Sérum Acide salicylique + Niacinamide

Matches all three key actives - niacinamide, salicylic acid, and ascorbyl glucoside - though salicylic acid appears lower in the list suggesting a lower concentration, and it contains alcohol denat plus synthetic dyes/fragrance the source doesn't have.

Shares the two hero actives niacinamide and salicylic acid, but lacks the ascorbyl glucoside brightening antioxidant and adds a bunch of extra actives (arbutin, willow bark, centella) that change the formula's character.

Only shares salicylic acid; it's missing both niacinamide and ascorbyl glucoside, which are core to the source's brightening/soothing benefits.

Only overlaps on niacinamide; it has no salicylic acid for exfoliation and no ascorbyl glucoside, plus it's a dewy glow serum with different actives (hyaluronic acid, watermelon extract) entirely.

Shares salicylic acid (likely as a minor acid in an AHA blend) and citric acid, but is missing niacinamide and ascorbyl glucoside, and is fundamentally a glycolic/lactic acid exfoliating serum, not a niacinamide-salicylic acid formula.
