Does Kérastase Genesis Serum Anti-Chute Fortifiant 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.

  • Free from silicones

    Slip and occlusion; cyclic silicones (D4/D5/D6) are the environmentally restricted ones.

  • Contains fragrance / parfum

    Found: parfum / fragrance. Undisclosed fragrance blends are the most common trigger for sensitised skin.

  • Contains essential oils

    Found: limonene, linalool. Naturally derived, but among the most frequently reported contact allergens.

  • Contains drying alcohol

    Found: alcohol denat.. 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 Kérastase Genesis Serum Anti-Chute Fortifiant non-comedogenic?

No ingredients in this formulation appear on Selenssa's common pore-clogger list, so it is unlikely to be the cause of congestion for most people. Comedogenicity is still individual — texture, occlusion and how much you use all play a part.

Is Kérastase Genesis Serum Anti-Chute Fortifiant safe for sensitive skin?

Usually tolerated, but patch test if your skin reacts easily.

  • Contains fragrance or parfum
  • Contains essential oils or common fragrance allergens
  • Contains a drying alcohol
