Ingredient research in this formula

These are ingredient-level research links, not evidence that this exact product has been clinically tested.

  • ChamomileGood evidenceFull dossier

    The classic "tea-bag-on-puffy-eyes" botanical. Calms angry skin via well-studied anti-inflammatory pathways, gently. Good for reactive or rosacea-prone complexions.

    Good for: Anti-inflammatory, Antioxidant

  • Citric AcidGood evidenceFull dossier

    A fruit-derived AHA that exfoliates and antioxidizes. It shares the same basic mechanism as glycolic and lactic acid but is weaker gram-for-gram; in practice you'll see it doing dual duty (a little exfoliation plus pH stabilisation) in multi-acid toners and serums. When it appears low on an ingredient list, it's adjusting pH; higher up, it's contributing real exfoliation.

    Good for: Exfoliating, Antioxidant

New to this? Patch test on your inner arm for 24 to 48 hours before applying to your face. If you have sensitive skin or rosacea, start 2 to 3 times per week and build up slowly.
