CHL

8/10

Concern level

High concern

Extract of the green microalga Chlamydomonas reinhardtii used in cosmetics primarily as a skin-conditioning, humectant-type ingredient. It is generally positioned as a moisturizing and barrier-supportive botanical active rather than a strong treatment ingredient. Because it is an extract rather than a single purified molecule, its composition can vary by manufacturing process and solvent system.

Risks & Warnings

Because extract composition can vary, impurity profile and preservative system matter. No specific pregnancy-related contraindication is established from the available cosmetic references.
