The formulation
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.
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.
A pigment-pathway inhibitor that fades stubborn discolouration including melasma and post-inflammatory marks, often paired with niacinamide for tone correction.
A humectant that binds water in the upper skin layers for immediate plumping and hydration. Multi-weight forms reach different depths. Apply to damp skin and seal with moisturiser, especially in dry climates.
