Mask EX relies on Niacinamide, Allantoin, and Caffeine. Both approaches have merit, but the positioning and supporting ingredients make the difference.
At premium pricing with a score of 8.4, INNBEAUTY PROJECT Pro C Serum Brightening Solution with 15% Vitamin C + Ferulic Acid is a decent pick. LANEIGE Water Sleeping Mask EX sits at the mid-range level with a 8.4 score — the extra cost doesn't translate to better scores here.
