Does Paula's Choice 10% Azelaic Acid Booster contain parabens, sulfates or fragrance?

A straight yes or no for the ingredient groups people most often want to avoid, checked against this product's published formulation.

  • Free from parabens

    Preservatives; the longer-chain ones (propyl, butyl) carry the endocrine questions.

  • Free from sulfates (sls / sles)

    Strong cleansing agents that can strip a compromised barrier.

  • Contains silicones

    Found: cyclopentasiloxane, cyclohexasiloxane. Slip and occlusion; cyclic silicones (D4/D5/D6) are the environmentally restricted ones.

  • Free from fragrance / parfum

    Undisclosed fragrance blends are the most common trigger for sensitised skin.

  • Free from essential oils

    Naturally derived, but among the most frequently reported contact allergens.

  • Contains drying alcohol

    Found: phenoxyethanol. Fine in small amounts for texture; high up the list it can dehydrate.

  • Free from formaldehyde releasers

    Preservatives that slowly release formaldehyde.

  • Free from chemical uv filters of concern

    Restricted or debated filters with endocrine or reef-persistence questions.

Is Paula's Choice 10% Azelaic Acid Booster non-comedogenic?

This formulation contains 1 ingredient commonly associated with clogged pores — cetearyl alcohol.

If you are acne-prone, patch test or choose one of the alternatives below.
