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.
Formulation Safety is another area of separation. Tirtir Ceramic Milk Ampoule scores 8.5 here versus 8.0 for SK-II GenOptics Infinitaura Brightening Serum with Niacinamide, 30ml. That difference comes down to how each formula is built — the ingredient list tells the story.

Both approaches have merit, but the positioning and supporting ingredients make the difference.
