Why these two are neck and neck

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. Medicube Deep Vita A Retinol Serum scores 9.8 here versus 7.4 for SEPHORA Beauty insider. That difference comes down to how each formula is built — the ingredient list tells the story.
