Ingredients higher up in an ingredient list are typically present in a larger amount. Bisabolol is a gentle skin conditioner, antioxidant, and soothing ingredient. It's primary claim to fame is soothing and research shows topically applied bisabolol can quiet the chemical messengers that cause your skin to become inflamed, helping to sooth any irritation. A clinical study found that applying 0.5% bisabolol daily for 8 weeks produced an average 9% decrease in skin pigmentation. Researchers found it can also suppress the process that leads to excess melanin production in skin. In vitro studies found that bisabolol combined with propylene glycol significantly increased skin permeability by increasing lipid fluidity in the stratum corneum. You'll likely see use concentrations quite low, usually 0.1-0.2%. Overall, this is a well-tolerated ingredient that works well in formulas designed for sensitive, reactive, or post-procedure skin. Chlorella Vulgaris Extract comes from a single-celled green freshwater algae. The version used in skincare is almost always a water or glycerin-based extract that is basically the algae's amino acids, peptides, sugars, and chlorophyll pigments. It acts as a skin-conditioning agent and the research behind it at this time is mostly lab-dish rather than human trials. Isolated Chlorella peptides inhibit collagenase and elastase (the enzymes that chew up collagen and elastin) and mop up free radicals in test-tube assays. Another study found a Chlorella gel sped up wound healing in mice. Many of the firming or dark-circle claims come from the ingredient supplier's own studies. Suppliers suggest using 1-2% of the trade version (Water/Glycerin + Chlorella Vulgaris Extract) in a finished formula which means the actual algae solids are a fraction of a percent. Allergy risk is low and topical reactions are rare; the 2020 anaphylaxis case came from eating Chlorella supplements and not from putting it on skin. However, patch testing is sensible if you have reacted to algae before. The "chlorella is high in iodine so it breaks you out" line borrows from marine seaweed. Freshwater Chlorella isn't a notable iodine source unless it's deliberately grown in iodine-enriched medium. Just so you know, many lists give algae a comedogenic rating of 5 and that number doesn't come from anywhere; it's not in the original rabbit-ear studies that most comedogenic ratings trace back to. The reasoning behind the reputation is that seaweed is high in iodine and iodine can trigger acne-like breakouts when eaten. This traces back to a 1976 letter in Archives of Dermatology describing two women whose breakouts cleared after they stopped taking high-dose kelp supplements orally. And the reaction of these two women wasn't clogged pores at all: it was an iodine-triggered pustular rash. Later research found normal dietary iodine doesn't meaningfully affect acne either and nobody has shown topical algae delivers eno
