Ingredient stack
Each ingredient is listed in descending concentration. Above the 1% line the order is regulated — below it, brands can list in any order.
Ingredients above the dashed gold line are dosed above 1% (the regulatory threshold) — these are what the formulation is really built on. Percentages are positional estimates from INCI order unless a brand discloses them.
The smallest AHA, so it penetrates efficiently to loosen dead surface cells, smoothing texture and boosting radiance. Increases sun sensitivity — daily SPF is essential.
An oil-soluble BHA that exfoliates inside the pore, dissolving the sebum and dead-cell plugs behind blackheads and congestion. Anti-inflammatory and especially suited to oily, acne-prone skin.
Vitamin B3. Regulates sebum, strengthens the barrier by boosting ceramide synthesis, evens tone by limiting pigment transfer, and calms inflammation. Well-tolerated at 2–10%; one of the most versatile, evidence-backed actives.
